How does a Sr React developer typically collaborate with designers and backend engineers on projects?

As a Sr React Developer, you’ll regularly work with UI/UX designers to translate wireframes and visual concepts into functional, interactive web applications. Collaboration with backend engineers is also essential, as you’ll integrate APIs and ensure that frontend components communicate efficiently with server-side logic.

Job description

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 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#, 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.
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, driving technical excellence, and influencing the future of our product and roadmap.
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, including experience working directly with customers
  • A passion for learning and continual improvement, being comfortable giving and receiving constructive feedback to make your work even better
    • You can read more about our engineering values here
Great to haves
  • Familiarity with C#/.NET, JavaScript/TypeScript and React
  • Expertise with an OOP language (eg. Java, C++) and a modern JS framework (eg. Angular, Vue.js)
  • Proficiency in working on a distributed, cloud hosted product with rapid release cycles
  • 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 (the stuff you’d expect!)
  • Salary is £59k - £78k (depending on experience)
  • This role is based in our Cambridge office but with the flexibility to work from home when you need to
  • Opportunity to join our Long Term Incentive scheme
  • 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
  • Free lunch in the office
  • BUPA health care
  • Life Insurance & critical illness cover
  • Discounted gym membership, as well as a range of health and wellness benefits
