Founding Software Architect

Nov 30, 2025

About us

We are an early-stage, venture-backed cybersecurity AI startup currently operating in stealth mode. Founded by two former public company senior executives with deep expertise in Identity, Data security, ITSM, and enterprise security, we’re building innovative solutions at the intersection of cybersecurity and AI. Our mission is to redefine how enterprises securely adopt and deploy cutting-edge AI applications, ensuring compliance, trust, and safety in a rapidly evolving digital landscape. With agility at our core, we move swiftly, scale efficiently, and adapt rapidly to tackle complex security challenges. If you’re passionate about cybersecurity, AI, and want to shape the future of secure enterprise technology, join our visionary team. We are now looking for a founding Software Architect to help lay the technical foundation for highly scalable, secure, and reliable systems that defend the future of AI security.

About the role 

As our founding Software Architect, you’ll lead the design and development of our core systems from the ground up, partnering closely with our Chief Technology Officer. You’ll architect scalable, high-throughput distributed and agentic systems with strong identity and access controls, working closely with developers and product leaders to bring new AI security primitives to life. This role offers deep ownership over product architecture and the opportunity to shape a company at the frontier of AI and security. You’ll be instrumental in defining our product direction and driving technical innovation at the intersection of identity and access management, cybersecurity and AI.

Responsibilities 

  • Partner closely with the CTO to design, architect, and implement scalable enterprise

  • software systems from scratch.

  • Design and architect distributed systems optimized for scale, performance, and high

  • availability

  • Build security-critical infrastructure that powers our AI security platform, including APIs, data pipelines, and policy enforcement layers

  • Implement Identity and Access Management primitives (authentication, authorization, least privilege) for AI-native environments

  • Ensure robust encryption, key management, and secure access controls throughout the system

  • Collaborate with developers and product managers to translate abstract security problems into scalable solutions

  • Drive technical decisions across system architecture, language/framework selection, and deployment models (e.g. serverless, containerized, etc.)

  • Develop observability, fault tolerance, and auditability into everything you build

  • Stay hands-on with code, especially in early stages — this is a build-first, zero-bureaucracy role

Required skills 

  • Experience developing software leveraging AI tools (coding assistants, IDEs, etc.)

  • 10+ years of backend or systems engineering experience, with 3+ years in an

  • architecture or principal engineer role

  • Deep experience designing and building scalable distributed systems (microservices, event-driven architectures,agentic architectures, etc.)

  • Proven track record of high-throughput, low-latency backend development in cloud-native environments

  • Expertise in IAM systems, protocols (OAuth2, SAML, OpenID Connect, SCIM), and access control patterns

  • Strong coding skills in one or more backend languages (Go, Rust, Java, Python)

  • Familiarity with modern DevSecOps practices, infrastructure-as-code, CI/CD, and cloud platforms (AWS, GCP, Azure)

  • Strong systems thinking and an ability to balance speed, security, and maintainability

  • Understanding of agentic AI and LLM-based application architectures

  • Preferred skills

  • Familiarity with zero-trust architecture, policy-as-code (OPA/Rego), and secure enclaves

  • Experience as an early-stage technical leader or founding engineer 

Why join us 

  • Built at the frontier of AI-native security and agentic infrastructure

  • Take true ownership of the systems you build, from design to production

  • Help define the product, engineering culture, and architecture of an ambitious early-stage startup

  • Work with a focused, high-caliber team that values speed, creativity, and autonomy
