The Company

OCHO is partnered with a boutique professional services firm based in Belfast with a reputation for helping businesses and individuals navigate financial challenges.

With leadership buy-in and a collaborative, flat team structure, you'll be part of a tight-knit environment where your decisions have real business impact.

The Role

This is a hands-on Senior Software Developer position ideal for someone who thrives in full-stack .NET environments and wants to shape real-world tools used by legal and finance professionals. You'll architect features, write production-grade code, mentor junior engineers, and work directly with senior stakeholders.

If you're motivated by clean code, solid architectural decisions, and real business impact-this is your kind of role.

  • Lead architecture for new features and systems

  • Refactor and optimise legacy systems for performance and maintainability

  • Mentor junior developers through pairing, code review, and technical guidance

  • Work closely with business stakeholders, including senior leadership

  • Ensure all solutions meet compliance and security standards (e.g., GDPR)

  • Shape best practices across testing, deployment, and documentation

What Iam Looking For

  • 3-5+ years in commercial software development

  • Strong background in .NET stack and front-end frameworks

  • Experienced in CI/CD, Docker, and AWS ECS

  • Confident working with RESTful APIs and complex data flows

  • Clear communicator who's comfortable mentoring others

  • Bonus: experience in regulated or professional services environments

The Environment

  • Hybrid working with strong in-office collaboration

  • Flat structure - direct input into architectural decisions

  • Fast-moving product development with business value front and centre

  • Supportive team with mentoring responsibilities baked into the role
