Sr. Startup Solutions Architect, Early Stage Startups

Come work with the founders building whats next.

Some of the most important companies of the next decade are being built right now in Southern California by two or three people and an idea. Were looking for someone who wants a front-row seat to all of them and the technical chops to help make them real.

Youll work across AI/ML FinTech ClimateTech healthcare consumer B2B SaaS and whatever gets invented next with many of these companies coming straight out of Y Combinator and other top accelerators or freshly backed by leading VC firms. They need a trusted technical voice in their corner from day one and you get to be it. Picture a small team with a technical founder and maybe a couple of engineers moving fast with Claude Code Codex and whatever tool shipped last week trying to make every product architecture and business decision at once. Theres no VP of Engineering to align with no platform team to hand things off to and no multi-quarter roadmap so for the startups you work with you become the closest thing they have to a fractional CTO or chief architect. Thats what makes this an adventure rather than a support role: you and the founders are figuring it out together and a single good decision can save six months of runway while a bad one can quietly sink the whole thing.

The work is bigger than architecture and it changes week to week. One week youre helping a team understand the architecture their coding agent quietly built for them and untangling the decisions they didnt realize theyd made the next youre figuring out how to scale after an unexpected viral launch and the week after that youre working a compliance problem with a FinTech startup that has to move fast but cant cut corners or talking a founder through a hard pivot and helping them separate what theyve already built from where the data says they should actually go. Youll prototype alongside them experiment with frontier AI and carry what you learn from hundreds of founders back into AWS so the products we build reflect what the leading edge actually needs.

We hire for a specific kind of person and it starts with founder empathy over enterprise process. You get that every dollar spent on infra is a dollar not spent on talent or growth that their timeline is measured in months of runway and that theyre emotionally all-in on this idea so you earn trust by genuinely caring whether the team survives rather than by showing off enterprise-grade architecture. That empathy shows up as survival-first thinking: before you recommend anything you understand their runway their burn their signals of product-market fit and their next milestone whether thats demo day a fundraise or a first paying customer.

To advise this well you have to see the full stack of the business letting technical choices product business model runway and the founders own risk tolerance all inform your recommendations because you cant advise on architecture without understanding burn rate. You stay a builder at heart since you dont stop being an engineer when you join this team; you prototype write code and get your hands dirty with new models Bedrock agents and RAG because thats how you stay credible with people who build for a living. And you act as a scout for the future spotting when a single startups tool choice becomes a cohort-wide trend twelve to twenty-four months before the rest of the market then carrying that signal back to AWS product and service teams. You dont have to already be a Solutions Architect to do this. Great people on this team have come from founding-engineer roles senior software engineering AI engineering and traditional SA backgrounds and if youre an excellent builder who loves customers we can teach you the AWS you need.
