The Role
We are building the operating system for restaurants of the future from the ground up. Your goal is to build high-leverage systems that help automate the industry and reduce manual work to zero. This isn’t a role for someone looking to coast. You’ll have ownership, visibility, and influence across the stack. Expect shipping to users every sprint then tighten them in the following sprints.
Why Now
Jelly’s profitable but product demand is outpacing us today. We’re investing in stronger foundations to unlock more velocity, but we’re stretched. Help us move faster, raise the bar, and shape how we build as we grow.
You’ll Work With

You might be a fit if:
- You turn big, messy problems into a working demo within two weeks.
- You jump in to unblock a teammate instead of letting them spin.
- You look out for new tools and share what works.
- You leave both code and process cleaner than you found them.
- You’ve stuck with at least one product for 3+ years and driven it forward.
- You’re looking for a long-term home where shipping fast and building well both matter.
What You’ll Get:
- Real ownership from day one
- £70–90k depending on experience
- Significant equity (1–2%) and long-term career upside
- A culture that values engineers, with protected ‘Engineer-Owned-Sprint’ for tech-debt
- 1-on-1 with founder; access to roadmaps
- 33 days holiday, London office (Old Street), Visa sponsorship available
- Fortnightly team dinners at customer restaurants
Minimum requirements:
- 4+ years commercial experience shipping and maintaining production-level software
- Typescript: deep understanding of both front-end and back-end usage
- Backend: proficiency in software design patterns
- Cloud provider: experience running live production workloads in the cloud
- Relational database: confident writing queries, designing schemas, and shipping DB changes without downtime
Bonus preferences:
- GraphQL: built and consumed APIs at scale
- Latest tooling: we use AI and computer vision to speed up internal data workflows
- Ownership mindset: scope, build, test, and ship without hand-holding
- Agile instincts: comfortable iterating fast and making smart tradeoffs
- Testing culture: experience writing effective, maintainable automated tests
Interview process:
- Stage 1: Quick intro call with founder (15min)
- Stage 2: Technical interview (2 hours) on a real problem
- Stage 3: Conversation with team + founder (2hrs)
