Senior Software Engineer

United Kingdom


Full time

We are looking for a Senior Software Engineer to join our rapidly expanding Product and Engineering team to help us build the leading SaaS product in supply chain and impact transparency.

You will define, build and maintain a dynamic and extensible platform that helps businesses gather, evidence and publish supply chain and impact information to create delightful and informative shopper-facing experiences. This includes engineering problems around platform usability, scalability and data flows, working with some of the world’s leading consumer goods brands and retailers.

Talking to our customers, leading on product demos and working with technical counterparts on integration and implementation requirements are important qualities of the role. 

Why Provenance?

Provenance is driving positive social and environmental change, by powering proof-backed sustainability communications. Our tech enables brands and retailers to communicate social and environmental impact with shoppers online - connecting claims to supply chain data and third-party proof. By doing so, Provenance enables shoppers to drive progress through what they buy and generates rewards for those brands making a positive impact on people and the planet. We’re a VC-backed scale-up with ambitious plans, and growing fast. Our customers are leading, global consumer goods brands and retailers in food, drink, beauty and fashion, where we believe we can drive the greatest change.

The role 

Working as a Senior Software Engineer at Provenance you will:

  • Define and build new features throughout the stack and integrations with blockchain tech and other services
  • Be involved throughout the product life cycle, from idea generation, design, and prototyping to execution, and shipping
  • Provide technical leadership and help influence product strategy: refining the system architecture, helping to define product features, and using best practice to enable the best quality end product.
  • Interface with customers working with the account team where required on product demos, technical integration and implementation
  • Collaborate closely with technical and non-technical counterparts to understand our customers' problems and build products that solve them 
  • Communicate complex technical concepts and solutions to team mates, customers and our wider engaged community of organisations and individuals
  • Lead on delivery, managing the development team through the sprint cycle, resolving blockers and coordinating meetings.
  • Take a lean, test-driven approach to solving problems
  • Proactively look for ways to improve our processes, software quality and maintainability
  • Continually build on your skillset to apply the best technology to solve a given problem

The technology

Our technology is based around a Ruby on Rails app combined with a mix of JavaScript and Preact on the frontend for blockchain integrity and user experience. Our stack currently includes:

  • Ruby on Rails, JavaScript/Typescript, Preact, StimulusJS, Webpack, Node, Solidity
  • Circle CI, Heroku, AWS, GitHub
  • We favour open-source technologies, write tests and run continuous integration, and review each other’s code through pull requests.

Ideally, you would be familiar with these technologies or similar patterns, however we are more interested in your ability to write clean, effective code and learn new languages quickly than of specific tools or libraries. Our software is constantly evolving, so we need engineers who are also looking to apply the best technology to solve a given problem.

You have an interest in future-facing technologies and believe in the potential for technology to help solve systemic challenges and enable positive change for people and planet.

  • Experience designing and architecting scalable, web-based systems that solve real business problems
  • Solid understanding of the various architectures and components of modern, scalable web application stacks
