Job description

Job Description

Profitable VC‑backed SMB SaaS Startup | 1–2 % equity | UK visa sponsor | Build core product used by 500+ restaurants

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

JJ (Founder)

Robert & Dol (Engineers)
Raul (Part-time Designer)
Abbie (Customer Success)

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)

Apply here or DM me (JJ) on WhatsApp +447855553652 with a real data or system tradeoff you’ve made under pressure and what you’d do differently now.
