We are looking for a Staff Engineer to steer the technical evolution of our AI‑centric business platforms, which currently prioritize ad revenue operations such as cross‑system intelligence, workflow automation, and document understanding. While the domain already supports live production traffic and active users, significant architectural challenges remain: how can non‑deterministic AI be effectively integrated into workflows where business outcomes depend on high accuracy? In this role, you will confront this ambiguity head‑on—defining architectural patterns, implementing them in production, and validating their effectiveness.

Tubi’s Internal Tools team is at the forefront of AI integration, developing everything from developer resources to production‑grade AI for business operations. We are the group responsible for turning AI from an experiment into an operating capability: training, infrastructure, developer agents, and AI‑powered business systems. Engineers operate with high ownership and autonomy, collaborating on shared architectural decisions and AI infrastructure.

Define and drive the technical architecture of the AI platform—spanning extraction pipelines, confidence scoring, cross‑system data aggregation, and user‑facing intelligence layers. Own the platform’s most complex subsystems and hardest design problems: reliability under non‑determinism, integration across heterogeneous data sources, and progressive automation with appropriate human‑in‑loop gates.

Ship consistently. Turn ambiguous requirements into working software that users see and trust. Mature the platform’s AI systems from early‑stage to production‑grade: systematic validation, feedback loops that improve accuracy over time, and principled cost management.

Provide clear technical analysis when leadership needs to understand trade‑offs, feasibility, or risk.





8+ years of software engineering experience, with demonstrated ability to own and deliver complex systems end‑to‑end—from design through production operation.

Deep expertise in distributed systems design, fault tolerance, and building reliable systems from unreliable components.

Strong full‑stack engineering fundamentals.

Our stack: Node.js/TypeScript (backend, Express), React/TypeScript (frontend), PostgreSQL with Drizzle ORM, Python for ML pipeline components, OpenAI and Google Gemini APIs.

Demonstrated bias toward shipping. Good technical judgment under uncertainty.

Experience designing systems that handle non‑deterministic or probabilistic outputs (ML models, LLM pipelines, or similar) with appropriate confidence scoring and fallback strategies.

Familiarity with LLM application patterns: prompt engineering, multi‑model orchestration, agentic tool use, and cost optimization for high‑volume LLM workloads.

Experience with document AI or structured data extraction from unstructured sources (documents, image, natural language) at scale.

Experience building over heterogeneous enterprise data sources with varying freshness, schemas, and access patterns.

The AI Mandate Building systems where human operators can progressively delegate to AI—and where the blast radius is contained when AI is wrong.

AI as Leverage: Thinking about AI as a force multiplier for a small team.

Cost Discipline: Treating AI spend as an engineering problem—optimizing for accuracy per dollar,



not just accuracy alone.
