Job Specifications

Senior Backend / Full Stack Engineer (Contract) – Integrations Team

Outside IR35 / B2B | Fully Remote

Evantis is partnering with a fast-moving tech company that’s expanding a newly formed integrations-focused engineering team, responsible for how external partners connect into their platform.

We’re looking for hands-on backend engineers who enjoy building and delivering real production systems — people who are comfortable owning features end to end rather than operating at a purely architectural level.

This is a greenfield scope, with a strong emphasis on delivery and implementation.

What you’ll be doing

Building backend services and APIs using Node.js and TypeScript
Designing and implementing partner integrations (REST APIs, webhooks, lightweight plugins)
Owning end-to-end flows including validation, queuing, retries, processing, and responses
Working with cloud-native services (GCP environment) to deliver scalable solutions
Collaborating with principals and product teams while remaining a builder-first IC
Operating in a startup-style environment where priorities can evolve week to week

What we’re looking for

Strong hands-on backend engineering experience (senior IC level)
Deep practical experience with Node.js, TypeScript, REST APIs
Comfortable explaining and delivering implementation detail, not just high-level design
Experience integrating with external systems or third-party APIs
Familiarity with cloud platforms and CI/CD pipelines
Exposure to CMS or partner integrations (WordPress, Shopify, Zapier, etc.) is a bonus, not a requirement
Enjoys working autonomously and shipping working software

Details

Location: Fully Remote (UK or EU timezone overlap)
Engagement: Outside IR35 / B2B
Start: January
Interview Process: Single-stage technical interview (whiteboard + implementation discussion)
