Job Description

Tech Lead | Android / Embedded Devices | C# / .NET MAUI | Hands-On + People Leadership | REMOTE

Salary:£90,000 + excellent benefits

Contract:Permanent

Start:ASAP (4 weeks notice periods maximum for this one!)

Working Model:Fully Remote

Location:UK

Eligibility:No sponsorship available. You must hold ILR or a British passport (role is subject to background checks) (Non-Negotiable)

?? Non-Negotiables - Please only apply if you have ALL of the following ??

Core Technologies:

  • Strong, production C# and .NET (7+) - not hobby-level
  • .NET MAUI for Android (or strong Xamarin / native Android and ready to move to MAUI)
  • Android platform development: activities/intents, lifecycle, background execution limits, device-owner APIs, MDM/EMM concepts
  • Hands-on device / hardware integration (scanners, imagers, card readers, printers, serial, GPS)

Environment:

  • Proven ownership of a delivery team's outcomes - sprint commitments, quality, operational health, not just your own tickets
  • Real people leadership - substantive 1-2-1s, developmental feedback, hiring input
  • On-call and incident ownership taken through to resolution, not handed off at first sign of difficulty
  • Comfortable in a regulated, high-throughput product environment
  • Honest, early risk communication as a habit, not an exception

Key Skills:

  • Messaging and comms: MQTT (pub/sub), HTTP clients, offline/online state handling
  • Logging and observability: log4net today, moving to OpenTelemetry / OTLP and structured logging
  • Native interop: JNI / Android binding libraries, P/Invoke against native libraries
  • Data and config: SQLite, XML-based configuration, key-value stores
  • Sound day-to-day technical judgement without escalating every decision
  • UK hours with high-level written and spoken English

Role Overview

We're partnered on an exclusive Tech Lead search with an established, market-leading business operating mission-critical devices deployed at national scale in a regulated, high-volume payments environment.

This is a genuine leadership seat, not a title in waiting. You'll lead a single delivery team of around 5 to 8 engineers (including embedded QA), own its delivery end to end, and grow every person in it. You'll stay technically credible in your domain, run the ceremonies that actually produce outcomes, and represent your team honestly upward. If you want deep technical work with zero people accountability, this isn't the one - and that's the point.

Key Responsibilities

  • Own your team's delivery: sprint and quarterly commitments, with risk surfaced early and honestly
  • Break complex features into team-sized work and run standups, planning, and retrospectives that produce real outcomes
  • Manage capacity properly - explicit space for tech debt, not an invisible tax
  • Lead people: regular 1-2-1s, honest development conversations, and hiring against a competency matrix
  • Own operational health: your team's on-call rota, incidents in your domain owned to resolution
  • Make sound day-to-day technical calls and capture the significant ones as ADRs
  • Partner closely with Product on what your team is committing to and why
  • Escalate cross-team risk and capacity conflicts before they become a miss

Nice to Have

  • Payments exposure: EMV, contactless, and an appreciation of the compliance surface (PCI-DSS, key management)
  • Matrix-organisation experience - adopting standards set by roles you don't manage
  • Azure DevOps for backlog and pipeline tooling
  • Regulated-environment experience (financial services, transport, healthcare)
  • Rust and/or Python, or a genuine willingness to learn them
  • Leading a team through organisational or structural change without stalling delivery

If you tick every box above, hold ILR or a British passport, and can start ASAP, we'd love to hear from you.
