We build and operate full-size autonomous cargo aircraft - capable of carrying two tons of payload over a thousand nautical miles. From remote communities to contested logistics operations, our platforms unlock a new cost curve for air freight, making it faster, cheaper, and accessible anywhere it's needed. Headquartered in the San Francisco Bay Area with locations in Washington DC, Oregon, and Maine; we're building something consequential. This program is full-time and in person based in San Francisco The Maine Composites Bridge program invests in Maine's industrial future by providing local composite technicians an opportunity to participate in advanced aerospace manufacturing at Poseidon's headquarters in San Francisco. Drawing on Maine's rich heritage in naval manufacturing, participants gain hands-on experience with cutting-edge aerospace applications before returning to apply these specialized skills in Maine's manufacturing ecosystem with Poseidon. About the Job: As a composite technician at Poseidon Aerospace you will be responsible for the fabrication and assembly of advanced composite components for aerospace prototype and development programs. This role requires a strong understanding of composite materials, custom tooling, and hands-on manufacturing techniques. The ideal candidate is a skilled fabricator who can interpret engineering concepts, build tooling or jigs as needed, and support one-off as well as high-rate composite builds from start to finish. Responsibilities: - Fabricate composite components using hand layup, resin infusion, and bonding techniques. - Build, modify, and maintain custom molds, fixtures, and jigs to support prototype part fabrication and assembly. - Collaborate closely with engineers and designers to interpret 3D models, drawings, and verbal instructions. - Develop and refine layup methods, cure cycles, and fabrication approaches for new designs. - Set up and monitor vacuum bagging, and oven curing processes. - Trim, drill, and assemble complex composite parts to tight tolerances using manual and power tools. - Perform surface preparation, adhesive bonding, and final finishing operations. - Maintain traceability of materials and processes to meet aerospace documentation requirements. - Identify and communicate design or manufacturability issues and propose practical solutions. - Contribute to continuous improvement initiatives in prototype and production transition efforts. Ideal Qualifications: - 3+ years of hands-on composite fabrication experience (prototype, marine, or aerospace environment preferred). - Proficiency with hand layup, prepreg handling, and vacuum bagging techniques. - Ability to read and interpret engineering drawings, CAD models, and process specifications. - Strong problem-solving and troubleshooting skills in a fast-paced, dynamic environment. - Comfortable working with epoxy resins, adhesives, and solvents while following safety procedures. Nice to Have: - Experience fabricating or modifying jigs, fixtures, or tooling using metal, wood, or composite materials. - Familiarity with precision measurement tools and quality inspection processes. - Familiarity with 3D modeling software. - Experience working in a fast paced prototyping environment and large scale production. ## WHAT YOU GET FROM US - Competitive salary and meaningful early-stage equity - Relocation support if applicable - Employee Health Benefit Plans - 6% Retirement matching - Flexible PTO - Free lunches, snacks, and a stocked fridge at our offices - AI tools and subscriptions ## About Poseidon Aerospace ## Company Overview - **One-liner**: Poseidon Aerospace is reimagining logistics with autonomous aircraft built to move goods faster, cheaper, and anywhere they are needed, fundamentally changing the cost curve for air freight. - **Entity Type**: Private (Startup) - **Headquarters**: San Francisco, California, United States - **Founded**: Not publicly available - **Founders**: David Zagaynov (CEO) ## Core Business - **Primary industry**: Aerospace, Aviation, and Defense Logistics - **Target customers**: Government/Defense (military logistics), Commercial logistics providers, and Enterprise supply chains - **Mission**: To make air logistics as affordable and flexible as possible by driving the cost per ton-mile down to levels never before achieved in aviation, building the unmanned backbone of tomorrow's logistics. ## Products & Services - **Seagull (Unmanned Cargo Aircraft)**: An autonomous, unmanned cargo drone designed to lift two tons. The aircraft is a seaplane, requiring no airports or runways—only water—to operate. This unlocks millions of miles of navigable waterways for logistics. The platform is built from the ground up as a clean-sheet design, leveraging composites and advanced manufacturing. ## Market Standing - **Valuation/Market Cap**: Not publicly available - **Total Funding**: $12.4 million USD - **Funding Rounds**: - Pre-Seed: Led by Starship Ventures (1 investor) - Seed (2025-01-01): $1.4M from 2 investors - Seed (2025-11-01): $11.0M from 7 investors, led by Tamarack Global - **Notable Investors/Partners**: Tamarack Global (Lead), Starship Ventures, Sean Hoge (Lead Investor) - **Growth Signals**: Headcount grew +366.7% year-over-year to 20 employees; actively hiring for high-impact roles; secured a partnership with Northeastern’s Roux Institute and their National Security Innovation Hub to expand presence in Maine; FY2026 NDAA includes a provision for a pilot program for contracted amphibious aircraft, validating the market. ## Competitive Advantages - **Seaplane Design**: The aircraft requires no airports or runways, only water, unlocking millions of miles of navigable waterways and making logistics possible in remote, contested, or infrastructure-poor regions. - **Cost Curve Disruption**: By driving down the cost per flight-ton-mile, Poseidon aims to make air cargo as affordable as ground or maritime transport, a fundamental shift in logistics economics. - **Defense & Government Focus**: The company is strategically aligned with U.S. national security priorities, specifically "contested logistics" as highlighted by the Department of Defense, giving it a clear and funded customer base. - **Speed & Agility**: As a small, focused team (20 employees), the company claims to move with immense speed, building clean-sheet autonomous planes from scratch using advanced composites and manufacturing techniques. ## Strategic Focus - **Scaling the Team**: Actively hiring across engineering, operations, and government relations to support rapid growth (headcount up +366.7% YoY). - **Government & Defense Contracts**: Winning contracts is a core focus, with a dedicated Proposal Lead role and a Director of Government Relations position. The company is positioning itself to be a key player in the U.S. military's "contested logistics" strategy. - **Expanding Manufacturing & Presence**: Partnering with Northeastern’s Roux Institute in Maine to build a presence in a region with a deep aerospace heritage and access to a national security innovation hub. - **Product Development**: Building and iterating on the "Seagull" unmanned cargo aircraft, with a focus on composites and clean-sheet design. ## Why Work Here - **High-Impact, Early-Stage Environment**: The company has grown from 4 to 20 people in a short period, offering the chance to build foundational systems and processes from the ground up. - **Cutting-Edge Technology**: Work on clean-sheet autonomous aircraft, advanced composites, and manufacturing engineering in a fast-paced, iterative environment. - **Mission-Driven**: The work directly impacts national security and global logistics, with a clear, compelling mission to make air cargo as affordable as ground transport. - **Culture & Perks**: On-site work in San Francisco, CA. The company emphasizes a "punch above its weight" culture with a focus on engineering excellence and speed. Active hiring for high-impact roles across engineering, operations, and government relations. - **Recent Growth**: The team has grown from 4 to 20 people in a short period, offering significant ownership and career growth opportunities for early employees. ## Sources 1.
