The Company

Cape was founded in early 2022 by Palantir and Anduril alums with deep expertise in privacy and national security. While running Palantir’s US national security business, our CEO became passionate about privacy and security on mobile devices. Our mission is to be a force for good in global wireless.

At Cape, we are not just another cellular service provider; we are the architects of a privacy-centric movement that starts with the devices in your pocket. We are building a cellular network that helps citizens, including those responsible for our nation’s security, regain control of their own data.

We believe that where we are, where we go, and whom we are with are among our most personal information and should be kept private. Privacy is not something you achieve by limiting yourself or by doing less, it is a set of features to be built so you can do more. We have raised money from Andreessen Horowitz and other top-tier VCs, and are excited to grow the team.

The Team

We are relentless builders, constantly pushing the boundaries of what's possible and bringing to life ideas that have never before existed. Innovation is at the core of everything we do. At Cape, we trust our team to deliver greatness and empower them to make a profound impact. As a member of our team, you will collaborate seamlessly with our diverse group of talented engineers and other team members, enjoying dynamic interactions with colleagues from across the organization.

The Role

Cape’s platform gives customers end-to-end control of their digital identity, optimizing for resiliency, privacy, and security at every turn. We’re transforming how customers sign up, use, and think about their mobile phones and the privacy implications associated with it. Customers are protected at every level of the communications stack – from the mobile device, through contested infrastructure, to the core of the network itself.

As a Senior Software Engineer at Cape, your mission is to provide connectivity without compromise. Your charge is to build a system that enables resilient, global connectivity with a security & privacy first mind-set that separates our users from the legacy telecom ecosystem. This includes everything from building a best-in-class signalling firewall to identify & mitigate malicious signaling attacks that compromise users' most personal communications, to detection of fake base-stations (cell-site simulators), to detecting and preventing SPAM & Smishing campaigns, and being transparent and alerting users when they may be actively targeted by hackers or nation states.

We’re hiring engineers who are passionate about solving real-world problems, personal privacy, and empowering peers to be autonomous. If you’re motivated to develop reliable, highly performant, and scalable systems, and to design robust APIs and primitives, this role offers the opportunity to make a significant impact on our products and the people who use them. Your day-to-day will constantly change and be filled with ambiguity, but everything you work on has a high impact.

Core Responsibilities

• You will Design and Integrate: Build the core telecommunications infrastructure that provides secure cellular service to our users, ensuring end-to-end data integrity.

• Own the Lifecycle: Take full ownership of the software lifecycle—from problem discovery to solution delivery—for foundational components of our telecommunications stack.

• Set the Bar: Maintain high coding standards by developing guidelines, participating actively in code reviews, and fostering a culture of continuous improvement and knowledge sharing.

• Enable Scale: Build reliable, performant, and scalable systems that enable other product teams to build robust applications without requiring deep domain expertise in the underlying infrastructure.

What We Value

• Autonomy: A proven ability to learn continuously, work independently, and make decisions with minimal supervision.

• Collaboration: Experience brainstorming and iterating alongside product managers and designers.

• Pragmatism: The ability to move quickly while building for the long term. You take a thoughtful, practical approach to solving complex problems, considering tradeoffs and avoiding over-engineering.

• Adaptability: Comfort working in a constantly evolving environment with dynamic objectives and direct user iteration.

• Empathy: The ability to work collaboratively with both technical and non-technical teammates, understanding how technical decisions impact the end user.

• Mission-Driven: A deep-seated belief in the importance of digital privacy and security. You understand that the code we ship has real-world consequences and are driven to build systems that protect and empower users.

• Clearance: Active US Security clearance or the eligibility and willingness to obtain one is beneficial, but not required.

What We Require

• 4+ years of professional software engineering experience.

• A strong foundation in Computer Science, Engineering, or a related technical field, demonstrated through both professional experience and academic pursuits.

• Fluency in a modern backend language such as Golang, Rust, Java/Kotlin, or Python.

• A firm grasp of algorithms, data structures, cloud infrastructure, and distributed systems.

• Strong written and verbal communication skills, including the ability to iterate quickly with teammates, incorporate feedback, and hold a high bar for quality.

We offer competitive compensation that is geo-adjusted based on your location, along with meaningful equity so you share in the value you help create. Our benefits include:

• Stipends for

  • Family-forming needs

  • Gender-affirming care

• Unlimited PTO

Our Culture 

• We are builders, and we choose to spend our time building things that matter. Many of our people have backgrounds in Defense Tech as well as the defense and intelligence community. We build to win.

• We hire excellent people, give them outsized responsibility, and trust them to execute at a high level. Everyone here has a track record of solving hard problems throughout their careers.

• We believe that personal privacy and national security interests are not inherently at odds, and can be reconciled via strong technology.

• We believe that companies exist to build awesome things and take care of their people. Our benefits reflect that– top-tier health care, 401(k) matching, and a generous vacation policy (that we actually use).

• We hire candidates of any race, color, ancestry, religion, sex, national origin, sexual orientation, gender identity, age, marital or family status, disability, Veteran status, and any other status. Achieving diversity across these categories will serve to make our company stronger and our product better.
