Job Title: Lead Backend Engineer

Salary: £110,000 - £130,000

Company Description: Midnite - Series C fintech platform with $75M+ raised

Job Description:
Join Midnite as the technical lead for our greenfield AI & Back Office team. In this player-manager role, you will build the internal platform powering our global operations while driving practical AI integration across engineering workflows. You will lead three engineers to ship high-quality Python systems that redefine how our business operates daily.

Location: Remote, UK

Why this role is remarkable:

  • Lead a brand-new, greenfield function with total autonomy to shape technical architecture and AI experimentation from day one.

  • Work for a well-funded Series C startup backed by The Raine Group, shipping proprietary technology to production daily in a modern AWS environment.

  • Drive high-impact AI enablement, moving beyond chatbots to build production-grade LLM tooling that accelerates an entire engineering organization.

What you will do:

  • Architect and build the core backend systems for Midnite’s internal back office platform, focusing on configuration management and operational APIs.

  • Manage and mentor a small team of three fullstack and backend engineers, maintaining a high bar for code quality and professional growth.

  • Identify and prototype AI-powered improvements such as automated documentation, RAG pipelines, and intelligent alerting to reduce operational toil.

The ideal candidate:

  • 7+ years of experience in backend engineering with strong Python proficiency and a solid foundation in cloud infrastructure (AWS preferred).

  • Proven ability to lead or mentor engineers while remaining hands-on as an individual contributor in a fast-paced environment.

  • Practical experience integrating LLMs and AI APIs into production systems, with a pragmatic approach to building useful business tools.

We never post fake jobs

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.
