Job Title: Principal Engineer

Company Description: Openr – Azzurri Group-backed hospitality SaaS platform

Job Description:
As the most senior individual contributor, you will serve as the technical right hand to the Head of Engineering. You'll lead high-quality feature delivery across a serverless TypeScript stack, balancing technical debt with rapid scaling. This role is perfect for a hands-on architect ready to shape the infrastructure of a platform powering 1,500+ venues.

Location: London, UK

Why this role is remarkable:

• Significant impact as the senior technical lead for a platform that acts as the “single source of truth” for major hospitality groups like Stonegate and Azzurri.

• Strong financial backing from Azzurri Group, combining the stability of a major player with the agility and growth potential of a fast-scaling startup.

• Direct influence on architectural decisions in a modern, cloud-native environment with zero out-of-hours support and a collaborative engineering culture.

What you will do:

• Lead the development of complex, integration-heavy features using TypeScript, Node.js, and AWS Lambda to sync data across global delivery platforms and EPOS systems.

• Mentor a team of six engineers through code reviews, architectural guidance, and technical unblocking to maintain high delivery standards and system reliability.

• Partner with the Head of Engineering to define the technical roadmap, manage system dependencies, and translate complex product requirements into scalable serverless solutions.

The ideal candidate:

• Expert-level proficiency in TypeScript and Node.js with a proven track record of building and scaling event-driven architectures on AWS Lambda.

• Extensive experience with PostgreSQL and SQL database design, coupled with a strong understanding of modern frontend frameworks like React and React Query.

• Exceptional communication skills with the ability to navigate technical debt, mentor junior talent, and collaborate effectively with non-technical stakeholders in a hybrid environment.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
