Senior Software Engineer

🏡🏢The role starts out remote. Once we establish an office, it will move to a hybrid set-up of two days a week on site.

The Role

We're looking for Senior Software Engineers to help us build the products that small businesses across the US and UK rely on every day. You'll work across cross-functional teams alongside Product Managers, QA Engineers, and fellow Software Engineers, owning problems end to end, from the first line of code through to production, monitoring, and continuous improvement.

This isn't a role for someone who wants to be handed a ticket and told what to build. We're looking for engineers who understand the problem, challenge the approach when it needs it, and take pride in the quality of what they ship. We only build what the customer wants.

What You’ll Be Doing

• Designing and building robust, scalable solutions in .Net taking full ownership of the SDLC from concept through to production
• Playing an active role in architectural decisions and technical direction, shaping how things are built, not just building them
• Working closely with Product and QA, bringing your technical perspective early and often
• Writing bulletproof unit and integration tests and holding a high bar for code quality across the team
• Communicating clearly across technical and non-technical stakeholders, translating complex engineering decisions into business context
• Mentoring and supporting engineers around you, raising the standard of the team as well as your own output

 

We’re Looking For 🔎
Required skills:

• 5+ years of hands-on experience in C#, .Net and SQL Server with ideally some experience in front-end development
• A clear sense of what senior means. Not just years in the seat, but ownership, judgement, and the ability to operate with ambiguity
• Strong testing practices across unit and integration testing
• Broad engineering knowledge that goes beyond your core stack; the kind of depth and curiosity that comes from solving hard problems in complex, distributed systems
• The ability to communicate clearly and confidently, with your team, with Product, and with the wider business
• Experience working in agile, cross-functional teams
• Someone who's proactive, direct, and makes the people around them better

 

Our Tech Stack

• Backend: C#, .Net, .Net Core
• Frontend: React, Typescript
• Mobile: Flutter, Dart
• Databases: SQL Server, MongoDB
• Cloud: Azure & GCP

Interview Process 🤝

• First stage: 30-minute intro, CV review, and values with a Talent Partner
• Second stage: 45-minute “Tech Chat” with a Team Manager
• Final stage: 90-minute Code Pairing + 30-minute Values Interview

Diversity & Inclusion 🌈
We welcome, consider and encourage applications from anyone who shares our commitment to inclusivity. Join us in creating a space where authenticity thrives, and everyone can do their best work.
