Lead/Senior Software Engineer

Location: Northampton
Salary: £65,000 - £75,000
Job type: Permanent, Full-time
Visa Sponsorship: Not available

We're looking for a capable and hands-on Lead or Senior Software Engineer to take ownership of core systems, lead development efforts, and help shape how technology supports the business. This isn't a detached management role, it's for someone who still enjoys getting into the code, solving engineering problems, and helping others level up.

You'll be joining a small in-house team working on a wide range of software and infrastructure projects from building APIs and integrating systems, to modernising Legacy platforms and managing cloud deployments.

What you'll be doing

• Leading technical delivery on internal systems and Back End services

• Designing, building and maintaining APIs, message queues, and cloud-hosted infrastructure

• Working across a modern Microsoft-based stack with a mix of Legacy and greenfield

• Collaborating with product, data, and operational teams to scope and deliver tools that actually solve business problems

• Improving security, deployment processes, and performance across environments

• Mentoring junior devs and helping steer architectural decisions

• Taking real ownership of how software gets delivered and supported

The stack you'll be working with

• C# and .NET (Legacy and modern)

• Redis, RabbitMQ, SQL Server, Postgres

• Git for source control

• Azure and AWS

• HTML, CSS, JavaScript (some UI work, but not a full Front End role)

• Bootstrap and SOLR (bonus if you've used them)

What we're looking for

• Strong experience with C#/.NET in a commercial setting

• Confident building and integrating APIs and Back End services

• Familiar with message queues, caching tools, and cloud-hosted environments

• Practical understanding of infrastructure, deployments, and application security

• Someone who can work independently and lead by example, while collaborating with others

• Comfortable balancing Legacy maintenance with modernisation projects

• Bonus points for experience with SOLR, Bootstrap, or hosting migrations

What you'll get

• £65,000 to £75,000 salary, depending on experience

• Hybrid working, on-site when needed, remote when it makes sense

• 25 days holiday + bank holidays + your birthday off

• Christmas shutdown

• Pension scheme

• Discretionary bonus scheme

This is a role for someone who wants responsibility, freedom to make decisions, and the satisfaction of building systems that actually matter to a growing business. If that sounds like you, we'd love to hear from you.
