Role

Who you are

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

What the job involves

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
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
️ 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

Our take

Virtual Store Trials builds data products that help retailers and brands make faster, smarter decisions at the shelf - and win the shoppers.

Its tools turn overlooked planogram data into real visibility, insight, and action. CPGs use VST to optimise in-store strategy and prove performance. Meanwhile, retailers use it to monetise data, improve execution, and unlock new value, without slowing down operations.

From rapid shelf testing with thousands of real shoppers to a planogram platform used by some of the world's biggest grocers, VST is helping both sides move with proof (not guesswork) and make the shelf work harder.
