Much of your work will involve building flow components and agentic flows in the Flow Registry, the Python framework built on LangGraph within our Duo Workflow Service that powers agentic chat, and integrating them with the GitLab Rails monolith.</p><p>You’ll own complex backend features from start to finish across both services. You’ll integrate large language models and orchestrate multi-agent flows so customers can work faster and more securely across the software development lifecycle. This work sits where GitLab’s core platform meets its AI strategy, and reliability, performance, and answer quality directly shape the customer experience.</p><h2><strong>What you’ll do</strong></h2><ul> <li>Design and build flow components and agentic flows in the Flow Registry using Python and LangGraph within the Duo Workflow Service. These reusable building blocks power agentic Duo Chat and, increasingly, other AI features across GitLab.</li> <li>Develop, ship, and maintain backend features for GitLab Duo Chat across the Python Duo Workflow Service and the GitLab Rails monolith in a secure, well-tested, and performant way.</li> <li>Integrate new generative AI models, providers, tools, and multi-agent orchestration patterns into Duo Chat to expand its capabilities and improve answer quality.</li> <li>Design, implement, and review GraphQL and Representational State Transfer (REST) application programming interfaces (APIs) and related monolith logic, including chat entry points, permissions, and foundational-flow registration. Keep contracts with frontend clients and host systems reliable and clear.</li> <li>Improve debugging, observability, and test coverage using pytest, RSpec, and related frameworks; track and improve latency, error rates, and test coverage so AI-powered chat workflows stay reliable at scale.</li> <li>Collaborate with Product, User Experience (UX), frontend, and AI specialists to refine requirements and deliver high-quality improvements through iteration.</li> <li>Document standards, patterns, and learnings with other engineers, raising the bar for safe AI integration and evidence-driven engineering.</li> <li>Participate in Tier 2 on-call rotations to troubleshoot production issues, contribute to root cause analysis, and strengthen resiliency.</li> </ul><h2><strong>What you’ll bring</strong></h2><ul> <li>Significant experience building and maintaining production Python backends, including APIs, data models, and asynchronous or long-running workloads.</li> <li>Practical experience designing and shipping AI-powered, agentic backend features, including large language model integration, tool or function calling, and multi-agent orchestration. You use sound judgment about large language model limitations and safe use in production.</li> <li>Working proficiency in Ruby on Rails, or a strong willingness to learn it. Duo Chat integrates deeply with the GitLab monolith for chat entry points, GraphQL, permissions, and flow registration, and most of GitLab’s codebase is written in Ruby.</li> <li>Proficiency designing or extending REST or GraphQL APIs with attention to scalability, maintainability, and backward compatibility.</li> <li>Strong Structured Query Language (SQL) skills and familiarity with relational databases such as PostgreSQL, including efficient queries and data modeling.</li> <li>Ability to find, diagnose, and prevent performance and reliability problems at scale.</li> <li>Experience solving technical problems of high scope and complexity and advocating for quality, security, and performance improvements across your team.</li> <li>Openness to learning and collaborating in an async-first, distributed team, applying transferable skills from related technologies or domains. Hands-on experience with agent frameworks such as LangGraph or LangChain is a strong plus.</li> </ul><h2><strong>About the team</strong></h2><p>We’re part of GitLab’s AI Engineering organization and own the AI-powered chat experience embedded across the GitLab platform. Chat Engine is the backend-focused team within the Duo Chat group.</p><p>We’re backend, frontend, and AI specialists working asynchronously across time zones, using issues, merge requests, and documentation as our main collaboration tools. Our focus is to expand generative and agentic AI capabilities, improve the performance and reliability of chat workflows, and strengthen the debugging and testing foundations that let us run AI features safely at scale.</p><p>For more on how we work, see the <a href="https://handbook.gitlab.com/handbook/engineering/ai/duo-chat/" rel="nofollow ugc noopener" target="_blank">team handbook</a> page.</p><div>&nbsp;</div><div>Remote-Global</div><div><h3><strong>How GitLab Supports Full-Time Employees</strong></h3> <ul> <li><a href="https://about.gitlab.com/handbook/total-rewards/benefits/general-and-entity-benefits/" rel="nofollow ugc noopener" target="_blank">Benefits to support your health, finances, and well-being</a></li> <li><a href="https://handbook.gitlab.com/handbook/people-group/time-off-and-absence/time-off-types/#flexible-paid-time-off-pto" rel="nofollow ugc noopener" target="_blank">Flexible Paid Time Off&nbsp;</a></li> <li><a href="https://handbook.gitlab.com/handbook/company/culture/inclusion/tmrg-tmag/" rel="nofollow ugc noopener" target="_blank">Team Member Resource Groups</a></li> <li><a href="https://handbook.gitlab.com/handbook/total-rewards/stock-options/" rel="nofollow ugc noopener" target="_blank">Equity Compensation &amp; Employee Stock Purchase Plan</a></li> <li><a href="https://handbook.gitlab.com/handbook/people-group/learning-and-development/growth-and-development/" rel="nofollow ugc noopener" target="_blank">Growth and Development Fund</a></li> <li><a href="https://about.gitlab.com/handbook/total-rewards/benefits/general-and-entity-benefits/#parental-leave" rel="nofollow ugc noopener" target="_blank">Parental Leave</a>&nbsp;</li> </ul> <p>Please note that we welcome interest from candidates with varying levels of experience; many successful candidates do not meet every single requirement.

