About Jelly
Jelly is rebuilding the operating system for food businesses from the ground up. Kitchens in Michelin stars, pubs, cafes and hotels still run core ops on pen & paper; we give them a modern operating system. 500+ sites use Jelly today and we’re profitable.
Why Now
Jelly’s profitable and demand is outpacing what we can ship. We’re investing in stronger foundations to unlock more velocity, but we’re stretched. This is the moment for you to help us move faster, raise the bar, and shape how we build as we grow.
The Mission
Take real ownership, work with the founder and engineering team to ship weekly, learn from users, and improve the product and the codebase as we scale.
You’ll Work With
- Founder (product)
- Engineers (shipping code)
- Part-time Designer (UI/UX)

You might be a fit if:
- You’ve shipped real things and dealt with their consequences
- You’ve worked in small teams and like solving problems end to end
- You know when to refactor and when to move on
- You care about users and outcomes more than abstractions
- You want to grow with a company, not just do a tour of duty
What You’ll Get:
- Real ownership from day one
- £70–90k depending on experience
- Significant equity (1–3 %) and long-term career upside
- A culture that values engineers, with protected time for cleanup and craft
- 1-on-1 with founder; access to roadmaps
- 33 days holiday, Hybrid London (Bank), Visa sponsorship available
- Fortnightly team dinners at customer restaurants
Minimum requirements:
- 4+ years commercial experience shipping and maintaining production-level software
- Typescript & React: deep understanding of both front-end and back-end usage
- AWS: experience running live production workloads (we use ECS, RDS, Lambda, SQS, VPC)
- GraphQL: built and consumed APIs at scale
- PostgreSQL: confident writing queries, designing schemas, and shipping DB changes without downtime
- Strong communication: able to collaborate clearly with non-technical team members
Bonus preferences:
- Latest tooling: we use AI and computer vision to speed up internal data workflows
- 2+ years in SaaS: ideally in products used by SMEs or operational teams
- Full ownership mindset: willing to 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)
