Full job description

Job Summary

We are looking for a Founding Software Engineer to build a new SaaS platform for wholesale businesses covering inventory, purchasing, a B2B customer ordering portal, CRM and integrations with Xero, Shopify, Royal Mail and Amazon etc. You will be the first technical hire and will own the codebase. This is not a blank-page role: the architecture is designed and documented, a working database schema and tested pricing engine already exist, and a full product prototype has been validated with real wholesalers. Your job is to turn that foundation into a production system with paying customers, working directly with the founder and shaping the product as well as the code.

Duties

Build the core platform in TypeScript: a NestJS API and Next.js front end, backed by PostgreSQL and Redis, structured as a modular monolith (deliberately not microservices).
Implement the operational heart of the product: authentication and roles, product catalogue, sales orders with stock reservations, purchasing and goods receipt, and the pricing engine integration.
Develop the B2B customer ordering portal with customer-specific pricing, live stock availability and credit control.
Build the integration layer, starting with Xero, followed by Shopify, Royal Mail (Click & Drop) and Amazon SP-API etc.
Design and evolve the PostgreSQL schema, including row-level security for tenant isolation and an append-only stock ledger. Comfort with transactions and locking matters here.
Implement and document RESTful APIs (OpenAPI) used by both our own front ends and customer integrations.
Own deployment and operations on AWS using managed services, with CI/CD through GitHub Actions and infrastructure as code.
Write unit and integration tests as part of everyday work; integration tests run against a real Postgres database in CI.
Work directly with the founder to turn product decisions into working software, and push back when you think something in the plan is wrong.

Experience

Proven experience building and running production SaaS.
Strong TypeScript across the stack: Node.js on the back end (NestJS preferred) and React on the front end (Next.js preferred).
Genuine PostgreSQL depth: transactions, locking, indexing and ideally row-level security, not just ORM-level knowledge.
Experience deploying and operating systems on AWS (or equivalent cloud) including monitoring, migrations and incident handling.
Solid API design experience (REST/OpenAPI); experience integrating third-party platforms such as Xero, Shopify or Amazon is a strong plus.
Experience with inventory, ordering, ERP or e-commerce systems is desirable but not essential.
Familiarity with multi-tenant SaaS architecture is a strong advantage.
A testing habit: you write tests because that is how you work, and you treat a green CI pipeline as the gate for shipping.
Comfortable owning a codebase solo in an early-stage environment and managing your own priorities.

This role is a chance to build a product from the ground up without the usual blank-page risk: the groundwork is done, the market is real, and through our existing business we already have access to early customers.

To apply, send a CV and a short note about the most complex production system you have built and run, including what broke and what you would do differently. A link to code or a live product is worth more to us than a cover letter. No agencies, please.

Pay: £50,000.00-£65,000.00 per year
