.NET Developer – £60,000 + Benefits – London

Do you want real ownership of the software you build, rather than being a small part of a large delivery machine? Are you ready to work directly with clients and see your code shape how a global industry operates?

Trigonal is a specialist software development company serving the global shipbroking and maritime derivatives sector, and we are looking for a .NET Developer to join our team in 2026.

The role

This is not a siloed developer position.

As part of a close-knit team of nine in the City of London, you will have direct influence over product direction, architecture decisions and feature design. You will work across front end, back end and APIs, gaining broad technical exposure rather than being limited to one layer of the stack.

You will be involved throughout the full software lifecycle, from refining requirements with clients to deployment and continuous improvement. Your work will be visible, valued and used by more than 40 international organisations.

Key Responsibilities

• Gather and refine requirements, often directly with clients
• Design and develop new platform modules and services
• Build and maintain API integrations
• Enhance and support existing systems
• Assist with deployments and ongoing system improvements
• Work across ASP.NET Core, React, C#, TypeScript/JavaScript and SQL

About our company

Founded in 2003, Trigonal has become one of the leading technology providers in a highly specialised global market. We develop software that underpins trading and risk management within maritime derivatives.

Our size is our strength. Decisions are quick, communication is direct and every team member plays a meaningful role in shaping our products. You will gain exposure to a unique sector while building technically robust, business-critical systems.

The Benefits

We recognise that career development, flexibility and stability matter.

• Competitive, negotiable salary based on experience
• 25 days’ annual leave plus UK public holidays
• Hybrid working, with a minimum of one day per week in our London office
• Potential to meet clients (home and abroad)

After six months’ continuous employment:

• Discretionary bonus scheme
• Contributory company pension
• Private medical insurance

You will benefit from genuine responsibility, direct access to decision-makers and the opportunity to broaden your technical and commercial understanding in a niche global market.

The person

You will have:

• 2–3 years’ experience in a commercial development role
• Strong grounding in .NET and modern web technologies
• Confidence working across front end, back end and APIs
• Clear communication skills and comfort speaking with clients
• Curiosity, initiative and a desire to build high-quality software

What’s next

If you are looking for a role where your work will have visible impact and long-term growth potential, please apply.
