Telecommunications Architect

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 is seeking a Wireless Network Architect who combines deep expertise in planning, building, and operating cellular networks with the vision and courage to disrupt legacy approaches and reimagine the future of telecom. You’re not just an expert in telecom architecture—you’re driven to make an impact. You want to join a fast‑growing company where your work directly supports the U.S. and its allies in strengthening national security. This is an opportunity to contribute to projects that truly matter—shaping the geopolitical landscape in an era where telecom is an essential element of modern warfighting.

In this role, you’ll bring the technical depth to go toe‑to‑toe with vendors, partners, and internal teams as we implement a next‑generation, cloud‑based Core network. You understand IMS, packet cores, and the edge elements that integrate with other networks—including 4G and 5G variants such as HSS, UDM, and UDR.

You are both an architect and a builder: capable of seeing the big picture and inventing what’s next, while unafraid to roll up your sleeves and execute. This is a hands‑on role where strategy and delivery go hand in hand. This position reports directly to the Head of Engineering .

How You’ll Make an Impact (Outcomes of the Role)

• Design and deliver core networks that support essential features (voice, data, messaging), address customer use cases, and solve hard problems with novel, never‑been‑done solutions—while ensuring scale and reliability.

• Partner across teams and vendors to stitch together solutions and bring them successfully to market.

• Implement new features with zero disruption to live users through well‑planned MOPs, maintenance windows, test plans, and phased rollouts.

• Troubleshoot deeply—dig into network traces with partners and vendors to isolate root causes and resolve complex issues.

• Interconnect networks—from private to commercial, roaming to MVNO—ensuring seamless interoperability.

• Drive new standards in security and privacy, whether by encrypting data, eliminating unnecessary storage (e.g. CDRs), augmenting 3GPP/GSMA functions, or inventing new protections against malicious actors.

• Stand up new network instances in new regions or with functionality tailored to evolving customer needs.

What We’re Looking For (Requirements)

• 4+ years wireless Core network architecture experience, including IMS, EPC/PGW, MME, HSS, SGW (or 5G equivalents).

• Hands‑on operational skills—comfortable deploying, configuring, and debugging network functions in a startup environment.

• Deep expertise in telecom features such as VoLTE/VoNR, VoWiFi, SMS/MMS over IP, and regulatory compliance (e911, NG911, CALEA).

• Familiarity with 4G, 5G NSA, and 5G SA architectures.

• Strong protocol knowledge: Diameter, SIP, GTP, and related cellular network protocols.

• Vendor management experience, with the ability to hold external partners accountable.

• Design documentation skills, from high‑level architecture to detailed network diagrams.

• Comfort with disruption—willingness to do things differently than legacy telecom approaches.

• Preferred experience:

  • Cloud‑based network deployments

  • Launching MVNOs, roaming interconnects, IPX, trunking, and cross‑network connections

  • RAN expertise and/or knowledge of SIMs, SIM applets, and OTA platforms

Role Competencies

• Wireless Core Network Expertise – Ready to hit the ground running with deep technical knowledge.

• Innovation – Able to spot opportunities for disruption and differentiation in a legacy‑heavy industry.

• Mission‑Oriented – A team player who thrives in collaborative, goal‑driven environments.

• Customer‑Centric – Designs networks that meet and anticipate customer needs, with innovations that delight.

• Flexible & Adaptable – Comfortable with the speed and unpredictability of a growth‑stage startup.

• Zoom In / Zoom Out – Big‑picture strategic thinker who can also dive deep into details.

• Sense of Urgency – Operates at startup pace; proactive and resourceful.

• Clear Communicator – Can document technical designs, draft specifications, and translate complexity for non‑technical audiences.

Additional Details

• Travel: Extensive, including international, especially during the first 6 months.

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.
