Job Description

About the role

We're looking for a hands-on senior engineer and architect to turn our agentic AI work into secure, scalable products inside the TrustX platform. You'll set the technical direction and also write the code. You'll work across architecture, AWS, identity, security and APIs, and take prototypes all the way to production.

You'll help evolve our Agent Gateway and Model Context Protocol (MCP) capabilities, and strengthen how AI agents, users and enterprise services connect to each other securely.

We're keeping the team small. You'll use AI-assisted tools such as GitHub Copilot throughout your work so a few people can do the work of many. This is mainly an individual contributor role, with the chance to lead a small team as the product grows.

NOTE: This is a hybrid role requiring on-site presence in our Fairfax, VA office, it is not a 100% remote role.

What you'll do

• Design and build agentic AI capabilities for TrustX.
• Evolve the Agent Gateway and MCP architecture and the services around it.
• Design how AI agents, users, applications and outside services connect securely, including authentication, authorization, delegation and trust for both people and non-human identities (OAuth 2.0, OIDC, JWTs, SPIFFE/SPIRE, workload identity).
• Build cloud-native services and APIs, mainly on AWS.
• Evaluate new agent protocols, identity standards and AI technologies, and decide what belongs in the product.
• Prototype quickly, then turn what works into production-quality code.
• Make practical architecture decisions that balance security, scalability, maintainability and speed. Set the patterns and reference architectures other engineers follow.
• Work with product, engineering, research, security and operations. Mentor, and lead a small team as the product grows.

Required

• 8+ years building and shipping commercial software, including production SaaS.
• Strong software engineering and system design skills.
• Hands-on AWS experience designing and running production services.
• Deep knowledge of OAuth 2.0, OpenID Connect, tokens and API security.
• Experience designing REST APIs and distributed services, and securely integrating separately operated systems.
• Solid grasp of containers and modern cloud deployment.
• Experience taking software from prototype to production.
• Experience building with LLMs or agent frameworks.
• Able to learn unfamiliar technology on your own and solve unclear problems.
• Clear communication with engineering and product teams about architecture decisions.

Preferred

• Experience with MCP, SPIFFE/SPIRE or workload identity.
• Background in identity, biometrics or authentication products.
• Experience leading or mentoring engineers.
• Daily use of AI-assisted development tools.
