About Roots Academy. 

Roots Academy’s Vision.

A generation of young Muslims who embody and promote a God-centred way of life.

At Roots Academy, we’ve built a learning experience that’s changing the lives of the ummah’s future leaders, change-makers and visionaries. Our Mission is to deliver a structured and transformative education in the Essentials of Islam in a way that lowers barriers to access, develops a deep certainty, and inspires action.

Why Does Roots Academy Exist?

Crisis of Faith: 1 in 4 young Muslims are leaving the religion due to various factors, primarily the pervasive anti-religious content and temptations they encounter online and offline. 

Roots Academy exists to bridge this gap by providing a structured and transformative Islamic education that speaks directly to the needs and challenges of young Muslims today, delivered in an engaging and accessible form that removes barriers to access and provokes thought and action.

Role Summary.

We’re looking for a Data Engineer to help build, maintain, and scale Roots Academy’s data infrastructure. You’ll take ownership of key data pipelines, working closely with the data lead and collaborate with teams across Digital Platforms, Marketing, Fundraising, and Operations to ensure our data is reliable, well structured, and useful for decision making. Your work will directly support how we measure student transformation, programme impact, and organisational performance at every level.

Beyond this, you’ll contribute to the design of our data architecture, helping shape how data flows from source systems into the database. You’ll also support management of our GCP environment (e.g. BigQuery datasets, IAM, performance), ensuring the platform remains clean, scalable, and secure as Roots grows.

Key tasks

• Design, build and maintain data pipelines (e.g. from Firebase/Firestore, Google Drive/GCS, APIs into BigQuery)

• Contribute to Data Architecture design

• Manage & optimise datasets, and improve existing workflows (e.g. GitHub Actions, scheduled jobs, transformations)

• Support GCP platform management (permissions, dataset structure, service accounts, cost awareness)

• Improve documentation, data quality checks, and overall reliability of the data stack

What we’re looking for

• Experience with Python, and Data Engineering concepts

• Experience with SQL and data modelling concepts 

• Comfortable using Git and working with structured repositories

• Understanding of data pipeline concepts (batch processing, transformations, schema design)

• Able to work independently with clear task ownership

Desirable:

• Experience with GCP (BigQuery, IAM, Cloud Storage, service accounts)

• Familiarity with CI/CD workflows (e.g. GitHub Actions)

• Interest in impact measurement or education sector work

What we have to offer

• Be part of a team of 100+ dedicated volunteers across the UK, Ireland, Canada, US, UAE and Australia.

• Receive continuous rewards for those that seek Islamic knowledge from the Roots platform. 

• Be a part of a growing organisation that aims to revive and educate Muslims from a grassroots perspective.

• Receive in-house tarbiyah sessions to develop your deen. 

Please note this is an unpaid volunteer position. 

Volunteers are entitled to claim expenses incurred for food, travel and equipment, in line with our Expenses policy. 

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
