WRITER is seeking a Software Security Engineer (Embedded) to design, build, and scale the systems that protect their users, their data, and their interactions with AI/AGI services. The role aims to blend deep software engineering expertise with a product mindset to deliver security tools, frameworks, and controls that serve millions of users without slowing them down, focusing on fraud prevention, abuse detection, identity systems, and secure-by-default development platforms.
Requirements
- 8+ years in software engineering, building production systems.
- 5+ years developing security-focused tools, libraries, or platforms.
- Proven success building systems adopted by hundreds of engineers.
- Experience with fraud detection or abuse prevention at scale.
- Deep expertise in distributed systems and API design.
- Strong programming skills in Go, Python, or similar languages.
- Expert in software design patterns and scalable architectures.
Responsibilities
- Protect customers at scale — Build fraud detection, rate limiting, abuse prevention, and LLM interaction controls (prompt injection prevention, output filtering).
- Own customer identity security — Design and implement authentication and authorization systems, protecting customer data and AI service interactions.
- Engineer security platforms — Create tools and dashboards that automate repetitive security tasks, track vulnerabilities, and enable cross-team security efficiency.
- Build reusable security frameworks — Develop secure-by-default APIs, SDKs, cryptographic libraries, and communication frameworks for company-wide use.
- Strengthen platform security — Implement multi-party authorization, secrets management, audit logging, and zero-trust networking components.
- Empower developers — Deliver self-service security tools and frameworks that integrate seamlessly with engineering workflows.
- Lead technically — Drive the architecture of security systems, mentor engineers, review designs, and influence security strategy across the organization.
