Senior AI/ML Engineer

About the Role: We're looking for a senior AI engineer who thinks in context strategies, agent architectures, and quality feedback loops-and can also write solid backend code. This is a production AI engineering role, not research or data science. You'll own significant parts of our AI engine, ship agentic workflows end-to-end, and drive measurable quality improvements on real customer problems. You'll be autonomous, hold systems end-to-end, and use AI tools as a natural part of your daily workflow. You'll raise the engineering bar across the team through clean code, systematic testing, and sharp code reviews. Responsibilities: • Own the AI engine: Design and evolve context architectures (templates, few-shot examples, structured outputs); manage context window limits; optimize for quality and cost; validate schemas and handle edge cases • Architect and ship agentic workflows: Design agent boundaries, clean tool interfaces, failure handling, and human oversight points; manage agent state across turns; ensure robustness through guardrails and graceful degradation • Drive AI quality: Define success criteria before shipping; build and run eval sets; catch regressions before users do; analyze failure patterns systematically; iterate on evidence, not gut feel • Own AI production operations: Trace LLM calls and agent steps across the stack; monitor cost and latency; set SLOs; respond to incidents; establish operational runbooks • Write solid Python backend code: Build APIs, microservices, and database schemas that support the above; own deployment and on-call for your services • Raise the engineering bar: Champion clean code, the testing pyramid, and sharp code reviews across the team Must-Have Requirements: • 3+ years shipping AI/LLM-powered features in production (not research, not prototypes) • Hands-on context architecture design: Prompt engineering, structured outputs, schema validation, few-shot design, context window optimization • Experience building and operating agentic systems: Tool interface design, orchestration patterns, failure handling, agent state management, multi-turn conversations • Systematic approach to AI quality: Eval sets, success criteria definition, failure pattern analy- sis, evidence-based iteration • Production AI observability: Tracing LLM calls and agent steps, cost monitoring, latency tracking, incident investigation • Proficiency in Python (production-grade, enterprise experience) • Solid backend fundamentals: APIs, microservices, SQL database design and optimization • Daily hands-on use of AI development tools (Cursor, Claude Code, Copilot, or similar) — this is a hard requirement • Fluent English (written and verbal) • Self-driven, product-minded, no hand-holding needed Has owned a non-trivial AI feature or agentic workflow in production for 12+ months — context design, evals, on-call, iteration on real user feedback What You'll Work On in Your First 3 Months: • Build and ship a new agentic workflow end-to-end — design, tools, evals, rollout to a real client • Tackle a class of LLM reliability issues (e.g. streaming timeouts with reasoning models, gateway fallback edge cases) • Close observability gaps so a single conversation can be traced cleanly across our stack Nice to Have: • Experience with LLM orchestration frameworks (LangChain, LlamaIndex, LangGraph, etc.) • Multi-agent system design and operation • Model routing, cost governance, or LLMOps tooling • Familiarity with evaluation frameworks (LangSmith, RAGAS, custom harnesses) • Observability tooling (Datadog, Grafana, OpenTelemetry, Langfuse) • AWS infrastructure experience (Terraform, Ansible) • Node.js or TypeScript backend experience Why Join Us: • Join a small team of passionate engineers dedicated to innovation and excellence • Work on a product that genuinely improves people's lives and workplace safety • Experience a startup culture: fast-paced, close collaboration, real influence on key decisions • Short feedback loops — ship fast, learn fast • Minimal bureaucracy — focus on what matters: building great software • AI-first engineering culture — we embrace and invest in AI-augmented development Interested in joining our team? Send your CV and a brief cover letter. Please include: • Your GitHub profile or portfolio (if available) • A brief note on your experience with AI/LLM tools • Your availability and preferred start date We review applications on a rolling basis and aim to respond within 5 business days.
