Are you ready to take on complex, real-time, large-scale challenges and shape the future of an innovative AI powered platform already being scaled to extremely large corporate clients e.g. Deloitte and Legal and General.
We’re looking for aStaff Software Engineerto lead the development of features that handle tens of thousands of requests per second, all while solving intricate architectural problems.
The Company
This cutting-edge platform enables thousands ofparticipants to come together in a collaborative, single session, offering dynamic breakout rooms and AI driven real-time transcription services.
The Role
As aStaff Software Engineer, you’ll take full ownership of architecture and implementation, transitioning prototypes into scalable,event-drivenproduction-ready systems. You won’t be just picking up tickets – you’ll be at the forefront of driving architectural vision and building high-performance distributed systems. This is an opportunity to work in a high-autonomy environment where you’ll collaborate closely with product managers, UX designers, and clients to deliver tailored solutions.

Why This Role Stands Out:
- Architect event-driven systems from the ground up: high degree of ownership, system design and implementation.
- Tackle high-scale problems: Build systems capable of processing tens of thousands of real-time requests per second.
- Innovate: Lead the evolution of a real-time communication platform used by thousands globally.
- Growth opportunities: Play a key role in shaping the future of ML pipelines and infrastructure as the platform scales.
The Ideal Candidate:
You’re a self-starter with a background in designing and developingevent-drivensystems using the JVM. You're interested indistributed systemsandreal-time performance. You have experience in designingevent-driven architectures, handling massive amounts of data, and scaling platforms to meet demanding client needs. Most importantly, you’re excited to take ownership of solutions and drive the platform’s evolution.
