Full job description

About us

StoneRise builds a multi-tenant ERP platform for the [construction / built environment] sector. It is a single product suite covering procurement, HR, commercial management, subcontractor payments, site management, health and safety, and training, used daily by teams running live projects.

You would be joining a mixed engineering team of onshore developers based in our London office and offshore developers working alongside us.

This is an office based role at our Kings Cross / Camden office, five days a week.

The role

We are looking for an intermediate developer to join our engineering team. You will work across the full stack, covering Next.js front ends, Fastify APIs, PostgreSQL and Prisma data models, and AWS Lambda background jobs.

This is a hands on role for someone comfortable owning a feature from database schema through to UI. You will get plenty of ownership, code review from senior engineers, and exposure to a broad stack.

As we work across time zones, clear written communication is important. That means good pull request descriptions, clear tickets, and flagging blockers early.

What you will be working on

Building features across our Next.js applications (admin shell, procurement, HR, commercial) using the App Router, React and our shared component library
Designing and building REST endpoints in our Fastify microservices with typed request and response schemas
Modelling data in PostgreSQL via Prisma, extending a large multi-tenant schema
Writing AWS Lambda functions for background processing, including invoice OCR and matching, purchase order validation, quotation matching, inbound email processing, accounting sync, and scheduled notifications
Integrating third party services including Stripe for billing, accounting systems, Microsoft Graph, Pusher for real time updates, and Twilio
Working on AI assisted features such as document data extraction and invoice matching
Writing unit, integration and end to end tests in Jest
Reviewing code from across the team and contributing to the shared internal packages used throughout the platform

Back end

Next.js API routes as a BFF layer
JWT based authentication with role and permission based authorisation
Multi-tenant architecture with tenant level data isolation

Data and infrastructure

PostgreSQL
Prisma ORM
Redis (ioredis)
BullMQ for job queues
AWS Lambda, S3, SQS, SNS, DynamoDB, CloudWatch, CloudFront
LocalStack and Docker for local development

AI and integrations

Quality and monitoring

Jest for unit, integration, end to end, performance and security tests

Structured logging
OpenAPI and Apidog for API documentation

What we are looking for

Essential

2 to 4 years of commercial software development experience
Strong TypeScript and JavaScript
Solid React experience, and experience with Next.js or a similar SSR framework
Experience building Node.js back end services and REST APIs
Working knowledge of relational databases and SQL, ideally with an ORM such as Prisma, TypeORM or Drizzle
Comfortable with Git, pull requests and code review
Able to write tests for your own work
Clear communicator in writing as well as in person, as you will be working daily with colleagues in other time zones
Able to work full-time from our Kings Cross / Camden office

Desirable

Strong understanding and experience using AI assisted coding such as Cursor
Fastify, Express or NestJS
AWS services, particularly Lambda, S3 and SQS
Monorepo tooling such as Turborepo or Nx, or Yarn and pnpm workspaces
Redis, message queues or other background job systems
Tailwind CSS
Multi-tenant SaaS
Working with LLM APIs or AI assisted product features
CI/CD pipelines and GitHub Actions
Experience working in a distributed or partly offshore team
Exposure to ERP, finance or construction software

What we offer

£40,000 to £50,000 depending on experience
Central London office in Kings Cross / Camden
20 days annual leave + public holidays + company Christmas/New Year shut down
Company pension scheme
Ownership of features from design through to production
Broad exposure across front end, back end, cloud infrastructure and AI features
Mentoring from senior engineers and a clear path to senior
