Avalanche is a Seattle-based start-up developing compact fusion machines for clean, energy-dense power generation at a scale you can hold in your hands. Our unique approach allows us to build, test, break, learn and iterate in days. The modular design is designed to provide power to applications from austere environments to deep sea vehicles and maritime transport to lunar power.

We know we have an incredibly ambitious mission, and that it requires a wide combination of skills, attitude, and grit to make it happen. If you have a passion for abundant energy, and how we can improve life with it, we want to have a chat with you.

Avalanche might be fit for you if: You are self-motivated, energized by problem solving and working closely with hardware. You enjoy hands-on, creative collaboration with a small, tight-knit team you can work with, laugh with, and learn with on a wide variety of topics. You can learn and pivot between priorities when necessary and you can slide the headphones on, focus, and auger deep into a single topic as needed. You thrive in an atmosphere of development, and you are an ardent learner who’s always looking for ways to grow and improve.

We are seeking a Capture & Proposal Lead to build the pursuit strategies, communications, and operating discipline required to convert qualified opportunities into funded government and commercial programs. This role owns the capture and proposal process from opportunity qualification and pursuit planning through white papers, proposals, negotiation support, award, and transition to program execution, with particular emphasis on technically complex R&D, prototype, demonstration, production, and strategic partnership opportunities.

You will report to the Director of Strategy and work closely with business development, government relations, science & engineering, finance, legal/contracts, compliance, and program management to develop differentiated win strategies, shape customer engagements, lead cross-functional proposal teams, and produce compelling, compliant, and technically credible submissions and strategic communications. You will also strengthen the systems behind growth by managing capture and proposal workflows, CRM and pipeline governance, reusable content, IP and data-rights coordination, and the formal handoff of awards to program teams. The role requires both a hands-on writer and operator and a process owner who can make Avalanche's pursuit organization increasingly rigorous, repeatable, and scalable as the company grows.
