The posting

About Base

Base is America’s next-generation power company. We’re rebuilding the foundation of modern civilization–electricity–by deploying a vast network of distributed batteries that is transforming today’s fragile, centralized grid into a resilient and abundant system. We are engineers, operators, and creatives solving some of the most complex, interdisciplinary challenges of our time.

About the Role

Base's batteries are internet-connected industrial control systems in miniature. Installed across thousands of homes, together they operate as a distributed power plant. The attack surface runs from silicon to cloud.

You'll own the end-to-end security of the fleet and how it interacts with the world. The fleet is live today and scaling quickly, so the exposure is real and compounds with every install. This is a generalist role: you'll go wherever the risk is highest, across software, firmware, hardware, and cloud. You'll dive into unfamiliar systems, bottom out assumptions, and prove what's actually true.

What You'll Do

  • Own threat modeling and design review across the product, from gateway SoCs and boot chains through embedded firmware, fleet transport, command authority, and cloud services
  • Turn threat models into prioritized security objectives and drive their implementation
  • Design and build the security foundations under the fleet: device identity and factory provisioning, code and OTA signing, service authentication, and certificate lifecycle across devices that outlive the systems issuing them
  • Analyze vulnerability reports and internal findings: reproduce them, run variant analysis, determine exploitability and design impact, and set the direction of the fix
  • Test our product the way an attacker would, at whichever layer matters, then turn findings into requirements and standards changes
  • Author security engineering standards and reference patterns, build the tooling that makes review and enforcement repeatable
  • Produce the technical assessments Base's position rests on in utility, interconnection, and certification engagements where device security is in scope

What You'll Bring

  • Experience securing production systems that span multiple trust boundaries
  • A track record of shipping security work end-to-end and collaborating across teams to make it stick
  • The judgment to distinguish plausible attacks from consequential ones and prioritize accordingly
  • The ability to get productive quickly in unfamiliar systems, bottom out assumptions, and support conclusions with evidence
  • Enough software engineering depth to read, test, and change the systems you review, regardless of language or tech-stack
  • Clear communication and writing skills - ability to rally other teams

About the Team

Base's Product Security team owns the security of a fleet that's already live in thousands of homes and scaling fast, from the SoCs and boot chains inside each battery to the cloud services commanding them. The team is small and generalist by design. Rather than splitting into narrow specialties, its engineers go wherever the risk is highest, moving fluidly across firmware, hardware, software, and cloud. That range matters because Cortex is shipping today with almost no security review and years of accumulated debt across gen1 and gen3. The team's job is equal parts establishing what's actually true about the fleet's current state and building the lasting foundations, like device identity, signing, and certificate lifecycle, that let it keep scaling safely.

Please note: Base is a startup, which means priorities shift and evolve quickly. Your role may expand or change based on the needs of the business at any given time, so the responsibilities listed may not be exhaustive.

Our Values

  • First Principles Thinking: Question assumptions. Principles > rules.
  • Operate at Base Pace: Focus on what matters, act quickly, and learn by doing.
  • Give & Get Feedback: Be direct, be humble, and maintain a growth mindset.
  • Everyone’s an Owner: Follow through on commitments and own results.
  • Strong Opinions, Loosely Held: Drive clarity and make calls with imperfect information.
  • Committed to the Mission: Rebuilding the grid is a big challenge. We work hard because we care deeply about the impact we’re creating. We work in-person. It’s not a 9-to-5. We are all-in.
  • Fun & Optimism Coexist with Grit: Collaboration and celebration coincide with the intensity of building real things.

Do the best work of your life at Base.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
