We are small, technically deep, and working on a problem the largest security vendors in the world have left unsolved. Based in London. Hybrid. Hiring for craft.
If you want to ship work that ends up defending telecom subscriber data, payment flows, patient records, and public services — with engineering rigour as a baseline rather than a slogan — this is the right place.
Engineers own features from design through production.
We ship when it's right. Infrastructure standards apply.
Networking, security, distributed systems and data engineering in one room.
Engineers talk to operators and incident responders, not just product managers.
A first conversation with the hiring manager.
A technical deep-dive relevant to the discipline.
A short paid practical or system-design exercise.
A final round with the founding team.
We move quickly and give clear answers.
Core platform infrastructure, request processing pipeline, health-checking and routing.
Detection capability, threat modelling, and the research that powers Parrera's verification layer.
Deployment, observability, and the infrastructure that keeps Parrera running at scale.
The data architecture behind Parrera's analytics, metrics, and incident evidence surfaces.
Working directly with telecom operators, enterprise security teams and integration partners.
