Senior Product Engineer
NscaleUnited Kingdom
UK
We’re seeking a Senior Product Engineer to build high-impact product features end-to-end — and to leverage AI to scale your own impact. You’ll work across discovery, implementation, and iteration: turning ambiguous problems into shipped outcomes, using LLMs and classic ML pragmatically (where they help), and instrumenting everything for quality, cost, and engagement. This is a hands-on role for a builder who codes daily, partners tightly with Product/Design/Platform, and uses AI tools (generation, retrieval, agents, automation) to move faster with higher quality.
What You’ll Do
- Ship product features end-to-end across backend, APIs, and UI (Python/TypeScript/React or equivalent).
- Use AI as a force multiplier: speed up specs, scaffolding, tests, refactors, data exploration, incident triage, and docs with modern AI tools.
- Add AI-powered user value when it helps: search & RAG, summarization/tagging, recommendations, assistants/automation — always measured against baselines.
- Instrument everything: define KPIs (quality, latency, cost, engagement), set up offline/online evals, A/B tests, and telemetry.
- Build reliable services with CI/CD, canaries/rollbacks, observability (metrics/logs/traces), and clear SLOs.
- Own data flows for features: ETL for embeddings/indices, feedback loops from clicks/dwell/ratings, guardrails for safety and privacy.
- Collaborate with Product/Design on discovery, UX, and roadmap; writes clear specs that feed into how the system is built, tested and documented (context engineering) and drive good decisions quickly.
- Ensure security/IAM and governance (PII handling, RBAC, auditability) in everything you ship.
- 7–10+ years in product/software engineering with a record of shipping user-facing features at scale.
- Strong Python; comfortable across API + web app stacks (FastAPI/Flask/Node, React).
- Demonstrated pragmatic use of AI in products and workflow: prompt/adapter tuning, retrieval, evals, and cost/latency trade-offs.
- Solid engineering fundamentals: system design, testing, code quality, performance, and operational ownership in cloud environments.
- Experience with instrumentation, A/B testing, and analytics to guide iteration.
- Security mindset (privacy, RBAC/IAM, auditability).
- Knowledge graphs or personalization/recommendation experience.
- Agentic workflows (tool use, routing) with safety guardrails.
- ML/LLM observability, eval frameworks, or GPU inference optimization basics.
- Contributions to open-source or internal frameworks that improve developer velocity.
