About the Product:
You’ll work on a cloud-native cybersecurity analytics platform used by Fortune-500 companies and global enterprises to understand and strengthen their security posture. It processes massive datasets, models attack paths, and uses AI-driven, graph-based analytics to surface the risks that truly matter.
The product is scaling fast, expanding to the SMB market across 32 European countries, and backed by a $100M+ growth investment round.

About the Role:

We’re forming a new engineering team and looking for a Senior Python Engineer.
You’ll be part of a group of senior engineers, driving architecture decisions, and staying deeply involved in debugging and performance optimization. You’ll participate in the design and development of new features end-to-end, working on a system built for scale, accuracy, and real-world security impact.
The role requires close collaboration with product and engineering teams to translate complex technical challenges into clean, reliable solutions.

Why This Role Stands Out:

• High-impact product used by major enterprises, built on real attack modeling and risk quantification
• Deep technical challenges – large-scale pipelines, distributed computation, graph modeling, real-time correlation
• Modern tech stack – Python, AWS, microservices, PostgreSQL, Redis, Docker, Kubernetes
• Become part of a high-bar team: 3 Senior Python + 1 Senior Angular engineers
• Backed by $100M+ investment and expanding across Europe
• Remote-first with strong support and competitive compensation

Required Competence and Skills:

• 5+ years of experience in software engineering
• Extensive experience in Python
• Experience with AWS
• Practical user-level experience working with Dockerized services and Kubernetes-based environments.
• Experience with PostgreSQL/MySQL, including modeling and performance tuning
• Experience working with Agile environments
• Excellent English and communication skills

Nice to have: 

• Big Data experience – big advantage

Why Us?

• We provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in).
• We provide full accounting and legal support in all countries we operate.
• We utilize a fully remote work model with a powerful workstation and co-working space in case you need it.
• We offer a highly competitive package with yearly performance and compensation reviews.

We are seeking a Senior Backend Engineer (Go+Java) to drive the evolution of the authorization platform. In this role, you will own the design and implementation of critical backend components, working with existing microservices written in Go and Java to deliver new functionality, migrate legacy code, and optimize performance. You will collaborate closely with product managers, frontend engineers, QA, and R&D teams to translate customer requirements into production-ready, scalable solutions. Given the platform’s complexity, high release cadence, and cloud-native foundation, you are expected to onboard quickly, work autonomously, and leverage AI-assisted development tools to increase delivery speed and quality. Your work will directly impact platform scalability, security posture, and customer satisfaction.

About the Product

Our product is a modern authorization platform that centralizes policy management and enforces dynamic, real-time access control across applications, APIs, and data. It combines centralized policy definitions with decentralized enforcement points to deliver low-latency authorization at scale. The platform integrates with leading IAM providers such as SailPoint, Okta, and Azure AD, and supports PostgreSQL, Elasticsearch, and MongoDB as backend data stores. Serving 100+ enterprise customers across finance, healthcare, and other regulated industries, the system processes millions of authorization requests per day, solving the industry challenge of fragmented and static access control. Reliability, security, and performance are critical in this high-volume, data-intensive, multi-tenant environment.
