Senior Full-Stack Software Engineer (C#/.NET, React)

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. So while our engineering team doesn’t develop within the Salesforce environment, our users do. So we work closely with those domain experts to build novel solutions to the unique challenges they face, enabling them to make their Salesforce changes quickly and safely.

We live and breathe this approach ourselves: we release new versions of Gearset multiple times a day and we continually invest in improving our own observability and infrastructure tools. This means we can identify and react to issues quickly and delight our users by getting improvements to them as fast as possible.

As a product-driven company founded by engineers, we know the value of a great engineering culture, teamwork and tight feedback loops. We’re confident in our product, market potential, and we have big plans for the future.

What are the opportunities for a Senior Software Engineer at Gearset?

• Our small engineering teams start from a few core principles but evolve over time. They all work a little bit differently, depending on their preferences and the problem they’re working on. You’ll have input into 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 getting value from our features. 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#, React, TypeScript, Postgres, AWS and Kubernetes. You’ll become familiar with our pragmatically chosen stack, but you’ll also help us define what great looks like.

• You’ll have access to leading LLMs and AI development tools to support your work, with a collaborative culture and dedicated internal channels for sharing AI tips and tricks to help everyone grow.

What you’ll achieve

• Enhance and expand our platform, collaborating with the rest of the development team to 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.

• Play a key role in shaping development best practices, advancing technical excellence, and contributing to the future of our product and roadmap.

About you

• A collaborative approach to working, prioritising iteration and delivering value to customers, over process and deliberation

• Previous experience as a full-stack engineer, including experience working directly with customers

• Expertise with an OOP language (eg. Java, C++) and a modern JS framework (eg. Angular, Vue.js)

• A passion for learning and continual improvement, being comfortable giving and receiving constructive feedback to make your work even better
