Senior AI Engineer

Senior AI Engineer

About the Role

At Mindera, we believe in building software that improves lives. As a Senior AI Engineer you own the machinery that makes our accelerators reliable and reusable: the agent harness, orchestration, the platform-agnostic core, the evaluation infrastructure, and the observability that tells us whether a change made things better or worse. You are the reason delivery teams can trust output from a non-deterministic system.

What You'll Own

• The reusable accelerator core and the multi-agent workflows built on it
• Agent design across coding, planning, review, and testing agents, with tool-calling and human-in-the-loop where it earns its place
• The evaluation pipelines and telemetry that make quality measurable and regressions visible
• Reliability, cost control, and observability for agentic systems in real use

Key Qualifications

• At least 6 years of professional experience as an AI Engineer or in a similar role
• Strong production software engineering: Python, testing, packaging, CI/CD, async, REST, Docker. You build products, not scripts
• Real depth in LLM application engineering: prompt design, function calling, structured outputs, RAG, vector stores, with the Anthropic and OpenAI APIs
• Evaluation-driven development as a core habit, not an afterthought. You treat evals as the source of truth
• Experience building agentic systems end to end: systems that plan, write code, validate their own output, and improve over time
• Familiar with the orchestration landscape (LangGraph, LlamaIndex, AutoGen, CrewAI) and opinionated about when a thin custom harness beats a framework
• Working fluency with at least one cloud data platform and SQL: enough to build eval and verification infrastructure that your applied-data counterpart fills with domain rules. You do not need to be the deepest data expert in the room
