Sr. Fullstack Platform Engineer - (Backend Focus)

Salt AI is building the governed execution platform for AI work that has to be real, deployable, and reliable enough for regulated industries. They are seeking a Senior Fullstack Platform Engineer who will focus on backend and platform work, ensuring a seamless customer experience across infrastructure, APIs, and UI surfaces.

Responsibilities:

• Workflow and agent execution. Build the contracts that let agents call real pipelines with typed inputs, structured outputs, streaming status, retries, logs, and auditability
• Python and Django platform services. Model platform concepts cleanly, build durable APIs, evolve service boundaries, and make customer workflows reliable at the backend layer
• Kubernetes-backed execution. Work on deployment patterns, scaling, isolation, runtime behavior, observability, and operational reliability for AI workflows
• Fullstack platform surfaces. Build the frontend and backend experiences customers use to configure, run, inspect, debug, and reuse AI workflows
• Permission-aware data access. Build secure customer data access patterns, retrieval systems, indexing, hybrid search, and APIs that respect enterprise boundaries
• Reliability and observability. Make distributed AI workflows understandable: what ran, what changed, what failed, why it failed, and what the user or system can do next
• Platform abstractions. Turn one-off customer implementations into reusable capabilities without sanding off the important domain-specific details
• Developer and operator experience. Improve the tools, docs, test harnesses, internal workflows, and diagnostics that let a small team move quickly without losing control of the system
