Senior Backend Engineer (.NET) — Small Team, Big Impact

Work directly with founders. Build things that matter. Learn fast. Move faster.

At Bond, we’re not a large corporation with layers of management and slow-moving projects. We’re a tight-knit product and engineering team building something ambitious — a platform that transforms how member-based organisations connect, engage, and grow.

Our clients include unions, associations, educational, and healthcare sector bodies that require secure, intuitive tools to serve their members. We help them do it better through our suite of integrated products: CRM, finance, learning, engagement, and community modules — all built in-house by our team.

We’re growing quickly, and we need the right people on board — not just great engineers, but adaptable, curious minds who thrive in fast-paced environments where priorities shift, decisions are made quickly, and results matter.

We’re looking for a Senior Backend Engineer who’s excited to work at the heart of a small, dynamic team. This is a hands-on role where you’ll solve complex problems and contribute directly to the success of our platform and our clients.

You’ll work closely with our founders, product leaders, and developers across:

• Designing and building robust backend services and APIs in .NET
• Translating real-world business logic into clean, maintainable code
• Integrating with third-party services like Stripe, Twilio, AI/ML APIs
• Helping define and evolve our tech architecture and dev practices
• Maintaining and modernising some legacy systems (ASP.NET MVC and .NET Framework)

While this is a backend-heavy role, we welcome individuals with full-stack capabilities or interest, especially those who are eager to learn quickly and take on broader responsibilities.

Let’s be clear: this isn’t a cushy enterprise job with siloed teams and a 12-month roadmap.

• We move fast. Priorities shift as we respond to real user needs.
• You’ll be exposed to product discussions, client feedback, and tech decisions.
• We value outcomes over ego — everyone contributes, no one hides behind a title.
• You’ll learn more in 3 months here than in 3 years at a slow-moving shop.
• We don’t have HR, middle managers, or bureaucratic blockers — just good people doing good work, fast.

If you’re looking for a big brand name, this probably isn’t for you. If you want autonomy, accountability, and a seat at the table, let’s talk.

Core Backend (Required):

• 5+ years’ experience in backend development using .NET / C#
• ASP.NET Core, Web API, RESTful services
• .NET Framework and ASP.NET MVC for legacy support
• SQL Server (NoSQL a plus)
• Azure cloud services and Azure DevOps pipelines
• Strong understanding of software design patterns and architecture

Frontend (Nice to Have):

Bonus Points:

• Stripe, Twilio, Campaign Monitor or SendGrid integration
• Azure AI Search, Azure Bot Service
• Power BI or similar tools for reporting and data visualisation
• CI/CD pipelines, microservices, or event-driven design
  

• Someone who can work independently but thrives in team collaboration
• You’re not afraid to ask questions or challenge assumptions
• You care about clean code, fast delivery, and real outcomes
• You’re comfortable when things aren’t perfect yet — and can help make them better
• You like building smart systems that real people rely on
• You’re a proactive communicator — especially important in our remote-first culture
