Job summary

Mindera is seeking a Senior AI Engineer for AI Systems to own the accelerator core, agent harness, and evaluation infrastructure. You will drive reliability, scalability, and observability for non-deterministic AI systems and empower delivery teams to trust outputs.

You will design agents across coding, planning, and testing with tool-calling, plus human-in-the-loop where appropriate, and shape the AI SDLC for production apps.

Qualifications

• 6+ years of professional experience in AI Engineering or Software Development.
• Experience deploying customer-facing apps including DevOps, frontend and backend.
• Proven track record building scalable, modern production apps.
• Hands-on experience with AI SDLC in production.
• Deep expertise in LLM applications: prompts, function calling, structured outputs, RAG, vector stores, APIs.
• Experience building end-to-end agentic systems that plan, code, validate, and improve.

Responsibilities

• Own the reusable accelerator core and multi-agent workflows.
• Design agents across coding, planning, review, and testing with tool-calling and human-in-the-loop when needed.
• Develop evaluation pipelines and telemetry for quality and regressions.
• Ensure reliability, cost control, and observability for agentic systems in production.

Job description

At Mindera, we believe in building software that improves lives. As a Senior AI Engineer for AI Systems 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 relevant for the role (probably a mix of AI Engineering and Software Deveopment).
• Can deploy a working customer facing app themselves including devops, front end, backend etc
• Has experience building a production app which was modern, could handle scale, fast, responsive etc
• AI SDLC in production experience
• 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.

The Things We Really Care About:

• Health Insurance, because health comes first.
• Flexible working hours.
• Open holidays, take the time you need for yourself.
• Profit distributionfor everyone.
• Mindera Annual Trip, Sports, and sharing groups to connect and have fun!
• Training & conferences, create your own training plan.

Other Good Things:

• Choose Laptop & Peripheralsthat best suit your needs.
• Hotspot with unlimited usage, for work or Netflix
• Remote culture:We have an office in Casablanca, but Minders work remotely from all over Morocco.
• At the offices, we have a wide range of snacks to keep you fed and healthy and partnerships with local businesses.
