About Intessera
Intessera delivers expert work through software. Our PXs (Professional Extensions) are software-based experts that analyze problems, apply judgment, and complete work within agreed limits. Customers retain approval authority. Our Outcome as a Service model ties delivery to agreed acceptance criteria.
Our work spans manufacturing and engineering through Intent to Actual, and training and wargaming through Red Teams. Customer-specific process knowledge, decisions, and work stay with that customer. We reuse the platform and delivery methods, not proprietary customer knowledge.
The role
Build and maintain the shared software behind PX delivery. Work directly with co-founder Andrew Kucheriavy on backend services, model integration, and reliable workflows. Your focus is the product, not a separate custom build for every customer.
What you will do
• Build services that let PXs use approved records and tools, perform assigned work, and record the basis for decisions.
• Own model integration, workflow configuration, versioning, and failure handling.
• Add task permissions, approval steps, and escalation paths that match each customer's agreed limits.
• Keep customer data and process knowledge isolated while making the underlying software reusable.
• Build automated tests and monitoring; improve reliability, response time, and operating cost.
• Turn repeated deployment work into configurable features, working with customer-facing engineers.
• Review changes, document important decisions, and troubleshoot production issues.
What you bring
• Experience designing, shipping, and operating backend software in production.
• Hands-on experience integrating language models with data, tools, and application workflows.
• Strong engineering fundamentals in APIs, databases, testing, access control, and debugging.
• Ability to distinguish a reusable product feature from customer-specific configuration.
• Clear written communication and the ability to own technical decisions in a small team.
Our current backend uses Python, FastAPI, and Postgres. Experience with customer-controlled deployments or manufacturing data is useful.
U.S. citizenship required. Customer assignments are subject to applicable export-control and data-handling requirements.
