Senior Software Engineer, Full-Stack

Orbis is hiring a Senior Software Engineer, Full-Stack to own product surfaces across its AI portfolio, from data models and services to user interfaces. The role focuses on real-time agent output, explainable results, evolving knowledge structures, reliable service contracts, and engineering quality, while mentoring junior engineers and leading design review and planning.

Responsibilities:

• Design and ship features end to end — data model, service logic, API surface, and the user-facing interface that consumes them
• Build and own the real-time surfaces of the products: streaming agent output, live task status, and progressive rendering of long-running analysis
• Make results explainable in the product by surfacing source, provenance, and reasoning path, so a user can judge a conclusion instead of trusting it
• Build interfaces over dynamic ontologies and knowledge structures that stay navigable as the underlying representation evolves
• Guarantee the service contracts you expose — versioning, backward compatibility, and failure semantics that consuming teams can rely on
• Set quality standards for the surfaces you own, including test coverage, accessibility, and front-end performance budgets
• Mentor junior engineers and lead design review and planning for the subsystems you own
• Travel up to 15% for customer engagement, integration support, and team collaboration

Requirements:

• 4+ years of professional full-stack engineering experience with demonstrated ownership of production product surfaces
• Bachelor's degree in Computer Science, a related technical field, or equivalent professional experience
• Strong TypeScript/JavaScript across server and browser runtimes, or a strong Python back end paired with real front-end skill
• Production experience with a modern front-end framework (React preferred), including component architecture, state management, and rendering performance
• Working knowledge of API design, including versioning, error contracts, authentication, and authorization
• Hands-on experience with real-time client-server patterns such as WebSockets, server-sent events, or streaming HTTP
• Experience presenting complex, interrelated data such as entities, relationships, graphs, timelines, or cited documents
• Familiarity with LLM application patterns, including streaming responses, retrieval, tool calling, and structured output
• Experience with graph databases or knowledge representation, and querying them at interactive latency
• Experience building SDKs or developer-facing libraries where other engineers are the customer
• Experience packaging and deploying to on-premises, disconnected, or edge environments (Docker, Kubernetes, offline installation)
• Familiarity with accessibility standards (Section 508 / WCAG) in a government or enterprise context
• Prior experience in a mission, government, or regulated environment where operational reliability is foundational
