We're looking for a Senior Backend Engineer to join a deep-tech project developing AI-driven simulation software for advanced engineering and manufacturing industries.

The goal of this project is to accelerate hardware innovation through intelligent, high-fidelity simulations — enabling engineers to design, optimize, and manufacture products faster and smarter across domains like aerospace, energy, and automotive.

This role is ideal for a self-driven and proactive engineer who thrives in an evolving environment where not everything is structured or predefined. You'll work with a small, talented team on complex technical challenges, take full ownership of your deliverables, and have the freedom to shape solutions from concept to deployment.

Responsibilities:

  • Design, develop, and maintain backend services using Python (FastAPI, REST API).
  • Build, containerize, and orchestrate services with Docker and Kubernetes.
  • Implement GitOps workflows and contribute to CI/CD pipelines.
  • Collaborate closely with frontend, AI/ML, and cloud engineers to integrate components smoothly.
  • Ensure solutions are secure, reliable, and scalable in AWS cloud environments.
  • Write clean, maintainable, and well-tested code — and proactively suggest improvements across the stack.
Requirements
  • Expertise in Python, including FastAPI and REST API development.
  • Hands-on experience with containerization (Docker) and orchestration (Kubernetes, Helm).
  • Familiarity with GitOps, CI/CD, and cloud deployments (AWS preferred).
  • Solid understanding of software architecture, testing, and performance optimization.
  • Strong communication skills and ability to work directly with technical and non-technical stakeholders.
  • A self-sufficient, proactive mindset — comfortable working in a fast-moving, less-structured startup environment where documentation is still evolving.
  • Fluent in English.

Nice to Have:

  • Experience with 3D geometry data or computational simulation.
  • Familiarity with infrastructure security and best practices in DevOps.
  • Knowledge of PostgreSQL (not required but useful).
  • Exposure to AI/ML or numerical simulation environments.

Who You Are:

  • Communicative and collaborative, able to explain ideas clearly.

  • Proactive and curious, taking ownership from problem to solution.

  • Flexible and adaptable — you see change as an opportunity, not a challenge.
  • Passionate about solving complex engineering problems with modern technologies.
Benefits
  • Choose your contract: B2B/C2C,
  • Unlimited working-from-anywhere policy,
  • Referral Bonuses,
  • Working on international projects
