WE ARE:

Adaptive is a product-led financial technology company with deep expertise in capital, commodity, and digital markets.

What you will do:

• Analyse, design, discuss, and develop distributed systems based on replicated state machines.

• Write clean, efficient, maintainable, and self-documenting Java code.





• Design and evolve messaging protocols and software libraries.

• Troubleshoot and debug Java applications and distributed systems.

• Apply testing, benchmarking, measurement, and profiling to improve correctness and performance.

• Participate in code reviews, pairing, and technical discussions to raise the quality of our work.

• Contribute to product decisions, not just task execution.

• Keep up to date with relevant software engineering technologies and practices.

• Communicate technical decisions and priorities clearly to technical and non-technical stakeholders.

What you will bring:

• Experience designing, building, debugging, and operating distributed systems.
