Senior Software Engineer / Full Stack Developer

Based either London (Remote working) or Budpest (Remote)

Salary - to attract the best

Brand new role available - growing HR tech innovation - SaaS

The Role We’re looking for a sharp, curious, and hands-on Senior Software Engineer who’s excited by AI, new technologies, and solving real-world problems at scale. You’ll be working across the entire product and software development lifecycle — from discovery and design, all the way through to deployment and ongoing performance.

You’ll own your work end-to-end, and have a high degree of autonomy as you help shape the future of our platform, working closely with product, customer success, and our clients. Key

Responsibilities

● Develop, test, and release new features and services on a regular cadence

● Build and maintain REST APIs and web services, with performance, reliability, and security top of mind

● Take part in product discussions and technical feasibility assessments with internal and external stakeholders

● Carry out thorough QA processes, including writing unit and integration tests

● Use Git, CI/CD pipelines, and cloud-native tooling to ship high-quality code fast

● Continuously explore new frameworks and tools – if there’s a better way, we’re all ears

● Help shape the engineering culture and processes as we scale

● One of the best services we’ve built? A Lambda-based Integrations Service that handles all interactions between our API and third-party integrations

About you

8+ years of full-stack development experience is a good starting point, but importantly - a personality and ability and willingness to interact with customers directly is critical here...

● A passion for the real-world applications of generative AI, coupled with fresh ideas on how to harness its potential to create meaningful impact.

● Experience working with MySQL (or similar SQL-based databases)

● Solid AWS or GCP DevOps experience — we don’t manage servers directly!

● Strong grasp of git workflows, CI/CD practices, and testing strategies

● Problem-solving mindset, attention to detail, and great communication skills

● Comfortable working independently and cross-functionally in a fast-paced startup

Nice to Have

● Experience building or working with GraphQL APIs

● Familiarity with React Native / Expo

● Exposure to NoSQL databases ● Understanding of git-flow (and how to survive it)
