Software Engineering Team Lead

Company: Harrington Starr
Apply for the Software Engineering Team Lead
Location: Greater London
Job Description:

This is an opportunity to step into a hands‑on technical leadership role within a growing backend engineering team. The company is at a natural inflection point: the engineering group is expanding from 6 to 8 engineers, and there’s a clear need to introduce structure, mentorship, and delivery ownership — without losing technical momentum.

The role suits a senior backend engineer who enjoys leading by example, staying close to the codebase, and gradually taking ownership of team leadership and delivery.

This is not a people‑only management role. Expect an ~80/20 split between hands‑on engineering and leadership responsibilities.

The Role

  • Act as the technical lead for backend development, contributing directly to architecture and feature delivery
  • Provide day‑to‑day mentorship and technical guidance to backend engineers
  • Introduce clearer reporting lines, ownership, and delivery structure as the team scales
  • Partner closely with the CTO, gradually taking on leadership responsibilities currently consuming senior leadership time
  • Own the delivery of backend projects, with responsibility for execution and technical quality
  • Support future team growth, including hiring, onboarding, and longer‑term team design

Team & Structure

  • Current team: 6 engineers, scaling to 8 in the near term
  • Planned split into focused teams, including a dedicated data pipeline / backend platform group
  • This role becomes the primary technical and delivery owner for one of those areas
  • Acts as a key bridge between engineers and senior leadership

What They’re Looking For

  • 7+ years of backend engineering experience
  • Strong hands‑on backend expertise, ideally in Python
  • Proven experience designing and maintaining production backend systems
  • Comfortable mentoring engineers and acting as a technical authority
  • Experience (or strong interest) in taking on people leadership responsibilities
  • Exposure to financial services is a strong plus (security, change management, regulated environments)
  • Pragmatic, delivery‑focused mindset — someone who gets things shipped

Why This Role Stands Out

  • Genuine hands‑on leadership role — not management theatre
  • Clear trust from the CTO to take ownership and step up
  • Opportunity to shape team structure, culture, and delivery practices
  • Real influence over architecture and backend direction
  • Competitive salary around £100k, depending on experience
