The Opportunity

We Are Dcoded are partnering with a high-growth B2B SaaS fintech to appoint a Staff Software Engineer as they embark on building the next-generation version of their core platform.

This is a senior, hands‑on engineering role reporting directly into the Director of Software, where you will play a critical role in technical direction, system design, and engineering excellence across a modern, cloud‑native stack.

You will work at the intersection of architecture, delivery, and leadership, helping to shape how the product is built, scaled, and evolved while mentoring senior engineers and influencing engineering standards across the business.

What You'll Be Doing

• Acting as a technical leader within the engineering organisation, driving best practice across design, quality, performance, and security
• Playing a key role in the architecture and build of a new version of a complex B2B fintech platform
• Partnering closely with the Director of Software, Product, and Engineering Leads to translate business requirements into scalable technical solutions
• Leading on system design and technical decision‑making across backend services, APIs, and cloud infrastructure
• Remaining hands‑on in code, setting the standard for clean, maintainable, well‑tested software
• Supporting and mentoring senior engineers, contributing to a culture of continuous improvement and high engineering standards
• Helping to modernise legacy elements while ensuring platform stability, resilience, and scalability

Technology Environment

You do not need to be an expert in everything, but strong depth in several areas is expected.

• Backend : Go, Python, TypeScript, some .NET
• Frontend : React.js
• Cloud & Platform : Modern cloud‑native technologies (AWS / Azure / GCP), microservices, APIs
• Engineering Practices : CI / CD, automated testing, observability, performance optimisation
• Architecture : Distributed systems, scalable SaaS platforms, fintech or regulated environments (beneficial)

What We're Looking For

• Proven experience operating at Staff / Principal / Lead Engineer level within a SaaS environment
• Strong background in designing and building large‑scale, production‑grade systems
• Deep understanding of backend engineering, with experience across modern languages such as Go, Python, or TypeScript
• Comfortable working across multiple languages and paradigms, including some exposure to .NET

Experience building and scaling systems in the cloud

• Strong stakeholder management skills - able to influence technical direction without formal authority
• A pragmatic mindset, balancing technical excellence with commercial and delivery realities
