ABOUT THE ROLE

You'll build and own Salmon's Frontline Employees Database — the internal system that runs HR and operational processes for around 4,000 frontline employees.

WHAT YOU'LL DO

- Start with Frontline DB, which brings together employee and candidate profiles, access and account data, time-off information, shift planning, and selected operational results — with a backlog of initiatives across development, integrations, data mapping, documentation, and process improvement.

- Own solutions end to end: dig into the business need, clarify requirements with stakeholders, propose a practical approach, and turn it into a working MVP.

- Work directly with HR, Operations, People Partners, and Support, and over time extend scope into integrations with HiBob, Ashby, and other internal systems.

WHAT YOU'LL OWN

- Develop and improve PostgreSQL data structures for custom internal solutions.

- Design, build, and maintain automation and integration workflows in n8n.

- Build internal applications, forms, and user interfaces in Retool.

- Integrate HR and enterprise systems through REST APIs, webhooks, and other integration methods, with custom logic in Python and/or JavaScript.

- Test, troubleshoot, document, and maintain what you build — and handle internal support requests for existing tools and workflows (about 20% of the role).

- Grow MVP solutions into reliable internal products as processes and needs evolve.

WHAT MAKES YOU A STRONG FIT

- Confident SQL skills and experience with relational databases — you can query, validate, and interpret data independently.

- Hands-on experience with n8n, Make, or another low-code automation platform.

- Experience with Retool or another platform for building internal applications and forms.

- Working knowledge of Python and/or JavaScript for scripting and automation.

- Understanding of REST APIs, webhooks, and common integration patterns, plus a basic grasp of testing, debugging, and error handling.

- A proactive working style — you read incomplete requirements, make reasonable technical decisions independently, and know when to escalate — with good English for working with international stakeholders.
