Senior Software Engineer Bristol (GB) Professionals

Location: Bristol, UK

Approach: Hybrid Remote, typically 2-3 days per week in the office

Contract: Permanent, full-time

Rosenxt is revolutionising subsea robotics and autonomous systems, and we are building a world-class engineering team at our Bristol location to drive this innovation forward. To build our engineering team we are recruiting for top-tier talent that is keen to:

• Build robust software that runs on real robots to tackle real-world applications.
• Lead by example to champion modern and effective software development practices in a dynamic and growing engineering team.
• Tackle engineering challenges at all levels of a robotics software stack.

In this role, you will work on cutting-edge technology that makes a real-world impact - from developing our visual inspection platform to creating autonomous systems that operate in some of the world’s most challenging environments. You will have the opportunity to see your work in action through field trials and real-world deployments, all while working in a collaborative, hybrid environment in central Bristol.

Within a cross-functional team, you will contribute towards the entire software development lifecycle, including design, implementation, testing, and maintenance of our products. Working primarily in C++ and Python, you will employ high-quality software engineering principles and practices. You will be actively engaged in building quality solutions within an Agile process, including peer reviews, continuous improvement, and integration.

If you are passionate about robotics, love solving complex technical challenges, and want to mentor others while growing your own expertise, this role offers the perfect blend of technical depth, leadership opportunity, and meaningful impact.

What you can expect

• Architect and develop new capabilities for autonomous robotics, subsea perception, and underwater structure inspection.
• Write and maintain high-quality, efficient, and scalable code using modern C++ and Python.
• Practice and advocate for high-quality engineering standards such as design patterns, SOLID principles, TDD, and CI/CD. Lead by example.
• Ensure software reliability and performance through rigorous quality standards, including comprehensive code reviews, unit testing, and continuous integration.
• Work across all phases of the product lifecycle, from concept and design through to deployment and maintenance.
• Stay abreast of the latest industry trends, tools, and technologies to keep our solutions competitive.
• Take part in continuous improvement initiatives to enhance development processes, tools, and product quality.
• Mentor and support junior engineers, fostering a collaborative, innovative, and growth-oriented environment.
• Work closely with product teams to define requirements, objectives, and deliverables.
• Coordinate with cross-functional teams (ML, Simulation, Robotics) to ensure seamless system integration.
• Engage with stakeholders to gather feedback and ensure solutions meet their needs.
