Behind the Code at Eedi: Where Mission Meets Machine Learning

What if your next backend system didn’t just process data – it helped over a million children finally “get” maths?

That’s the mission in this remote job at Eedi, a UK-based edtech startup using artificial intelligence and human insight to tackle one of education’s biggest problems: learning misconceptions in maths. Every year, thousands of students fall behind not because they’re lazy or disinterested, but because key concepts get missed – and no one spots it in time. Eedi changes that by delivering AI-powered diagnostics, personalised interventions, and real-time feedback loops to schools across the UK and beyond.

This is education technology with teeth – and the engineering challenge behind it is as meaningful as it is complex in this remote job.

See how Eedi transforms maths learning with AI-powered insights for teachers, students, and parents alike.

To scale that impact, we’re hiring. Right now, we’re looking for a senior-level candidate for a backend API .NET Engineer job – remote, UK-based. Someone who’s ready to own the core infrastructure that powers our AI systems and shapes how we deliver learning at scale.

You won’t be a cog in a sprint machine. You’ll be building the foundation for a product that genuinely improves lives – and working alongside a team that blends deep academic expertise, pragmatic engineering, and a relentless focus on outcomes.

If that sounds like your kind of problem set, keep reading.

Why We Exist – Fixing Maths, at Scale

At its heart, maths is a language. But when a student misses a word or two – a core concept or logic step – the whole subject can quickly become confusing, even intimidating. For millions of children worldwide, this is the daily reality. They fall behind not because they’re incapable, but because subtle misconceptions go undetected and snowball.

Eedi exists to fix that, and this remote job gives you the chance to play a key role.

We’ve built a platform that combines artificial intelligence, education technology, and cognitive science to pinpoint those hidden gaps – and then deliver just-in-time feedback to close them. With a blend of machine learning models and real classroom insight, Eedi helps teachers spot and address misconceptions before they become permanent roadblocks.

And it works.

Our backend systems play a critical role in that. From API endpoints that serve dynamic questions to infrastructure that processes millions of data points in real time, everything we build is designed to support personalised education at scale.

That’s why this backend API .NET Engineer remote job matters. It’s not just about writing code – it’s about creating the tools that help real learners overcome real problems.

At Eedi, we believe every child deserves the chance to succeed in maths. And we’re using engineering – powered by artificial intelligence and ethical machine learning – to make that happen.

Key Engineering Challenges We’re Tackling

Great education technology is invisible – it works seamlessly in the background, adapting to each student’s needs without disruption. But to build that? It takes serious engineering.

At Eedi, we’re creating the backend systems that power real-time learning diagnostics, scalable content delivery, and AI-driven feedback – all in one platform. It’s a blend of technical depth, architectural clarity, and product sensitivity.

Why Eedi puts pedagogy first – and how this approach makes their tech genuinely useful in classrooms.

This isn’t a standard CRUD app. You’ll be helping us build systems that:

• Ingest and process learner data in real time
• Connect seamlessly with machine learning models for misconception detection
• Serve dynamic, adaptive content via GraphQL and RESTful APIs
• Support integrations with schools, partners, and future B2B platforms
• Do all of this reliably, securely, and at scale

As our platform grows, we’re navigating challenges around data pipelines, low-latency architecture, and ethical use of AI in classrooms. In this remote job you’ll play a key role in defining and building the systems that make this possible.

Our stack is built on .NET Core and Azure – with a modern architecture that encourages developer ownership, CI/CD, and clean interfaces between microservices. And if you’ve got strong instincts for designing APIs and experience with cloud-native systems, you’ll fit right in.

Deep-dive into Eedi’s research engine – blending cognitive science, AI, and classroom reality to improve outcomes.

Joining us in this backend API .NET Engineer job means working with purpose, precision, and plenty of architectural input. You won’t just be coding features – you’ll be shaping the foundation that makes AI-powered personalised learning real.

The Backend API Engineer Role – Own the Core Infrastructure

Our Stack at a Glance

This is not a legacy maintenance gig. This is a hands-on, high-autonomy role for someone who wants to build from the ground up – and actually see their code shape learning outcomes across thousands of classrooms.

In this remote backend API Dotnet Engineer job you’ll be joining a small, sharp team of engineers who care about both craft and impact. You’ll help build, scale, and refine the backend systems that power our AI-driven maths education platform.

What You’ll Be Doing:

• Designing and developing robust Dotnet Core APIs to serve dynamic learning content
• Leading architecture discussions for our backend services
• Collaborating closely with frontend, data science, and product teams
• Integrating machine learning pipelines into our core services
• Maintaining high code quality through testing and CI/CD pipelines
• Monitoring, refining, and scaling our infrastructure in Azure Cloud

You’ll report directly to the Head of Engineering and work in a squad-based model for this remote job – cross-functional, low-ego, and built for speed. Engineers are involved from idea to implementation, with real input into product and UX decisions.

Our Tech Stack:

• Backend: Csharp, ASP.NET Core, GraphQL
• Infrastructure: Azure (App Services, Functions, Storage), Docker
• Data: PostgreSQL, Redis, RabbitMQ
• Tooling: GitHub, CI/CD, xUnit, Postman
• Frontend: React, Storybook (optional exposure if you want it)
