Mid-Level Full-Stack Software Engineer (C#/.NET, React) in Belfast

Gearset is the leading DevOps platform for Salesforce. Our users can build and manage many aspects of their Salesforce development from within Gearset, from complex CI/CD pipelines to disaster recovery. The Gearset platform is a standalone tool that sits outside of the Salesforce platform, integrating via public APIs only. We work closely with domain experts to build novel solutions to the unique challenges they face, enabling them to make their Salesforce changes quickly and safely. We release new versions of Gearset multiple times a day and continually invest in improving our own observability and infrastructure tools.

As a product-driven company founded by engineers, we know the value of a great engineering culture, teamwork, and tight feedback loops. Engineering is mostly split between offices in Cambridge and Belfast.

What are the opportunities for a Mid-Level Software Engineer at Gearset? Our small engineering teams start from a few core principles but evolve over time. You’ll impact what we build, as well as how we build it. A great team does their best work with context and feedback—there’s no substitute for talking directly with the people impacted by our work. Engineers work across the business and talk directly to customers and partners to ensure we’re solving the most pressing problems. Our tech stack includes C#, Java, React, TypeScript, Postgres, AWS, and Kubernetes.

What you’ll achieve:

• Enhance and extend existing features, and collaborate with the rest of the development team to spec, design, and build new features end-to-end.
• Share your expertise and learn from a diverse team, fostering a culture of collaboration and continuous growth.
• Engage directly with users—understanding their challenges, gathering feedback, and shaping features that truly make a difference.
• Contribute opinions on a range of topics, from development practices to product strategy and roadmap, to impact business decisions.

About you:

• A pragmatic approach to working, prioritising iteration and delivering value to customers, over process and deliberation.
• Previous experience as a full-stack engineer.
• A passion for learning and continual improvement, being comfortable giving and receiving constructive feedback.

Great to haves:

• Familiarity with C#/.NET or Java, JavaScript/TypeScript, and React.
• Expertise with an OOP language (e.g., C++) and a modern JS framework (e.g., Angular, Vue.js).
• Proficiency in working on a distributed, cloud-hosted product with rapid release cycles.
• Experience working directly with customers.
• Experience working in an agile development team, where you’ve delivered incremental small slices, and are comfortable with reacting to meet user needs.

We believe that diverse teams perform better, so if your experience doesn’t fit perfectly or you don’t meet every single requirement but you’re excited about this role, we’d love for you to apply anyway.

Salary and benefits:

• Salary is £41k - £59k, depending on experience.
• This is a full-time opportunity, working Monday to Friday with the option of flexible home working (for most of us that looks like 2-3 days a week in the office).
• Generous personal development budget for courses, conferences, or whatever is useful to your professional development in the role of up to £1500 per year.
• Top-end hardware provided.
• Opportunity to join our Long Term Incentive scheme.
• Free lunch in the office.
• 25 days holiday plus bank holidays (with the option to buy an extra 5 each year).
• Company Pension Plan (matching up to 5%).
• Bupa health care.
• Life Insurance & critical illness cover.
• Discounted gym membership, as well as a range of health and wellness benefits.
