Software Engineer, Early Career

Flow Engineering; San Francisco (CA); On-site; USD 120,000 - 170,000; Full time

Job summary

Flow Engineering is hiring early career software engineers to build AI-powered capabilities for requirements engineering in hardware-focused teams. You will collaborate with experienced engineers on agentic systems and domain engineer workflows, bringing AI into how teams reason about their systems.

You will ship code to production early, work directly with customers on rockets and satellites, and learn full-stack and AI engineering from seasoned mentors in a fast-moving environment.

Qualifications

• Less than two years of engineering experience.
• Solid fundamentals in data structures, algorithms, and distributed systems.
• Customer-minded, pragmatic approach to solving problems.
• Exposure to modern LLM tooling ( coursework, side project, or internship ).

Responsibilities

• Ship AI-powered features enabling assisted requirement drafting and intelligent suggestions.
• Contribute to agentic workflows for design exploration, simulation, and validation of requirements.
• Work across the stack from backend to UI to own complete features.
• Help build data pipelines, evaluation harnesses, prompt/model management, and observability.
• Talk to customers, observe actual usage, and iterate quickly.
• Learn domain knowledge of hardware-requirements engineering.

Job description

About Flow

Flow Engineering is an AI-native requirements platform for modern engineering organizations, enabling hardware teams to collaborate with AI agents to design, validate, and evolve complex systems with speed and rigor.

About the role

Note that this is NOT a new grad role! This role is for candidates with 0-2 YOE and can start full time right away.

Flow is hiring early career software engineers to help build AI-powered capabilities that let teams author, review, and manage requirements more effectively. You will work alongside experienced engineers on agentic systems engineer and agentic domain engineer workflows, bringing AI into the center of how teams reason about their systems.

This is a role for people early in their careers who are ready for an unusual amount of responsibility and autonomy. You will ship code to production in your first weeks, work directly with customers building rockets, satellites, and aircraft, and learn full-stack and AI engineering from people who have done it before.

What you'll do

• Ship AI-powered features such as assisted requirement drafting, consistency checks, impact analysis, and intelligent suggestions for systems and domain engineers.




• Contribute to agentic workflows that help engineers explore designs, simulate changes, and validate requirements.




• Work across the stack, from backend services and APIs to the UI, so you own complete features rather than isolated pieces.




• Help build the surrounding infrastructure: data pipelines, evaluation harnesses, prompt and model management, and observability.




• Talk to customers, watch how they actually use what you built, and iterate quickly.




• Learn the domain. Requirements engineering for hardware is deep, unfamiliar to most software engineers, and the reason our product is hard to copy.

About you

• You have less than two years of engineering experience. You have solid fundamentals in data structures, algorithms, and distributed systems, with a customer-minded, pragmatic approach to solving problems.




• Strong programming fundamentals and demonstrated ability to build real software, whether through internships, research, open source, or personal projects you can walk us through.




• Some exposure to modern LLM tooling, whether that is coursework, a side project, or an internship. You do not need production AI experience, but you should be genuinely interested in building with these systems.




• Clear communication. You can explain a technical decision and say when you are stuck.




• Comfortable with ambiguity and eager to work in a fast-moving environment where the roadmap changes and experiments are the norm.

Our stack (AI-leaning)

• TypeScript/Node.js and Python for AI and backend services.




• Modern LLM APIs and orchestration libraries for building agentic workflows.




• Postgres and other managed cloud services for data and state.
