Senior Software Engineer

Company Description Software Alliance Limited (SAL) is a UK-based specialist software house, founded in 2006 to deliver financial modelling software and services for the insurance industry. Its flagship product, Mo.net, is used by clients worldwide for financial modelling, analysis, and strategic decision-making. SAL continues to grow as a market leader, offering opportunities to work on impactful, globally used software. We are looking for a Senior Software Developer to help shape the future of our products.

Role Description You'll work closely with our Head of Engineering to design and build the next generation of our platform while continuing to enhance and support our existing software, including our Windows desktop application and web-based financial modelling platform.

We're currently modernising our software solutions, so your ideas, experience, and technical expertise will have a real impact. You'll play an important role not only in development, but also in influencing architecture, technical direction, and engineering standards.

We're a small team, which means everyone has a voice. Communication is just as important as technical ability. Writing great code is only part of the role, you'll also need to collaborate effectively, explain technical decisions clearly, and work closely with colleagues across the business.

We work in an agile environment, but we're pragmatic rather than process-driven. We care about delivering value, solving real problems, and continuously improving how we work.
