Full Stack Engineer

London, 4x days per week in-office

Vega is looking for a Full Stack Developer to build features end to end across our platform from Java/Spring Boot services and APIs to React and Type Script interfaces – using AI tools as a core part of how they work and helping bring AI-powered capabilities into the product.

About Vega

Vega is transforming the way private markets operate. Alternative asset management is one of the most influential forces in the global economy, with over $20TN in assets today. Over the next five years, the industry is set to grow 3x, but GPs are facing challenges around their ability to handle the investment flows that are coming in. GPs have been completely underserved by innovation, particularly on the investor relations side.

Vega built the industry's first AI-native operating system, where all client work gets done – from the start of an investor's journey to its end. We are rethinking how work gets done in private markets from first principles: the opportunity is big, but it's also niche, high-stakes, and difficult to get right.

Who we are

We are still at the beginning of our journey. Vega was founded by former investors at Elliott and KKR, and built by talent from the world's leading technology and financial services firms – including Trade Republic, Revolut, Goldman Sachs, BCG, and more. We have raised $30M so far, with the backing of Apollo, Motive Partners, and 60+ senior executives from the industry.

Today, we have over $300B AUM and 30,000 users on the platform, and we have much more left to do.

How we do it

Vega is a fast-growing startup. We want to make this a career-accelerating place for people with the ambition to build something big. If the below sounds appealing, it could be for you:

We do not seek consensus. You will be expected to voice opinions and take initiative. Vega's best people do not wait to be told what to do before finding solutions to problems they have spotted.

We believe bureaucracy is the killer of progress. We are focused on creating the minimum viable process to operate with quality at speed.

We prioritise talent over tenure. There is no promise of progression without performance – we assess and reward people on impact above all else.

We iterate fast. We make decisions amid ambiguity and with imperfect information, and we strive to balance committing to a hypothesis with iterating at low ego.

We play to win. Expectations, intensity and ambition are very high, with every single colleague contributing to Vega's success. This often will not be a 9-5.

We know that this culture won't be for everyone, and we endeavour to make this clear from the beginning of the recruiting process out of respect for your time. Ask yourself whether the above sounds exciting to you in practice every day, and if it does, we would love to hear from you.

Who succeeds in this role

We look for people who match our ambition levels, and then raise it further.

In this role, you will:

Own problems from scoping through shipping and iteration, working directly with business and engineering teams to turn ideas into production features across the full stack
Use agentic coding tools such as Claude Code, Codex and Cursor as a core part of how you design, build, test and review software – and help shape how the team gets the most from them
Work with our AI engineers to integrate AI features into the platform – wiring agents, LLM-powered workflows and MCP integrations into services and user interfaces, including streaming responses and sensible guardrails
Build and maintain microservices using Java 21 and Spring Boot, contributing to an open architecture that integrates the many players in the private markets ecosystem
Define, develop and optimise RESTful APIs, owning the…
