Job Description:

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 fully remote setup (or join us in our East London office if you like the buzz)
• 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)
• Work/life flexibility: work when and where you’re most productive
• Travel opportunities to meet clients (if you want them!)
• Minimal bureaucracy with maximum clarity — we aim to keep things simple, honest, and human

How We Hire

We keep the process simple, respectful, and fast:

• Intro chat (30 min) – Meet our Talent Partner
• Tech review – Share past work or a small take-home (your choice)
• Live coding / system design – With a senior engineer or our CTO
• Founder chat – Get to know us, and ask anything
• Offer ?
