FULLSTACK .NET/REACTJS
Position Overview
About the Role
We're hiring a Senior Software Engineer to join our Core Engineering team, building and maintaining the platform our customers rely on for KYC and investigation purposes. You will lead a small team of junior engineers, set the technical direction for the work they take on, and stay deep in the codebase yourself.
This is a hands-on leadership role. You will own initiatives from the first conversation with a stakeholder through to release and operation, and you will be accountable both for new delivery and for the health of the products already running in production.
What You'll Do
Own initiatives end-to-end: clarify and extend requirements with stakeholders across product, design, operations, and infrastructure, propose what to build, and see it through release and operation
Lead the junior engineers: set direction and goals, break down and estimate work items, unblock the team, pair on hard problems, and help onboard new joiners
Stay hands-on: write, test, and ship production code across our services in .NET Core / C#, TypeScript, and React, alongside the team
Own the existing products: maintain and extend the services already live, and lead defect resolution and incident response
Apply AI agentically: use approved AI tools like Claude Code across the full SDLC, and contribute back to our internal agentic ecosystem, the workflows and tools the rest of the team relies on
Code reviews: analyse and optimise code for quality and efficiency, and give constructive feedback
Design for scale: work with the Architecture team on efficient, scalable systems for complex applications, and drive the efforts that resolve performance bottlenecks and reduce technical debt
Own production readiness: testing, observability, security, CI/CD, and the Infrastructure-as Code templates for application-related AWS infrastructure
Run the team rituals: sprint planning, stand-ups, retrospectives, and the technical documentation that keeps the codebase understandable
Job Requirements
Bachelor's degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience
5 to 7 years of professional software development experience, including at least 1 to 2 years leading and delivering with a team of junior engineers
Strong hands-on experience with C# / .NET Core and TypeScript / React
Solid working experience with MS SQL Server and relational database design
Experience designing and running event-driven architectures, including queues and asynchronous processing, and the failure modes that come with them
Experience with Infrastructure-as-Code tooling (e.g. Terraform, AWS CDK, CloudFormation)
A track record of leading major initiatives successfully, from scoping through to release
Production mindset: a history of shipping high-quality work and achieving high reliability, backed by real habits around testing, observability, security, and CI/CD
Product instinct: comfortable shaping scope rather than waiting for a complete spec
Strong grounding in data structures and algorithms
Familiarity with Git and collaborative development workflows
Comfort working within an existing codebase and following and improving established patterns wherever applicable
Eagerness to learn, take feedback well, and grow within a structured engineering team
Clear written and verbal communication, and the patience to develop engineers earlier in their career
Nice to Have
Bonus points for an AWS Certified Solutions Architect - Associate certification
Familiarity with document and NoSQL databases (e.g. MongoDB, DocumentDB, DynamoDB)
