  • Remote 13 WFH days per quarter — job description

The job, in the employer's words

We're building production AI agents that change how our engineering org ships code and how employees work with internal knowledge. You'll join a small, high-ownership team. You'll write the agent logic, the tools, the data layer, and the pipelines that make them dependable at scale. Turn architecture into reliable, well-tested, production-grade systems.

Role and Responsibilities :

  • Implement agent logic, tools, and orchestration against the given architecture.
  • Build and tune RAG pipelines: ingestion → embeddings → retrieval → re-ranking → evaluation
  • Design and optimize Postgres schemas, queries, and vector indexes for production load
  • Build the test-generation and test-execution engine for the AI Code Pipeline
  • Integrate with Git, CI/CD, and internal services
  • Build evaluation harnesses, observability, and guardrails so agents are measurable and safe
  • Own the reliability, latency, and cost of the systems you ship
  • Write clean, typed, well-tested Python and participate actively in code review

Requirements

  • 4+ years of professional software engineering in Python, with deep, hands-on command of the language : async, typing, packaging, performance, and clean, maintainable code
  • 1+ years building LLM / agentic systems — tool use / function calling, orchestration, prompting, and evaluation
  • Strong problem-solving and debugging on ambiguous, real-world production problems.
  • Solid Postgres experience: schema design, query optimization, and extensions (pgvector)
  • Experience shipping and operating production services — testing, CI/CD, observability, on-call mindset
  • Comfort with Git-based workflows and code review
  • Automating software testing: unit, integration, functional, security, performance
  • Integrating with developer tooling and CI/CD systems
  • 6+ months of demonstrated experience building with Claude Code in a development workflow

Benefits

  • Hybrid Office - 13 WFH days per quarter
  • Company bonus
  • Ticket Restaurant
  • Private Health Insurance
  • Flat hierarchies and short decision-making paths
  • Cooperation in a highly motivated, young, international team spread across 3 continents
  • An attractive location in a creative and modern office
