Descrição da vaga

Senior Backend Engineer (Rust / Python / Cloud-Native Platform)

Location: Tagus Park, Portugal

Work Model: Hybrid – 3 days on-site

Contract: Full-time

Salary: €50,000–€65,000 gross/year × 14 salaries

Relocation: No relocation support provided (Only EU citizens, locals, or candidates with valid Portuguese residency will be considered)

About the Role

We are looking for a hands-on Senior Backend Engineer to build and evolve the backend services powering a next-generation Autonomous Mobile Robot (AMR) platform. This is a ~80% hands-on engineering role focused on distributed systems, event-driven architectures, and cloud-native platform development. This role requires a strong developer who wants to actively write production-grade code every day, rather than moving into pure architecture or management.

What You'll Do

• Build Backend Services: Develop and maintain scalable, high-performance backend services using Rust and Python.
• Evolve Distributed Systems: Work on cloud-native and edge-based systems running across cloud, edge, and robot environments.
• Develop APIs: Design, version, and implement robust REST APIs and service interfaces for fleet management, orchestration, and real-time monitoring.
• Ensure Code Quality: Build automated and integration tests directly into the development cycle while maintaining strict CI/CD pipelines.
• Collaborate & Mentor: Work alongside Frontend, Robotics, DevOps, and QA teams, while supporting junior engineers through code reviews.

What You'll Need

• Strong Backend Expertise: Proven experience developing high-velocity, production-grade distributed systems (not limited to simple CRUD applications).
• Language Proficiency: Strong professional experience in both Rust and Python, including asynchronous programming.
• Cloud-Native Stack: Hands-on experience with Docker, Kubernetes, container orchestration, and platform resilience tracking.
• Data Management: Solid background in PostgreSQL, Redis, data modeling, and query optimization.
• Engineering Discipline: Deep understanding of integration testing, secure coding practices, and observability/monitoring tools.

Nice-to-Have (Differentiators)

• Exposure to the robotics industry, AMR platforms, Fleet Management Systems, or ROS1/ROS2.
• Experience with communication protocols and messaging platforms like MQTT, gRPC, WebSockets, Kafka, NATS, or DDS.
• Background working on multi-tenant SaaS platforms or high-throughput data pipelines.
