Job summary

Flow Engineering, Inc. is seeking senior software engineers to build AI-powered capabilities that help teams author, review, and manage requirements with speed and rigor. You will create agentic workflows integrating AI into the design and validation process for complex systems.

You will own end-to-end features from prototype to production, working across backend, APIs, and lightweight UI hooks. A strong track record with cloud services and large language models is essential.

Qualifications

• 5+ years developing production software, including designing, testing, and operating services at scale in a cloud environment.
• Hands-on experience with modern LLM providers and tooling (e.g., OpenAI, Anthropic, Hugging Face, vector stores, RAG patterns).
• Familiarity with prompt design, retrieval-augmented systems, evaluation methods, and safety/guardrail approaches.
• Ability to reason about tradeoffs between different models, architectures, and deployment patterns and make pragmatic decisions.
• Comfortable working in a high-ownership, fast-paced environment where experiments and iteration are the norm.

Responsibilities

• Design and ship AI-powered features such as assisted requirement drafting, consistency checks, impact analysis, and intelligent suggestions for systems and domain engineers.
• Build agentic workflows that help "agentic systems engineers" and "agentic domain engineers" explore designs, simulate changes, and validate requirements.
• Evaluate and integrate language models and related tooling, optimizing for reliability, latency, cost, and debuggability in production.
• Build and maintain the surrounding infrastructure: data pipelines, evaluation harnesses, prompt and model management, observability, and safety/guardrails.
• Work across the stack-from backend integrations and APIs to simple UI hooks, to deliver complete AI features, not just model endpoints.
• Partner with product and customers to identify high-value workflows, run experiments, and iterate quickly based on usage.
