## Job description

Logos Space is a Low Earth Orbit (LEO) satellite system purpose-built to serve the connectivity needs of the commercial enterprise users and government users. We will help fill an important gap in the market, providing resilient, high-performance satellite-based connectivity services to enterprise and government customers worldwide. Business customers have contracts with agreed-upon performance standards for their broadband, and Logos will build these capabilities into the system from the beginning. Speed and reliability are the foundation of the system. Logos is designed to extend cloud and data center network connectivity anywhere in the world to fixed, seaborne, and airborne terminals.

Logos is led by a team of highly experienced engineers with proven track records in the networking and satellite industries.

## About Logos Space Engineering

The Product and Data Link Security team at Logos Space Engineering is responsible for ensuring the success of our network by providing unique levels of security and authentication in space communications. This position is a critical driver of the architecture, overseeing development efforts specific to the security architecture, as well as working with other teams like ground segment and spacecraft systems.

We are seeking engineers who can thrive in a fast-moving environment, comfortable taking vague design ideas and turning them into concrete, testable architecture and secure solutions.

The Role:

The Lead Security Engineering - Terminals will have technical ownership of the end-to-end security design and delivery of our novel ground-based terminals. This role is responsible for the security architecture of terminal systems including mmWave apertures, complex RF and switching subsystems, and baseband hardware. You will ensure embedded security and secure wireless communication for the ground segment, defining and enforcing the security guardrails for what Logos procures and manufactures.

## Key Responsibilities

- Develop and maintain a comprehensive security strategy and roadmap for ground-based terminal hardware and software interfaces.
- Design and implement RF-related datalink security and secure wireless communication protocols for terminals.
- Conduct thorough threat modeling across terminal hardware components, including mmWave and baseband subsystems, and low-level software interfaces.
- Lead the design and implementation of secure provisioning workflows and key injection for terminal hardware components.
- Ensure alignment with cryptographic standards such as FIPS for terminal security modules.
- Oversee manufacturing security and manage the chain of custody for terminal production to prevent tampering.
- Collaborate with Terminal Hardware and RAN Stack teams to integrate security controls into the terminal architecture.
- Provide technical guidance and mentorship to security engineers, contributing to the overall growth of the security organization.
- Oversee secure boot, firmware security, cryptographic lifecycle management, anti-tampering, aecure onboarding for the terminal systems.
- Note: This will be a hands-on role with a scope to potentially build a team.

## Basic Qualifications

- Bachelor's degree in Computer Science, Electrical Engineering, Cybersecurity, or a related field (Master's degree preferred).
- Minimum of 7-10 years of experience in security engineering, with demonstrable experience in designing and implementing security solutions for embedded systems or complex hardware.
- Ability to program in C/C++/Rust and scripting languages like Python.
- Strong knowledge of security principles, best practices, and frameworks (e.g., Zero Trust, defense-in-depth).
- Excellent analytical, problem-solving, and troubleshooting skills.
- Ability to work independently and as part of a collaborative team in a fast-moving environment.

Must-Have Skills

- Embedded security for ground terminals, network security
- RF related datalink security and secure wireless communication
- Threat modeling across terminal hardware and software interfaces
- Compliance experience with standards like FIPS, Common Criteria, CSfC
- Good knowledge of manufacturing security and secure provisioning for terminal hardware

## Preferred Qualifications

- Experience with mmWave apertures, RF/baseband subsystems, and SDR MAC/PHY interactions.
- Relevant security certifications such as CISSP, CISM, or equivalent.
- Experience with automation for hardware security testing tasks.
- Ability and willingness to attain a Top Secret Clearance.
- Experience with 4G/5G RAN systems, wireless infrastructure, SATCOM security, PDCP, IPSEC or MACSEC.

## About Logos Space

## Company Overview
- **One-liner**: Logos Space is building a low Earth orbit (LEO) satellite constellation to deliver a secure, resilient, high-performance private network for government and enterprise customers.
- **Entity Type**: Private (Series A)
- **Headquarters**: Mountain View, California, USA (with additional office in Redwood City, CA)
- **Founded**: 2024
- **Founders**: Milo Medin (former Google VP of access services and NASA project manager)

## Core Business
- **Primary industries**: Satellite communications, aerospace & defense, telecommunications
- **Target customers**: Government agencies (defense, intelligence, civil) and large enterprises requiring secure, guaranteed connectivity – distinct from consumer-focused satellite broadband.
- **Mission / purpose**: Deliver a next-generation private network that is purpose-built for contested communications environments, offering security, resilience, and fiber-like performance where fiber doesn’t go.

## Products & Services
- **Logos LEO Constellation**: A planned network of up to 4,178 satellites operating in Q, V, Ka and E frequency bands (FCC licensed). Capabilities include symmetric multi-gigabit throughput, Layer 2 MPLS networking, end-to-end encryption, and electronic warfare (EW) resilience. Designed as a dual-use system (civilian and military) with hardened satellites and a mesh architecture to maintain service during disruption.

## Market Standing
- **Valuation/Total Funding**: USD $50 million (Series A led by US Innovative Technology Fund, announced June 2025). Total funding to date is $50M, with USIT as the sole investor.
- **Key Metric**: 22–38 employees (rapidly growing; headcount up 416% year-over-year); 59 active job postings as of mid-2026.
- **Notable Investors / Partners**: US Innovative Technology Fund (chaired by serial entrepreneur Thomas Tull). Key hires from SpaceX, NASA, Airbus, OneWeb, and Apollo Fusion.
- **Growth Signals**: FCC grant for satellite spectrum license (Feb 2026) authorizing up to 4,178 satellites; emerged from stealth in Oct 2024; aiming for first operational satellite in late 2027; aggressive hiring across engineering, RF, software, and business development.

## Competitive Advantages
- **Dual-use focus**: Purpose-built for government and enterprise, not consumer – enabling higher security, guaranteed service, and resilience requirements.
- **EW-resilient design**: Architecture minimizes signal disruption and resists jamming through high-elevation angles, tightly focused beams, and hardened satellites.
- **Unique spectrum portfolio**: FCC-approved use of Q, V, Ka and E bands – high-frequency bands that are less congested and offer higher bandwidth.
- **Fiber-like performance at scale**: Symmetric multi-Gbps throughput with Layer 2 MPLS and end-to-end encryption, filling a gap underserved by existing LEO providers.
- **Experienced leadership**: Founder Milo Medin (Google access services, NASA) and a deeply experienced technical team from top aerospace and satellite organizations.

## Strategic Focus
- Complete critical design decisions, select partners, and build prototypes.
- Scale engineering team from ~30 to 70+ employees through 2026.
- Deploy first operational satellite by late 2027 and begin constellation build-out.
- Continue engaging with U.S. regulators and potential government/enterprise customers.

## Why Work Here
- **Mission-driven**: Work on a “next-generation” communications infrastructure that addresses real national security and enterprise resilience needs.
- **Culture & values**: No silos, no politics; treat people with respect; debate, decide, commit; continuous learning; customer focus. Operating principles explicitly discourage unprofessional behavior.
- **Growth opportunity**: Start-up stage with significant funding, clear milestone, and aggressive hiring – opportunity to shape technology and team.
- **Work policy**: In-office (typically 5 days a week) at Mountain View or Redwood City, CA locations.
- **Teams**: Engineering, product, operations, and business development roles heavily represented; emphasis on space, RF, embedded software, and network engineering.
