- AI evaluation and observability - You consider metrics that measure the efficiency and reliability of our AI platform.
- Technical Decisions - Make sound technical decisions, specifically related to systems design, reliability, observability, latency, cost, safety, security, and governance.
- Collaboration - You can work in a cross-functional team with AI engineers, full stack engineers, product managers and designers.

What Sets You Apart

- Minimum 5+ years of experience in a software engineering, platforms engineering, or machine learning engineering
- Proven expertise in OCI specifications alongside hands‑on background managing secure, isolated container runtimes
- Demonstrated hands‑on experience architectural design and deployment of distributed, event-driven applications in production environments (familiarity with LangChain, OpenAI SDK, or Google ADK preferred)

Our Core Technology Stack

We build modern, scalable software on a thoughtfully designed stack:

- Frontend: TypeScript and JavaScript across Ember (today), React, and React Native.
- Backend: .NET / C# (Web API, .NET Core) powering distributed services.
- AI Microservices: Python (FastAPI/Google ADK, FastMCP) powering our AI agents
- Data: Postgres, SQL Server with performance and integrity at scale.
- Cloud: Microsoft Azure, Vercel.
- Observability: Metrics, logging, alerting, and dashboards in Datadog — because we believe you can’t improve what you don’t measure.

Our architecture continues to evolve as we scale. We invest in event-driven systems, well-defined microservices, and containerized deployments to build resilient, decoupled, and high-performing software.

If you care about clean service boundaries, reliable systems, and shipping with confidence — you’ll feel right at home here.
