Job description

Are you an experienced C++ developer with a passion for high-performance computing and geospatial technology? We are looking for a Senior Software Developer to join our expanding team in Bristol, and take ownership of core components that power advanced geospatial and sonar data processing workflows.

The Role

This is a key technical role where you will design, build, and optimise software that enables efficient data viewing, extraction, and generation of deliverables from large, complex datasets.

You will set the technical direction for the company's geospatial software and will be trusted to be the "source of truth" for all C++ development. With 45 days of annual leave and private health care (including dental) already guaranteed, you will have the time and peace of mind to focus on what really matters – building high impact software and changing the future of the offshore energy industry.

Working in a collaborative environment, you will influence architecture decisions and shape the future of the company's geospatial and sonar data processing tools. You will also get the chance to work across multiple platforms and languages, including Python interfaces, further broadening your skill set.

What You'll Do

• Design, implement, and maintain robust C++ software for geospatial and sonar data processing.
• Develop high-performance workflows for spatial analysis, mapping, and data fusion.
• Optimise code for speed, scalability, and memory efficiency across Windows and Linux platforms.
• Collaborate with data scientists and engineers to integrate C++ modules into wider systems, including Python interfaces where appropriate.
• Build and maintain automated tests, CI/CD pipelines, and performance profiling systems.
• Contribute to software architecture decisions, code reviews, and technical documentation.
• Stay current with modern C++ standards and industry best practices.

• Comfortable with cross-platform development for Windows and Linux.
• Python programming experience is advantageous.

Professional Qualities

• Extensive professional software development experience.
• Comfortable working across the full software development lifecycle - from requirements gathering to deployment.
• A proactive, solution-oriented approach with excellent problem-solving and prioritisation skills.
• Experience with geospatial, sonar, or 3D data formats is highly desirable.
• Background in the offshore survey or marine technology sector is a plus.

Why Join Us?

• Work on challenging, high-impact software used across the geospatial and marine technology sectors.
• Collaborate with a highly skilled, multidisciplinary IT team.
• Opportunity to shape core components and influence architectural decisions.
• Small supportive environment that encourages continuous learning and modern development and innovation practices.
