Job description

Senior .Net Developer | Full Stack Engineer - Build the Future of Data Lineage & AI

London (Hybrid) | High-Impact SaaS Engineering Role

• C#, ASP.Net Core, TypeScript, React, Computer Science
• Company Size: Approx. 60

Spectrum Recruitment is partnered with a fast-growing, venture-backed SaaS company helping organisations understand and control complex data flows. Their platform enables enterprises to model, visualise, and manage data lineage, bringing clarity to some of the most challenging problems in modern data environments.

Why are they hiring?

Product Demand | Scale | Increasing team capabilities

As demand for the product increases and market interest builds the team needs greater experience and capabilities for scale. The current team is primarily made up of very clever graduates from ICL led by an experienced Head of Tech. They are looking for Developers to help the team evolve, add rigor and depth of knowledge to take the team and company to the next level.

Why This Role Stands Out

• Work on genuinely complex engineering problems involving data modelling, visualisation, and emerging AI capabilities.
• Own meaningful product features in a small, highly skilled engineering team.
• Use a modern technology stack with freedom to innovate and influence technical direction.
• Join a collaborative culture with R&D time, knowledge sharing, and hackathons.

Technology

C#, .NET Core, ASP.NET Core, TypeScript, React, cloud-hosted SaaS architecture, and exposure to AI-assisted development and data visualisation.

Who This Would Suit

Established, Senior Engineers who enjoy solving complex problems, care about clean architecture and UX, and want a role where their work has visible impact on both product and customers.

A degree in Computer Science or Software Engineering is a must.

Hybrid working (usually two days per week in a central London office) alongside a collaborative and ambitious engineering team. A friendly, sociable culture where people genuinely enjoy working together to solve complex challenges and have fun while doing it. You'll also have clear opportunities to learn, develop, and influence the future direction of the technology and team.

Interested?

If you're an experienced developer looking for a technically interesting role where your work genuinely matters, this is worth a conversation.