We build Pyroscope, the open-source continuous profiling database behind Grafana Cloud Profiles. Pyroscope gives engineers code-level visibility into how their applications use CPU and memory, down to the specific line of code, and connects that signal with metrics, logs, and traces across the Grafana stack.
Over the next year, you will help us:

Ship Adaptive Profiles as the default ingestion strategy, so customers automatically collect the profiles they need at a cost that makes sense.
Turn Pyroscope into a platform capability inside Grafana: bi-directional trace-to-profile correlation, integration with Kubernetes Monitoring and App Observability, and profiles surfaced where engineers already start their investigations.
Prepare Pyroscope for an agent-driven world: APIs, CLI, and docs designed so AI agents can drive profiling end to end, covering the full performance optimization lifecycle from finding an issue to verifying the fix.
Push operational excellence and TCO further: generalized autoscaling, better UX for long queries, and BYOC automation that brings up a new cell with zero manual intervention.
Double adoption by making profiling easy to start with: guided onboarding, use-case-driven docs, and assisted instrumentation so users get value in minutes instead of days.

What You'll Be Doing
As a Senior Engineer on Pyroscope, you will own meaningful projects end to end and help shape what the team builds next.

Lead projects from concept to rollout, e.g. Read path efficiency improvement, or trace-to-profile correlation, including design, delivery, operations, and customer follow-up.
Design, build, and operate core components of a distributed database: ingestion, storage, and query, making sharp trade-offs on performance, cost, and complexity.
Wear the product hat. We have no dedicated PM: engineers on this team join customer calls, translate pain points into manageable deliverables, and directly shape the roadmap. Your questions and ideas will steer what we build.
Drive operational excellence. Own outcomes against concrete SLOs and unit cost targets, reduce toil through automation, and make on-call quieter every quarter.
Partner across Grafana. Work closely with App Observability, Alloy, Tempo, and the other Databases squads to make profiles useful wherever engineers work.
Support your teammates through design conversations, code review, and pairing in a fully remote setup.
Participate in on-call (EMEA rotation) for the services you build, and treat incident response and post-incident learning as part of the craft.
Contribute to open source. Pyroscope is OSS. You will engage the community, review external contributions, and help steer the project in the open.

We invest heavily in developer productivity. You can use modern AI coding assistants as part of your daily workflow (your choice of tools, within security guidelines), backed by a company-funded usage budget so you can iterate quickly without unnecessary friction.
We encourage pragmatic AI-assisted development: faster prototyping, test generation, refactors, documentation, and incident follow-ups, always paired with strong code review and quality standards. You'll also have access to frontier models (e.g., GPT-5.6, Claude Fable, Gemini Pro 3.1).

Example problems you could work on
These are the kinds of projects landing this year:

Adaptive Profiles: sampling and aggregation strategies that keep the signal while cutting cost and noise, plus the ingestion metrics that make its behavior transparent to customers.
Large queries: query fairness, async execution, and autoscaling of the read path so long queries from our largest tenants run efficiently at any scale.
Traces and profiles together: bi-directional correlation between traces and profiles, so a slow request links straight to the code that burned the CPU.
Agent-ready Pyroscope: structured, deterministic APIs and a CLI that AI assistants can drive reliably, plus the benchmarks to prove tool quality and catch regressions.
BYOC and regions: cell lifecycle automation, from provisioning to migration, targeting a new cell end to end with zero manual steps.
OTel-native profiling: evolve ingestion, storage, and query as OpenTelemetry profiling matures, keeping Pyroscope the natural backend for OTel profiles.

What Makes You a Great Fit

Solid experience with a systems language. We write Pyroscope in Go; experience with one or more programming languages (e.g. Rust, C, C++, Python, Java, etc).
Distributed systems in production. You have built and operated cloud services and understand what it takes to keep a multi-tenant data system fast, reliable, and affordable.
Product sense. You are comfortable talking to customers, sitting with ambiguity, and breaking fuzzy problems into manageable deliverables. Since we have no dedicated PM, this matters as much as your code.
Curiosity and courage. Pyroscope is nearing feature completeness while still refining product-market fit. We need someone who asks hard questions and challenges the status quo when appropriate.
Strong software craftsmanship. You write clean, robust, performant software that others can maintain, and you know when to optimize versus when to ship.
Operational mindset. You have carried a pager, done SRE-style work or infrastructure as code, and treat reliability as a feature.
Pragmatism. You break complex problems into short feedback loops: analyze, design, deliver an MVP, learn, iterate.
Clear communication. You work well in a fully remote, asynchronous environment and lead through writing, reviews, and shipped code.

Bonus Points For

Experience with profiling and performance engineering: flamegraphs, pprof, perf, or similar tooling.
Experience with OpenTelemetry or large-scale observability systems.
Experience operating multi-tenant SaaS infrastructure at scale on Kubernetes.
Experience building for AI/LLM consumers: structured APIs, metadata and discovery endpoints, deterministic outputs.
Open-source contribution or maintainership, and comfort engaging a community in the open.
Experience as an on-call user of Grafana, Prometheus, Pyroscope, or similar in a previous role (or on a homelab).
Experience in a fully remote, globally distributed team.
