Come do work that matters.

Software Engineer — Platform Foundations

We are hiring a Senior Software Engineer to build and evolve the foundational systems that power our products. This role focuses on backend platform engineering, authentication and authorization, developer infrastructure, and secure AI-assisted automation.

You will work on high-impact systems used across the organization: identity, access control, APIs, asynchronous workflows, shared services, and background agents that help internal teams investigate and resolve operational issues.

## What you'll do

- Design, build, and operate reliable backend services and shared platform capabilities.
- Lead technical design for APIs, distributed systems, data storage, workflow orchestration, and service integrations.
- Build secure authentication and authorization systems for users, partners, services, and API clients.
- Develop and maintain login flows including SSO, OAuth/OIDC, MFA, session management, token lifecycle, and role- or scope-based access control.
- Improve platform security through strong access controls, auditability, secrets management, tenant isolation, and secure service-to-service communication.
- Build background-agent systems that automate support and operational workflows while maintaining clear safety controls and human oversight.
- Develop integrations with collaboration, ticketing, source-control, and internal operational tools.
- Create safe AI-agent execution patterns, including isolated runtimes, scoped permissions, tool allowlists, approval workflows, and output-safety checks.
- Improve reliability and operability through monitoring, tracing, incident response, testing, and performance engineering.
- Partner with product, security, infrastructure, and support teams to turn complex requirements into scalable platform capabilities.
- Mentor engineers, contribute to technical standards, and lead design discussions across teams.
- Lead complex projects, make strong architectural decisions, and improve the systems around them.
- Set technical direction for broader areas, align teams around platform investments, and create leverage through mentorship, standards, and architecture.

Technical environment

Our work includes:

- Go, TypeScript, and Node.js
- RESTful APIs and distributed services
- PostgreSQL, MongoDB, and event-driven systems
- Workflow orchestration and asynchronous job processing
- Docker, Kubernetes, cloud infrastructure, and CI/CD
- OAuth 2.0, OIDC, SAML, JWTs, MFA, RBAC, API scopes, and service authentication
- Observability tooling, including metrics, logs, tracing, and alerting
- AI-agent frameworks, tool calling, secure execution environments, evaluations, and human-in-the-loop workflows

## What we're looking for

- 6+ years of professional software engineering experience.
- Strong backend engineering experience in Go, TypeScript/Node.js, Java, Python, or a similar language.
- Experience designing and operating production distributed systems, APIs, databases, and asynchronous workflows.
- Strong understanding of authentication, authorization, sessions, tokens, identity protocols, and secure API design.
- Experience building secure, reliable systems that handle sensitive data and enforce access controls.
- Familiarity with cloud infrastructure, containers, Kubernetes, CI/CD, and production observability.
- Strong system-design skills and the ability to make sound technical tradeoffs.
- Clear written and verbal communication skills, including the ability to influence across teams.
- A practical ownership mindset: comfortable debugging production issues and improving systems end to end.

## Nice to have

- Experience with AI agents, LLM tool use, automation platforms, or human-in-the-loop systems.
- Experience designing secure agent runtimes, sandboxing, permission models, or safety controls.
- Experience with enterprise identity integrations and SSO.
- Experience with workflow engines, event-driven architectures, or platform engineering.
- Experience in fintech, security, healthcare, or another regulated industry.
- Experience mentoring engineers or leading cross-team technical initiatives.

Compensation:

- Base Salary Range: $124,000 – $146,000 (This applies to full time hires. Final offer determined by multiple factors, including but not limited to function, level, geographic location, job related knowledge, skills, and experience.)
