By applying first principle approach, we understood that the Foodservice Industry - folks who prepare food outside of the home - is the key to unlocking the food system we want.


Since raising seed funding fromTier 1 venture investors, including those that put first monies into Revolut, Transferwise and Just Eat, we’ve reachedprofitabilitywith a10x growthin our customer base. Thousands of chefs, operators and owners across 500+ food businesses rely on us every single day.


This is your opportunity to join our tight-knit team at this most impactful stage, where your impact will be magnified and your ambitions scaled globally.


The Company


Today, from Michelin-starred restaurants to your neighbourhood cafes,pen & paper and spreadsheets still rules over core operations -from costing menus, checking inventory to managing supplies. These operations are hidden from consumers’ eyes in what’s known as the Back-of-House, the beating heart of any food businesses.


While the Front-of-house - think point of sale, bookings, and food delivery - has attracted billions in investment, it fails to cope with core operations in the back. That’s where Jelly begins.


We are building a new system from the ground up for the Back-of-House - to change everything.


The Role


We’re looking for a senior-levelFounding Backend Engineerto tackle complex data challenges never before identified - challenges that are foundational to our vision of a new food system. These arise from a fragmented, complex industry handling billions of daily transactions without standardisation of data. You’ll harness cutting-edge technologies - from computer vision to LLMs, or any other novel approach you devise - to deliver transformative solutions.


You’ll have autonomy and influence in shaping a product for one of the world’s largest industries, working with a small, tight-knit, and highly supportive team. Strong communication skills are essential, as you’ll have visibility across all parts of the business.


While your primary focus is backend, we value flexibility in bug-fixing and building simple React components when needed.


Hard requirements

  • Proficient in TypeScript and NodeJS.
  • Can build and maintain AWS solutions with services including ECS, Lambda and RDS.
  • Strong understanding of GraphQL and performance optimisation.
  • Expertise with relational databases, including performance analysis and optimisation.
  • Ability to create simple React components and fix UI bugs.
  • Interest in AI technologies and some experience (including side projects) working with AI APIs.


Desirable requirements

  • Experience with PostgreSQL, triggers and stored procedures.
  • Experience with strictly typed languages such as GoLang.
  • Experience with NoSQL and big data.
  • Experience with Nexus GraphQL.
  • Experience implementing AI APIs in an ETL pipeline or similar.


Compensation

  • Salary £70-90k, sponsor license available.
  • Significant equity options reflecting the importance of this role, more than you would find elsewhere.
  • 33 days of paid leave per year (25 holidays + 8 bank holidays).


Perks

  • Flexible: we prioritise in-office work for fostering collaboration, with most of our team in our Bank office 3 days a week, balanced with the freedom to work from home as needed.
  • Dedicated one-to-one coaching sessions.
  • Fortnightly social dinners at our customer restaurants.


Interview Process

  • Stage 1: Phone call with CEO (15min)
  • Stage 2: Take-home test (approx. 2 hours). Demonstrate your technical skills with a relevant real-world scenario
  • Stage 3: Technical interview (2 hours). Collaborate with our team to review your take-home test and discuss solutions
  • Stage 4: Leadership interview (1 hour)
