ClimateTech

Want to grow your backend skills while working on meaningful climate tech?

At Bohr, the software you build helps reduce methane emissions across Europe’s gas networks. This is an opportunity for a high-potential junior or early mid-level Java engineer to work on real-world systems that directly support cleaner, safer infrastructure and the transition to net zero.

About Bohr

Bohr exists to decarbonise energy through innovation.

Through our methane emissions division, Tectrac, we combine mobile leak detection technology with cloud platforms, analytics, and GIS-led insight. Our systems help utilities detect, prioritise, and repair methane leaks faster, cutting emissions and improving safety across the UK and Europe.

The Role

We’re looking for a Java Software Engineer to join our backend team and help develop the cloud-based platforms behind our methane detection and emissions intelligence systems.

You’ll work alongside experienced engineers, contributing to backend services that process survey, sensor, and geospatial data. This is a hands-on role where you’ll write production code, learn modern engineering practices, and gradually take on more responsibility as your skills grow.

You’ll also gain exposure to how systems run in production, occasionally supporting investigations into live issues and learning how reliability and performance are managed at scale.

What Success Looks Like

• Delivering well-tested Java features and API endpoints
• Learning and applying best practices around code quality and system design
• Contributing to reliable, regular releases
• Developing your understanding of cloud, data pipelines, and distributed systems
• Seeing your work support real reductions in methane emissions

What We’re Looking For

We’re looking for someone with a solid foundation in backend development, a strong desire to learn, and an interest in climate-focused technology.

Essential:

• 3+ years of commercial Java development experience
• Experience building or contributing to RESTful APIs
• Working knowledge of SQL databases
• Exposure to cloud environments (Azure preferred, others considered)
• Familiarity with version control, CI/CD, and automated testing
• Good communication skills and a collaborative mindset

Desirable:

• Interest in data-heavy, geospatial, or analytics-driven systems
• Some exposure to containers or microservices
• Curiosity about energy, infrastructure, or environmental data
• Motivation to grow into a more senior engineering role over time

Why Join Bohr?

At Bohr, you won’t be working on abstract features. The software you help build directly supports methane reduction, network safety, and net zero goals across Europe.

You’ll also get:

• Hybrid working with flexibility, based in our Bristol office
• Salary up to £50,000 (BOE)
• Pension contributions
• 25 days holiday plus 8 bank holidays
• Participation in our EMI share scheme

If you’re a Java engineer looking to step up in a supportive, impact-driven environment, this is a great opportunity to do exactly that.
