Senior Backend Engineer (f/m/x) in Cybersecurity Start-up (minimum 3 years experience)

🏢 Company: CyberDesk

🌱 Type: Full-time | Early-stage team | Equity available

🧠 About CyberDesk

AI agents, ephemeral cloud services, and machine-to-machine interactions are breaking traditional access control models. At CyberDesk, we’re building an intelligent platform to dynamically manage access — across humans, systems, and APIs — with risk-aware, policy-driven decisions.

We combine identity metadata, access graphs, and real-time risk scoring to enforce least-privilege access at scale. Our backend stack is designed to evaluate and authorize actions in milliseconds, integrating with identity providers, cloud services, and enterprise environments — all while remaining compliant with NIS2, DORA, and GDPR.

🔍 The Opportunity

We’re looking for a Senior Backend Engineer to architect and scale our access decision engine, integrate external identity providers, and build our authorization graph infrastructure. This is a deeply technical role at the heart of our platform.

🛠️ Your Responsibilities

• Build and maintain a scalable, testable, and extensible backend using TypeScript and Bun.js in a modern, modular codebase.

• Design and implement integrations with third-party SaaS APIs (e.g., Google Drive, Microsoft 365, SharePoint) to support federated data access and identity mapping.

• Develop cloud-native infrastructure and backend components using AWS services: Lambda, SQS, S3, DynamoDB, OpenSearch, Secrets Manager.

• Collaborate with product and security teams to evolve serverless and event-driven architecture for real-time access control decisions.

• Support the secure processing of regulated data, including NHI (National Health Identifiers) and PHI (Protected Health Information), with strong focus on data protection and compliance.

✅ What You Bring

• 3–5 years of backend development experience, with a strong foundation in TypeScript and familiarity with Bun.js or Node.js runtime environments.

• Experience building secure, cloud-native applications and API-driven systems at scale.

• Solid grasp of authentication flows and identity protocols (OAuth2, OpenID Connect, SAML).

• Comfortable with infrastructure-as-code, event-based systems, and REST/gRPC API design.

• Open-mindedness to work with Python when needed — e.g., for AI/ML model integration.

💡 Nice to Have

• Experience working with Azure or Google Cloud Platform (GCP) in addition to AWS.

• Prior experience handling regulated data types (e.g., NHI, PHI, PII) and meeting compliance standards (e.g., HIPAA, GDPR).

• Python experience (scripts, services, or integrations) alongside your TypeScript expertise.

• Familiarity with policy engines or graph-based access control systems.

• First experience contributing to AI-enabled cybersecurity products, such as anomaly detection or behavior-based access logic.

✨ Why CyberDesk?

• Foundational role: Build the authorization backend that powers dynamic access for humans and machines.
• Deep tech: Join a team that obsesses over low-latency policy evaluation and scalable security architectures.
• Flexible setup: Remote-first culture, async collaboration, strong documentation.
• Equity & growth: Be an early team member in a fast-scaling company backed by EU cyber initiatives.

🎁 Benefits

• Early-stage equity — meaningful ownership in a fast-growing deeptech startup.
• Annual team retreat — in-person strategy & bonding time in inspiring locations - this year we will meet in Georgia!
• Founders-level visibility — direct access to decision-making and strategic discussions.
• Tech gear — budget to set up your ideal remote workspace.
• One moving day per year — take the day off to relocate, stress-free and uninterrupted.
• Learning & development budget — for conferences, certifications, or online courses (e.g., AI, cybersecurity, product leadership).
• Health or transport stipend — monthly allowance for your fitness or public transport.

🚀 Our Hiring Process (Fast, Friendly & Founder-Led)

• You Apply: Send us your resume, portfolio, or anything you think we should see. We (founders & team) review it directly — not an algorithm.
