Senior technical lead volunteer roles in Leeds

Unify is building a social impact platform that helps get direct, practical support to people who need it most — with dignity, transparency, and real-world usability at the core.

We’re looking for a Senior Developer / Tech Lead (Volunteer) to guide the build, unblock the team, and help us ship a solid, scalable product. This is a light commitment (2–5 hours per week), but a high-leverage role: you’ll be working closely alongside the founders and our Product Manager.

What you’ll do (2–5 hrs/week)

• Lead engineering direction: keep the build clean, pragmatic, and shippable.

• Review PRs and raise code quality (architecture, security, performance, maintainability).

• Help prioritise technical work with the founders + Product Manager.

• Support and mentor a small volunteer/dev team (light-touch guidance, not heavy management).

• Set up or improve engineering foundations (CI/CD, environments, observability, release process).

• Identify risk early (security, data handling, scalability) and propose solutions.

What we’re building

• A production product with real users and real-world constraints.

• A platform where trust, safety, and reliability matter as much as features.

Tech stack

MERN stack

• MongoDB (database)

• Express.js (backend framework)

• React (frontend)

• Node.js (runtime / API layer)

What we’re looking for

• Senior-level software engineering experience (ideally with leading small teams or acting as tech lead).

• Strong product sense: you can balance “build it right” with “ship it”.

• Comfortable in ambiguous, early-stage environments.

• Solid judgement around security, data handling, and best practices.

• A collaborative communicator who can keep things calm and moving.

Nice to have (not required)

• Experience with marketplaces, payments, identity/verification flows, or credit/voucher systems.

• Experience setting up CI/CD, testing strategy, and deployment pipelines for MERN apps.

• Previous work in startups, charities, civic tech, or social impact.

Why join (and what you’ll get)

• Real ownership and influence — your decisions shape the product.

• Work directly with the founders + Product Manager.

• A mission-led build where shipping matters and the work is tangible.

• Flexibility: async-first, lightweight weekly rhythm.

Time + format

• Volunteer: 2–5 hours per week

• Remote / hybrid (where relevant)

• Async-first with a short weekly check-in
