Our customers are hardware teams in aerospace, defense, automotive, and adjacent industries, and their engineering work lives across PLM, ALM, requirements, and issue-tracking systems. Getting Flow to work cleanly with that existing stack is often what turns a pilot into a full deployment. This role sits between engineering, product, and our customers. You will design and ship integrations, own their reliability once they are live, and work directly with customer engineering teams to understand how their data actually moves. ## What you'll do - Design, build, and maintain integrations connecting Flow to customer systems such as PLM and ALM platforms (Solidworks, AutoCAD), requirements tools (Jama, DOORS), issue trackers (Jira, Linear), and version control (GitHub, GitLab). - Build reliable data sync, including mapping, transformation, conflict handling, and keeping records consistent across systems. - Work directly with customer engineering and IT teams to scope integrations, understand their data models, and get deployments live. - Design and maintain the APIs and webhooks that let customers and partners build against Flow. - Own integrations in production, covering monitoring, error handling, and debugging sync issues across systems you do not control. - Partner with forward deployed engineers and product engineers to turn recurring customer needs into reusable integration patterns. ## About you - 5+ years developing production software, including designing and operating services at scale in a cloud environment. - Experience building and maintaining integrations against third-party APIs, ideally in a customer-facing or B2B setting. - Strong grasp of API design (REST, webhooks, and related patterns) and the realities of syncing data between systems. - Comfortable debugging problems that span multiple systems, including ones where you have limited visibility. - Able to work directly with customers and translate their technical setup into a clear integration plan. - Comfortable in a high-ownership environment where you scope, build, and support your own work. ## Nice to have - Familiarity with PLM, ALM, or systems engineering tooling - Exposure to defense, aerospace, or regulated hardware environments. ## Our stack - TypeScript/Node.js and Python for backend and integration services. - REST and webhook-based APIs, message queues, and standard cloud infrastructure. ## About Flow Engineering ## Company Overview - **One-liner**: Flow Engineering provides an agentic platform for systems engineering that enables hardware teams to manage requirements, design, and testing through a living system of record and AI agents. - **Entity Type**: Private (Series stage not explicitly stated; raised ~$40M total from Sequoia Capital and others) - **Headquarters**: San Francisco, California, United States - **Founded**: 2023 - **Founders**: Pari Singh (CEO) ## Core Business - **Primary industry**: Systems engineering software / hardware development tools - **Target customers**: B2B, Enterprise – hardware engineering teams in aerospace, automotive, robotics, defense, and energy (e.g., Rivian, Joby, Astranis, Radiant Nuclear) - **Mission or purpose statement**: “Help unlock the next generation of hardware” – rebuild systems engineering for the agentic era, enabling teams to design, build, test, and iterate physical systems in hours, not months. ## Products & Services - **Flow Platform**: A requirements management and systems engineering tool that links requirements, design (CAD), simulations, code, and tests in a single “living system of record”. Features include branching/merging, impact analysis agents, systems graph, flexible data model, and AI agents (e.g., Impact Analysis Agent, Safety & Regulatory Compliance Agent, Mass/Cost/Power Budget Agent). Deployable in cloud, GovCloud, or self-hosted with ITAR, export control, and data residency. - **Flow v3**: Latest version – first agentic platform for systems engineering, allowing AI agents to perform real engineering work inside hardware development workflows. - **Flow Engineering Handbook**: Published guide on AI Systems Engineering for the agentic era. ## Market Standing - **Valuation/Market Cap**: Not disclosed - **Key Metric**: Total Funding ~$40M as of most recent round (non‑equity assistance and multiple seed rounds; led by Sequoia Capital and EQT Ventures); Annual Revenue estimated at $2.0M (LinkedIn data) - **Notable Investors/Partners**: Sequoia Capital (lead investor; partner Roelof Botha on board), Patrick and John Collison (Stripe co‑founders), David Helgason (Unity co‑founder), EQT Ventures, Google for Startups - **Growth Signals**: - Used by tens of thousands of engineers across teams like Rivian (1,500+ engineers), Joby Aviation, Astranis, Radiant Nuclear, Impulse Space, Mytra, Volkswagen Group Technologies. - Active job postings: 10–12 open roles (as of mid‑2026), with quarterly job posting growth of +66.7%. - Backed by Sequoia Capital (partnered in 2025); company has grown to ~27 employees with presence in US, UK, Sweden, Spain. - Headcount growth recent month showed -6.9%, but same‑source LinkedIn shows heavily active hiring pipeline. ## Competitive Advantages - **Agent‑first systems engineering**: First platform to integrate AI agents that reason across the entire engineering graph (requirements, CAD, simulation, test). Agents perform impact analysis, compliance checks, and budget tracking automatically. - **Defense‑grade security & compliance**: ITAR/EAR aligned, NIST 800‑171, CUI, SOC 2 Type II, ISO 27001, GDPR, CCPA – essential for regulated industries. - **Living system of record**: All engineering artifacts linked and version‑controlled with branching/merging, enabling zero‑cost change propagation. - **High‑value customer base**: Signed marquee hardware companies (Rivian, Joby, Astranis) that are building the next generation of rockets, eVTOL, satellites, and robots. - **Strong investor backing**: Sequoia Capital (a top‑tier VC) and technical co‑founder endorsements (Collison, Helgason) provide credibility and network. ## Strategic Focus - **Agentic transformation**: Doubling down on AI agents that can perform real engineering work (not just assist) – moving from analog/digital to “agentic” era. - **Scaling to enterprise & defense**: Expanding GovCloud, self‑hosted, and ITAR‑compliant deployments to win defense and compliance‑driven contracts. - **Category creation**: Replacing traditional requirements tools (like IBM DOORS) with a modern, agent‑centric platform. - **Global hiring**: Aggressively hiring for engineering (AI, frontend, full‑stack, infrastructure) and sales roles across San Francisco and London. ## Why Work Here - **Impact at scale**: Work directly on tools used by companies building rockets, electric vehicles, autonomous robots – your code ships into real hardware. - **Engineering culture**: Emphasis on shipping a V1 quickly, iterating, and maintaining “zero cost of change.” Values include speed, fundamentals done well, maximum effort/maximum fun. - **Work environment**: Hybrid/remote policies not explicitly stated, but roles are listed in San Francisco (in‑office likely for engineering) and London. Equity offered across all roles. - **Compensation**: Salaries range $120K–$300K for US roles with equity; London roles £80K–£180K. - **Team culture**: Backed by Sequoia, described as a “small team with huge leverage” – ~27 employees currently but growing fast. - **Notable perks**: Free trial demo available; engineering handbook published; company rating 4.0/5 on LinkedIn (16 reviews), with strong compensation (4.0) and culture (3.8) scores. ## Sources 1.
