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 * **Our values** We are a company that seeks the best for both our employees and clients, reaching beyond expectations in turning dreams into reality.
