About Bank.Green
Since the Paris Agreement, global banks have poured a staggering $7.9 trillion into the fossil fuel industry. Bank.Green exists to change that.
We build tools that help people understand how their bank finances climate change, and what they can do about it, whether that’s switching to genuinely greener alternatives or pushing their existing bank to improve. To date, our bank-checking tool has been used 500,000+ times globally and has helped influence at least £25 million in customer deposits toward banks financing a cleaner future.
Through transparency, technology, and public engagement, we aim to redefine the role of banks in the climate transition.
The Role
We’re looking for an experienced engineer to act as a technical steward for the Bank.Green website, our primary public-facing platform, working alongside another senior engineer already on the project. Technical decisions are made in a collaborative, consensus-driven way, rather than top-down.
The site is transitioning to Astro, with a React-based frontend, and is deployed via Cloudflare. Content is managed via Prismic as a headless CMS, with data coming from internal GraphQL and REST APIs.
The platform serves roughly 5,000 pages, the majority of which are repeatable, programmatically generated bank profile pages built from shared templates and structured data. As a result, performance, caching, SEO, and build efficiency are key concerns.
This is a hands-on but flexible role, suited to someone who enjoys maintaining and improving real-world infrastructure that thousands of people rely on.
What you’d be working on
-
Building and shipping new frontend features that improve how users understand and act on bank climate data
-
Maintaining and improving the Astro/React codebase with a focus on clarity, performance, and long-term maintainability
-
Improving build performance, caching strategy, and CDN efficiency to keep the site fast and cost-effective at scale
-
Collaborating on architectural and technical decisions with the other senior engineer
-
Reviewing and contributing pull requests, and helping establish sensible frontend and deployment patterns
Ways we work
- Fully remote and asynchronous
- Communication via Slack, Linear, and occasional calls (MS365)
- Pragmatic, low-process, mission-driven team
- Strong bias toward maintainable code and real-world impact
Commitment
This is an unpaid, volunteer role.
- Roughly 7–10 hours per week, flexible
- We’re looking for a longer-term engagement (around 6 months or more) to provide continuity and stewardship
What we’re looking for
- Required: A portfolio, GitHub profile, or equivalent code samples demonstrating real-world frontend or full-stack work
- Experience as a frontend or full-stack engineer at a mid-to-senior level
- Strong JavaScript fundamentals
- Experience with React and modern frontend tooling
- Familiarity with Astro, or strong interest in content-first frameworks (Next.js, Nuxt, Gatsby, etc.)
- Comfort reviewing code and guiding less experienced developers
- Experience working asynchronously with distributed teams
- Familiarity with Git-based workflows and Agile-style tools
- Genuine interest in climate action and environmental accountability
At Bank.Green, our mission is to shift financial institutions towards greener lending practices by empowering their customers to advocate for change.

ENGINEERS/MAKERS
Across the UK, our 60+ local branches help disabled people live the lives they choose. Our network of skilled volunteers respond to thousands of requests each year to design and make customised equipment free of charge.
Our Engineer/Maker volunteers are at the very heart of what our local branches do. They use their practical skills and creativity to help people with disabilities live fuller and more independent lives.
What the role involves
This is a varied role where local need shapes what you’ll be working on, but it often includes:
• Designing and making pieces of equipment for individuals with specific needs
• Using your practical skills working with metal, wood, plastic, or electronics (or a combination of them)
• Attending a monthly meeting of the local branch.
We can support you to develop the skills you need for this role, and there’s an induction that covers all the areas above. You’ll also have chance to discuss your role and any additional needs with us.
What you’ll need for this role
Essential
• Practical experience in working with one of the above materials
• Comfortable working with people, listening to them and understanding their needs
• Able to apply our risk management system
• Able to apply disability, equality, and inclusion practices
• Able to keep people’s personal details safe
• Willing to follow REMAP policies and procedures and a commitment to our values
Desirable
• Access to your own tools and workshop (or can access these)
• Able to drive or have good transport links
You’ll also need to complete the induction checklist, as well as a DBS check and reference check.
Where will I volunteer?
This role is largely home based, but will generally also involve visiting clients out in the community. Your local branches hold in-person meetings once a month or so.
Time commitment
This varies quite a lot depending on which cases come in, how complex they are and whether they fit your skills and experience, but it’s essentially a flexible role and there are no set hours.
Why volunteer
When you volunteer with us, you join a community of committed people with a passion for helping to improve the lives of others. We’re a volunteer led organisation and we couldn’t do what we do without your hard work, skills and commitment.
N.B. We’ll reimburse any out-of-pocket expenses during your time with us.
REMAP exists to improve the quality of life for people who experience short or long-term disability through infirmity, illness or ageing.
The client requests no contact from agencies or media sales.
