Why This Job is Featured on The SaaS Jobs
This role sits at the infrastructure layer of an AI-first SaaS product, where agent experiences depend on runtime guarantees rather than model prompts alone. Building the foundation for multi-turn orchestration, tool execution, and streaming responses is increasingly central across SaaS as assistants move from demos to production features with real uptime and trust expectations.
From a SaaS career standpoint, the work maps to problems that recur in modern platforms: multi-tenant reliability, latency and tail performance, cost control tied to usage, and operational rigor through observability and SLO thinking. The combination of distributed systems and ML infrastructure integration also reflects a growing intersection in SaaS engineering, where product capabilities are constrained by routing, state, and safety mechanisms as much as by application code.
The role is best suited to engineers who prefer end-to-end ownership of core services and are comfortable making tradeoffs across correctness, performance, and operability. It will appeal to those who like deep production work, structured debugging, and collaborating with product-facing teams to translate agent behavior into measurable platform guarantees.

Job Description
About the Role:
The Agents Runtime team builds the low‑latency, reliable, and secure foundation that powers Glean’s AI agents and assistant experiences at scale. You’ll design and operate core runtime services for multi‑turn orchestration, tool calling, model routing, memory, streaming, and safety. You’ll work across distributed systems, production observability, and ML infra integrations to deliver an experience that feels instant, accurate, and trustworthy — while optimizing cost and reliability.
You will:
- Own impactful runtime problems end‑to‑end — from architecture and design to production launch and ongoing reliability.
- Build and evolve core services for session lifecycle, streaming responses (e.g., gRPC/WebSockets), structured tool execution, memory/state, and policy/guardrails.
- Design for performance, correctness, and cost: reduce p50/p95 latency, improve tail behavior, and optimize token/tool budgets.
- Integrate with leading LLM providers (e.g., OpenAI, Anthropic, Google Gemini) and internal evaluation frameworks to improve quality and predictability.
- Harden the platform with fault isolation, retries, timeouts, circuit‑breaking, backpressure, and graceful degradation.
- Instrument deep observability (tracing, metrics, logs) and create playbooks/SLOs for high availability and on‑call excellence.
- Collaborate closely with product, quality, and application teams to prioritize the most impactful roadmap investments.
You are:
- 3+ years of software engineering experience building production distributed systems or cloud‑native applications.
- BS/BA in Computer Science or related field, or equivalent practical experience.
- Strong coding skills in at least one of: Python, Go, Java, or C++, with a focus on reliability, performance, and tests.
- Product‑minded: you prioritize customer impact, clear SLAs/SLOs, and pragmatic iteration.
- Ownership‑driven with a positive, proactive attitude; comfortable leading projects or learning from battle‑tested engineers.
- Experience operating services on Kubernetes and at least one major cloud (e.g., GCP, AWS, or Azure).
- Familiarity with event/streaming systems (e.g., Pub/Sub, Kafka), caching (e.g., Redis), and data stores for low‑latency paths.
- Practical understanding of LLM/agents building blocks: tool/function calling, structured outputs, streaming, and model selection/routing.
- Strong observability and debugging skills: tracing (e.g., OpenTelemetry), metrics, dashboards, and production forensics.
- Background in one or more areas is a plus: policy/guardrails, multi‑tenant isolation, rate‑limiting, concurrency control, cost optimization.
Location:
- This role is hybrid (3-4 days a week in one of our SF Bay Area offices)
