Software Developer

As a Software Developer II at Opus 2, you'll own features or small projects end-to-end, from planning through delivery and iteration. While you're a full stack developer, your main focus should be on front-end excellence, as one of your first major projects will center on delivering a delightful and engaging front-end experience. You'll partner closely with Product and Design, providing technical input to shape achievable, user-entered solutions. You'll bring strong engineering craft, mentor less experienced engineers, and begin to influence broader squad practices around quality, reliability, and delivery speed. You will be part of our Amsterdam office working directly with a small local team but collaborating closely with a larger engineering team in Edinburgh, UK, AI team in London, UK and the wider business functions globally. A great opportunity to apply AI to a defined and in demand set of customer needs at a company where over 50% of customers are already using AI in our existing workflows.

What you'll be doing

• Evaluate trade-offs of AI-driven solutions and collaborate with Product/Design/Tech Lead to ensure AI use supports user and business value.
• Share learnings about effective AI use with the squad.

What Success Looks Like

• You deliver features and small projects with minimal supervision and strong quality.
• You take initiative in solving technical and delivery problems.
• You provide valuable technical input in shaping roadmaps and user solutions.
• You mentor others, strengthening your squad's overall technical capability.

• Experience in observability tooling for distributed AI systems.
• Understanding of data ingestion and transformation pipelines supporting vector and knowledge graph stores.
• Proven ability to own feature delivery end-to-end.
