Adria Solutions is recruiting a Senior Backend Engineer for a fintech business developing a new platform for digital financial services.

With established backing and its first engineering team taking shape, this is an opportunity to influence technical decisions, build services from the ground up and help shape how the team works.

The role

Reporting to the CTO, you’ll build reliable, secure backend services supporting banking and payments products. AI will form part of both your development workflow and the platform itself, with opportunities to deliver features such as intelligent assistants, process automation and document processing.

You’ll take ownership of features from design through to production, working closely with product, design and engineering colleagues.

Key responsibilities

• Build and maintain backend applications using Node.js.
• Develop APIs, database services and event-driven systems.
• Connect the platform with banking, payments and third-party services through REST and GraphQL integrations.
• Use AI coding tools to improve delivery while maintaining rigorous testing, security and code quality.
• Develop and deploy practical AI features that improve customer experiences and business processes.
• Own implementation, testing, deployment and ongoing support.
• Contribute to architecture, code reviews and engineering standards.
• Work collaboratively across product, design, platform and payments teams.

What we’re looking for

• At least five years’ commercial software development experience.
• Strong experience developing Node.js backend systems.
• Proven API design and implementation skills.
• Experience with relational databases, including PostgreSQL, MySQL or SQL Server.
• A background in integrating external services.
• Confidence using AI coding tools within an enterprise production development workflow.
• Strong knowledge of automated testing, Git, CI/CD and secure development practices.
• The ability to work independently and take ownership in a growing team.
• An interest in financial technology and improving access to financial services.

Desirable experience

• Banking, fintech, payments or another regulated sector.
• Delivering AI or LLM features into live products.
• Cloud platforms such as AWS, Azure or GCP.
• Containers and infrastructure as code.
• Mentoring colleagues or helping establish engineering practices.

The package

Alongside a £75,00–£85,000 salary, you’ll receive a generous holiday allowance with bank holidays in addition, pension contributions and a hybrid working arrangement based in Manchester.

The role also offers support for professional development, clear opportunities to progress and significant input into the technology and direction of a new engineering team.

Applicants must have the right to work in the UK without requiring visa sponsorship.
