Our Mission

The world’s rate of decarbonisation needs to be 10x faster. The largest, most complex organisations contribute an outsized amount to the problem but lack the trustworthy, decision-grade data they need to reduce their environmental impact (and, while very important, decoding how to comply with ever-increasing reporting standards takes precious time away from sustainability leaders who need to be driving change in their organisations).

Minimum solves this challenge by structuring and unifying the world’s environmental data. We are the Environmental Data Layer which large, complex businesses use to transform their existing data into high-quality, high-trust environmental data at scale. Unlike others in the space, we’re ruthlessly focused on solving data acquisition, processing, and calculation challenges.

Where we’re up to

• We’re a late seed-stage business backed by top-tier investors, including NEA (unannounced), Lakestar (unannounced), Octopus Ventures, Y Combinator, and more.
• Our product is used by a range of large public and private companies, including Volkswagen, UK Power Networks, Games Workshop, Nasdaq (and many more) to streamline their data processes, meet stringent international reporting requirements, and gain valuable insights on how to decarbonise their business.
• Our team is passionate about evolving our product to the next level, ensuring we’re delivering the most value possible to customers as quickly as possible, and scaling up our sales & distribution engine as we serve more and more Enterprise customers.

The Opportunity

• This is an opportunity to contribute to shaping and building up a product and company that is genuinely changing the world and solving real problems for customers. Minimum’s platform is just one small part of solving the climate crisis, but we’re dedicated to driving enormous value through our slice of the overall solution.
• Carbon accounting has been estimated to be a $60B market opportunity. We believe that’s an underestimate. Organisations of all shapes and sizes across the globe are being forced to improve their carbon data to meet increasing reporting and decarbonisation requirements from governments, investors, and customers. Sustainability is no longer a ‘nice-to-have’ for forward-thinking companies; it’s an absolutely essential compliance and commercial imperative for all businesses.
• Our market-leading product is actively delivering value to large Enterprise customers, but in the context of the full scope of what we want to achieve, our work has only just begun. There are opportunities to drive incredible amounts of customer value by doubling down further on what we’ve already built, solving even more pain points, and pursuing closely adjacent opportunities, such as integrating AI into data workflows or enabling automatic acquisition of energy data from the point of consumption.

The Role

As a Senior Frontend Engineer at Minimum, you’ll play a key role in shaping our frontend architecture, user experience, and engineering best practices. You’ll work closely with our Frontend Engineer and Product Designer to create intuitive, high-performance user interfaces, while collaborating with the rest of the Product and Engineering team to ensure seamless integration with our platform. This is an opportunity to take ownership of frontend engineering decisions and help define how we build, maintain, and evolve our product.

You will:

• Work closely with Product and Design to build intuitive, user-friendly experiences that solve real customer problems.
• Architect and implement scalable, maintainable frontend solutions using modern frameworks and best practices.
• Take ownership of frontend engineering decisions, contributing to technical strategy and best practices.
• Ensure code quality and maintainability through testing, code reviews, and continuous refactoring.
• Stay up to date with the latest frontend technologies and advocate for best practices that enhance development speed and product quality.

About You

You should be someone who:

• Enjoys collaborating with Product Designers, Engineers, and other stakeholders to build customer-centric products.
• Is comfortable taking the lead on frontend decisions and working independently across the SDLC.

• Thrives in a fast-paced, early-stage startup environment.

Must-have Skills:

• 5+ years of professional experience in frontend development.
• Strong experience with React.
• Proficiency in TypeScript and modern JavaScript (ES6+).
• Experience working closely with Product Designers to implement high-quality UI.
• Experience with state management (e.g., Redux, React Query) and component-driven architecture.
• A solid understanding of frontend testing strategies (e.g., Jest, React Testing Library, Cypress).
• Comfortable working independently while collaborating effectively with engineers and product teams.

Nice-to-have Skills

• Experience with frontend architecture decisions in a growing startup.
• Familiarity with design systems and component libraries (e.g., Storybook).
• Experience with GraphQL, REST APIs, and data-heavy frontend applications.
• Previous experience working in B2B SaaS or enterprise software.
• Exposure to backend technologies (Python, Django, or similar) for better cross-functional collaboration.
• A passion for or previous exposure to Sustainability / Carbon footprinting concepts.

We're looking for brilliant people. If your experience doesn't quite match all of the points above, but you feel you have a lot to offer the team, we'd love to hear from you.
