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
Interested?
Send a short note with your background + links (GitHub/LinkedIn/portfolio) and we’ll set up a quick chat

Do you want to take part in vegan volunteering around your local area?
You can do that – right here at The Vegan Society.
We have an ever-growing Community Network of vegans just like you, who have a passion to volunteer and promote veganism where they live.
Every month, our Network choose from a range of outreach tasks. These could include town centre stalls, writing to a councillor or MP, sharing our campaigns on social media or contacting local businesses. You're in control of how much or how little you do.
As an Advocate, you will have a network of other Advocates and an Organiser in your area. Your Organiser will be your main point of contact. They will send you tasks every month and ask you to feed back on what you've completed and any positive outcomes.
Why do we need you to volunteer?
As the vegan community grows, veganism itself becomes better understood. We're finding that more people are looking to The Vegan Society to find out what being vegan is all about.
Local communities are starting to see the vegan movement as something real and something that’s happening in their area. More people are embracing a vegan lifestyle, which we welcome. From new businesses, to families, to councillors, many people need support. This could be with a range of topics: going vegan, finding correct information around a vegan diet, providing vegan options in their business, MPs listening to vegan constituents, and learning about our work.
Local issues are often unique and more varied than national issues. Our volunteers from local areas are vital! They enable us to share our messages and campaigns in an effective way. Research tells us that people are far more likely to trust information from a peer rather than an outside expert, so community volunteering vastly increases the impact of our campaigns.
Our network of committed local vegans across the country is growing! The Vegan Society organises various outreach activities to influence change in every level of society. There are a range of activities going on all the time, from general educational stalls at events to meeting with local policy influencers.
Advocates are a crucial voice in their own community. They ensure that our campaign messages are spread far and wide. They provide a strong vegan presence in local communities.
What does the Advocate role involve?
Being an Advocate for veganism with The Vegan Society will mean communicating with people in your local community. You'll share the benefits of a vegan lifestyle. You will form part of a local group, headed up by a local Organiser. The Organiser will feed back your collective efforts to staff. You will also be invited to our private Facebook group, for vegan socialising and ideas sharing.
You’ll stay in touch with the Organiser and bring your passion to tasks. Activities can range from staffing a stall to giving a talk at an employee event. It could also mean writing to a local newspaper or lobbying an MP.
Messaging can differ every month. Part of our mission statement is to ensure people can remain vegan, so you might focus on getting more vegan options available in local businesses. Or within our Live Vegan for Less campaign, you may share cheap vegan recipes to help people with the cost of living.
When acting as an Advocate, you will use The Vegan Society’s branding and messaging guidelines. Your local Organiser will guide you in doing this, as they hold physical resources and handbooks. You can report any issues and feedback you have to your Organiser. You can also contact staff if your Organiser isn't available or you have any problems.
What training and support is available?
You will be provided with a big welcome and full induction from your local Organiser. They will introduce you to the group and any actions that are ongoing. Any training and development will be provided via your Organiser, and you can also ask for specific training on any areas that you need some development in.
What skills would be useful in doing this role?
How much time do I need to invest?
For Advocates, we ask for people to engage in a minimum of four to six actions per year. An example of an action could be writing to an MP or holding a stall. But the more you can do, the better! On occasion, there may also be online meetings to plan for actions or provide training.

betterSoil is a sustainable start-up and a movement that is passionately committed to the health of our earth's soil.
We are currently losing around 10 million hectares of fertile soil worldwide. That's about 14 million football pitches. However, good soils are the source of more than 90% of our food. At the same time, the world's population will grow to 10 billion people by 2050. Food will therefore become scarce, especially high-quality food, as this depends on the quality of the soil. The effects of climate change are worsening the situation of soils because droughts and extreme rainfall are becoming more severe and more frequent. Current farming methods lead to high CO2 emissions, diseased soils produce low-quality food and biodiversity is rapidly declining, as around half of biodiversity lives in the soil.
Since 2020, betterSoil has been involved at European level, e.g. with an event with the EU Parliament and prominent supporters such as Prof. Dr Ernst Ulrich von Weizsäcker, Dr Franz Fischler (Former EU Commissioner for Agriculture) and Dr Peter Johnston (European Policy Centre) in a national and international context to improve soil quality for climate resilience and climate protection as well as the promotion of biodiversity and sustainable food production. Our way of working goes far beyond soil consulting. We combine local, indigenous knowledge with the latest science and offer practice-orientated betterSoil recipes for farmers. We also offer individual consultations for companies and organisations of all kinds. In this way, we create a comprehensive awareness of soil health that helps to position

• Creativity, reliability, and the ability to work independently in a remote team.
What You’ll Gain
• Be part of an international, mission-driven team reimagining soil as the foundation of a sustainable future.
