Senior developer volunteer roles
How's your job search on our site?
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

Trees for Cities
Salary: Voluntary role, reasonable expenses reimbursed
Location: London with flexibility
Closing Date: 11 March 2026
Trees for Cities is an independent national charity that empowers people to plant and care for trees in towns and cities, targeting places where they have the greatest impact for people and nature. Through trees, we connect people to nature, enrich lives and create leafy, liveable places for today and future generations. In a world facing unprecedented threats from climate change, biodiversity loss and disconnection from nature, our work has never been more urgent.
Since 1993, Trees for Cities has engaged 260,000 people to plant and care for almost 2 million trees across 100 urban areas in the UK and overseas. We are proud to operate at the intersection of social and environmental justice, focusing on communities with the least access to green space and the benefits it brings. To deepen this work, we have developed a new five-year strategy (2025–2030) with the goal of creating a Movement for Urban Trees and Tree Equity. As we enter this ambitious new strategic phase, the new Chair will play a leading role in overseeing its successful embedding and impact.
This is a rare opportunity to lead the Board of a dynamic, growing charity at a pivotal moment. Our Trustees are recruited for their diverse skills and perspectives, and we are proud of our strong governance practices and healthy Board culture. Together, we provide constructive challenge and meaningful support to the executive team, guided by the organisational values that sit at the heart of how we work. We are seeking an exceptional individual to become our next Chair, continuing this work, offering strategic leadership and robust governance to ensure Trees for Cities continues to thrive and grow in impact.
You will bring Board-level experience, including as a Chair, Vice Chair and/or Trustee/Non-Executive Director, and a proven ability to chair Board or committee meetings effectively. With strategic vision and the confidence to navigate complexity, you will demonstrate excellent communication and interpersonal skills, build consensus and manage diverse perspectives. You will bring a supportive and empowering approach, with a coaching style of leadership that empowers and enables others to thrive. Experience in the environmental, sustainability or urban greening sectors is desirable but not essential; what matters most is your ability to lead with integrity, inspire others and drive impact.
We want our Board to reflect the diversity of the communities we serve and particularly welcome applications from individuals from Black, Asian or other minority ethnic backgrounds, disabled people, and those with lived experience of environmental or social injustice. If you are motivated to help shape our next chapter and bring the leadership and experience to guide our ambition, we encourage you to apply.
