Python Software Engineer (m/f)

We're seeking a passionate Python Software Engineer to join our agile team in Zagreb. In this role, you'll tackle robotics-oriented, production-level software engineering challenges by designing, developing, and enhancing multiple Python-based REST/ROS microservices that manage a fleet of AMRs (autonomous mobile robots) and coordinate warehouse operations such as loading/unloading trucks, destacking pallets, and picking up orders. You will also maintain in-house libraries, contribute to robot simulation tooling, support OTA deployments to customer sites, debug live systems against real hardware and logs, write production-grade code and tests, and more. Our Tech Stack: - Languages & Frameworks: Python 3.10+, FastAPI, Pydantic, asyncio, OOP, microservices, REST APIs, WebSockets, SSE, ROS, Bash - Databases & Messaging: MongoDB (Motor, Beanie), PostgreSQL (SQLAlchemy, Alembic), RabbitMQ (aio-pika), structlog - Robotics & Simulation: ROS topics/services, robot/mission/fleet state, telemetry & diagnostics, NumPy, OpenCV, in-house simulators - Tools & Platforms: Docker & Docker Compose, Ubuntu Linux, PyCharm, VSCode, Git, GitLab CI/CD, GitKraken, GitHub Copilot, pytest, pytest-asyncio, testcontainers, ruff, mypy, pre-commit, uv, Poetry, Nuitka, etc. Responsibilities we’ll trust you with: - Develop & Design: Build software for our robotics solutions using Python - fleet orchestration, mission lifecycle handlers, FastAPI services, ROS integrations, schedulers, and persistence layers backing real warehouse operations. - Collaborate: Work closely with diverse teams (robotics, product, QA, DevOps, and field engineers) to analyze user requirements and refine system architecture. - Ensure Quality: Conduct code reviews, implement tests, and follow best practices (CI/CD, design patterns, automation, observability) - including diagnostics for race conditions, recovery flows, callbacks, and deployment safety. - Innovate: Think of new solutions in the warehouse automation field, work and test with real robotic hardware and simulators, take full ownership of code quality and performance. - Travel: There are opportunities to visit our deployment sites in USA and Canada.

Your area of expertise: - Experience: 3+ years in Python development, REST APIs and databases - Education: BSc or MSc in Computer Science, Informatics, Mathematics, or a related field - Technical Skills: Proficiency in Python and Bash scripting; experience with REST, WebSockets, AMQP/MQTT, multithreaded/multiprocess/async programming; database design and ORM/ODM tools; testing (e.g., pytest); and log analysis/debugging across services, containers, and ROS nodes - Team Player: Excellent communication, collaboration skills, and a drive for innovation Bonus points: - Experience with GitLab CI/CD and ROS - Robotics, AMRs/AGVs, warehouses, WMS/WES, or similar industry experience - Familiarity with other programming languages such as C/C++, Go, or Rust and real-time data processing - Experience with event-driven systems, schedulers, state machines, or workflow engines - Familiarity with Docker Compose deployments, OTA updates, or edge-device operations - Experience with simulators, hardware-in-the-loop testing, or real robotic hardware
