Job Title:

Software Engineer (Data)

ASAP

Bristol/Hybrid (At least 2 days a week in-office)

Tumelo's mission is to empower shareholder democracy with technology that supports impactful stewardship. Our technology allows fund managers and investment platforms to provide pass-through voting functionality to our clients, with powerful reporting tools to support the production of regulatory and client reports. Our products empower asset owners to engage with their voting rights and provide them with the tools and knowledge to steward their assets effectively.

Tumelo is committed to building an inclusive, diverse and equitable culture based on the principles of high trust, autonomy, empowerment and psychological safety. We take inspiration from our company values - daring, nimble, mission driven, empowered and supportive. We all strive to represent these values in the way we work with our colleagues and external stakeholders alike.

Our engineering team is focused on building, enhancing, and scaling Proxy Sphere – our industry leading pass-through voting SaaS product, currently serving some of the largest investment firms in the world. Alongside this, we are also building a new AI platform for shareholder‑voting research and recommendations, to enable stewardship teams to aggregate data and produce voting recommendations at scale.

As an engineering function, we are deeply committed to the principles of Dev Ops, keeping engineers close to the things they build and release. This investment in automation enables the engineering team to safely release code multiple times per day.

We work in a highly collaborative culture and actively encourage engineers to share ideas, pair and collaborate. If you’d like to be part of a team with a progressive culture and modern engineering practices, this could be the role for you.

This is an exciting opportunity to get stuck in at a fast‑paced, tech‑focused, impact‑driven start‑up.

As a Software Engineer, you will have the opportunity to work autonomously while collaborating closely with product, design, and operational teams to deliver high‑quality solutions.

Some recent examples of work include:

• Creating a bespoke workflow‑management and vote‑submission system to support the scaling of our internal processes to match demand.
• Prototyping new AI‑based solutions to help support stewardship teams.
• Refactoring legacy services onto a new stack to improve developer experience and increase engineering velocity.

We have a culture of openness, support and giving feedback. As an engineering team, we spend one day each month learning new things together to maintain our skills and explore new ideas.

To be successful in this role, you'll bring:

• A desire to learn new things and continuously improve
• A hands‑on approach and willingness to tackle complex engineering challenges
• Experience working as part of a team on a high‑quality software stack
• A strong understanding of software engineering principles and computer science fundamentals, applied to building scalable, efficient, and maintainable systems
• Experience writing production code in Go, Python or Type Script
• A strong interest in writing testable code and enthusiasm for adopting an automation‑first approach (CI/CD)
• A good understanding of event‑driven systems
• Designing, implementing and maintaining automated data pipelines using AWS
• Experience designing and building RESTful APIs
• Familiarity with IaC tools such as Terraform
• Previous experience working in a scale‑up environment

• Salary: £50k - £65k, dependent on experience
• Generous company share scheme – We are all owners of Tumelo and beneficiaries of our collective success
• Private health insurance – Full coverage via AXA, also including 24/7 private GP access, dental, optical, mental health support, physio and other benefits
