Description
Senior .NET Developer | Up to £75,000 | Hybrid in Oxford
develop is partnering with a well-established, values-led ecommerce business to hire a Senior .NET Engineer who is looking to take the step into a Lead position. The role formalises technical leadership in a small, high-trust engineering team.
The business is mid-way through a major period of change: replatforming, a finance systems transformation, and legacy modernisation and cost optimisation on AWS. You’ll be a key voice in technical decisions, working closely with a CTO-level leader who is consulted on strategy by the senior leadership team.
The role
- Roughly 60% hands-on development and 40% technical leadership. This is not a people-management role
- Stay close to backend development and architecture
- Set and maintain coding standards and engineering best practices
- Lead code reviews across UK and Ukraine-based development teams
- Mentor junior and mid-level developers
- Contribute to architectural decisions and lead proof-of-concept projects
- Support the migration and modernisation of legacy systems into AWS
- Help improve delivery speed, consistency and team performance
The environment
.NET / C#, AWS (ECS, SQS), Docker, microservices, SQL Server and NoSQL, Bitbucket CI/CD, with third-party and ecommerce platform integrations. Upcoming projects include a new pricing engine, order management and fulfilment improvements, with scope to explore AI/ML in pricing.
What we’re looking for
- Strong commercial .NET / C# experience (around 6+ years, though track record matters more than years)
- Strong AWS experience
- Experience building and maintaining microservices
- Good understanding of Docker, containers and modern CI/CD
- Experience with both SQL and NoSQL databases
- A proven record of code reviews and mentoring, with leadership experience either formal or informal
- Collaborative and approachable, with strong opinions held lightly
- Happy to stay hands-on and take ownership
Nice to have:
ECS and SQS, legacy migration, ecommerce integrations, AI/ML exposure.
What’s on offer
- Salary up to £75,000
- Strong benefits package
- Flexible, relaxed working culture (Tues/Wed/Thurs in the office)
- A purpose-led business with a strong charitable focus
