Senior Software Engineer

Join a mission-driven, people-first startup building better ways for global brands to work with global retailers.

At VST , we’re on a mission to transform how massive brands like Mars, Coca-Cola, and Unilever collaborate with retailers, through smart tech and better data. We’re a venture-backed startup with solid foundations and a lot of ambition — and we’re growing our team.

We’re now looking for a Senior Full Stack Engineer with strong TypeScript experience to join our collaborative, curious, and kind team. You’ll work across the full stack to build products that customers actually love — shipping fast, thinking deeply, and owning your craft.

Diversity & Belonging at VST

We believe building great software starts with diverse thinking, lived experiences, and inclusive culture . We’re proud to be building a team where different perspectives aren’t just welcomed — they’re essential. Whether you’ve followed a traditional path or not, we encourage people of all backgrounds, identities, and communities to apply.

🧠 What You'll Work On

We’re building a powerful enterprise web app powered by big, proprietary datasets. Some things you might tackle in your first year:

• Scale and refine our product to serve large enterprise users
• Contribute to customer-facing features using React, Node.js, GraphQL, and Postgres
• Improve performance and reliability across our data-heavy frontend
• Join user interviews and work closely with design to make thoughtful, human-focused UX decisions
• Take part in shaping the engineering culture, practices, and mentorship
• Explore opportunities to expand your impact into areas like infrastructure, security, and hiring

👣 What Your First Year Might Look Like

• 30 Days : You’ve shipped your first changes, paired with the team, and contributed to real customer impact.
• 60 Days : You’re leading initiatives, jumping into user interviews, and making smart suggestions to level up our stack and practices.
• 90 Days : You’ve delivered major features, participated in architectural decisions, and helped interview future teammates.
• 6–12 Months : You’ve owned big, business-critical projects, mentored others, and become a cultural leader in the team.

✅ What We’re Looking For

We’re open-minded about your background — whether you've worked in startups, agencies, or enterprise. What matters to us is that you:

• Are strong in full stack TypeScript , with real-world experience in React and Node.js
• Are comfortable in fast-moving, semi-structured environments
• Care about the details — from data modeling and testing to UI polish and user experience
• Can empathise with customers , not just code for them
• Communicate clearly and collaborate across disciplines
• Have a broad sense of ownership: you ship, test, debug, and iterate

🛠️ Our Stack

• Frontend : React, TypeScript, Effect-Rx, Styled Components, Storybook, Apollo GraphQL
• Backend : Node.js, Effect-TS, Postgres (Prisma), Redis, Snowflake,
• Infra : Docker, Pulumi, Kubernetes (Digital Ocean), CI/CD (GitHub Actions), Netlify
• Tools : Linear, Slack, Notion

💼 What You’ll Get

• Autonomy + ownership in a fast-growing product team
• A hybrid setup remote ( join us in our East London)
• A clear growth path with opportunities to lead projects and shape the product roadmap
• A great comp package :
• Competitive salary
• End-of-year bonus
• Share options with fair terms
• Sales referral bonus
• Top-tier equipment (M-series MBP or whatever helps you do your best work)
• We’re currently hiring for this role based in London, with 2–3 days a week in the office (Old Street) and flexibility around that.
• Travel opportunities to meet clients (if you want them!)
• Minimal bureaucracy with maximum clarity — we aim to keep things simple, honest, and human
