💼 About the job:

We are looking for a Senior Backend Engineer to join a highly technical robotics software team building backend systems for autonomous inspection robots. This role focuses on designing and developing scalable APIs and backend services that power robot applications, enable integrations with customers’ facility management systems, and support new inspection workflows. You will contribute directly to improving robot performance and capabilities while shaping long-term backend architecture.

👷 About the Role

This is a hands-on senior backend role for someone who enjoys ownership, autonomy, and working in environments with evolving processes and uncertainty. You will design, implement, and maintain production backend systems that are reliable, scalable, and robust. You’ll work closely with robotics engineers and software teams, alternating between core backend development and operational problem-solving, with direct responsibility for the health and usability of the systems you build.

As a Backend Engineer, you will:

✔ Design, extend, and maintain scalable and consistent APIs for internal and external users.

✔ Implement backend features to enhance the main GUI and enable end-to-end inspection workflows.

✔ Debug, test, and monitor backend systems in simulation, in-house, and in the field.

✔ Integrate and evaluate solutions from external partners.

✔ Collaborate with other engineers, product managers, and designers to ensure seamless user experience.

✔ Write clean, maintainable, testable code and technical documentation.

✔ Communicate technical concepts clearly to both technical and non-technical stakeholders.

💡 Required Skills & Background

✔ Solid experience building maintainable backend systems and APIs in production environments.

✔ Strong problem-solving skills and ability to operate in environments with ambiguity and evolving priorities.

✔ Experience with AWS (Azure a plus) and web/cloud technologies.

✔ Strong coding skills in TypeScript; familiarity with Python or C++ a plus.

✔ Ownership mindset with ability to make decisions and build frameworks independently.

✔ Excellent communication skills, including explaining technical work to non-technical stakeholders.

✔ Willingness to travel occasionally (2–3 weeks per year) to co-locate with team members or customers.

🌟 What We Offer

✔ Base salary: €60,000–€85,000 for Backend roles.

✔ Phantom shares with a 4-year vesting period and 1-year cliff.

✔ Bonus: 7–15% based on annual goals.

✔ Health insurance costs currently covered via cash supplement; formal plan planned once Spanish entity is established.

✔ Perks: Lunch checks, team events (“Fabulous Fridays”), and two extra “recharge days” per year.

✔ Hybrid work model (2–3 days in-office) to ensure hands-on work with robots.

✔ Opportunity to work on cutting-edge robotics applications with a highly skilled international team.

💬 Ready to take on the challenge?

If you enjoy building backend systems that support robotics applications, want to work in a fast-moving, engineering-driven environment, and take ownership of your work, this role could be a great next step.
