## Job description

## About Andrenam

We’re building sonar and sensing systems that bring light to the last dark domain: the ocean. Our team includes alumni from SpaceX, Anduril, ABL, Palantir and Qualia. We build full-stack—from physics to perception to product—with speed, elegance, and an unwavering commitment to the mission.

We believe the maritime domain will define the next century of economics, geopolitics, and global security. We're here to shape it.

## About this role

AndrenaM is seeking a Senior Software Engineer who is passionate about advancing the user experience for autonomy and maritime technology to join us at our office in Washington D.C. This is a unique opportunity to be an early member of our software engineering team, shaping the product from the ground up.

Our main engineering challenge is to develop a real-time data platform that can ingest, process, store, and display data from thousands of autonomous and semi-autonomous marine systems. This system must seamlessly handle a wide variety of sensors, hardware interfaces, data sources, and AI-driven analytics; all with military-grade security and robustness.

In this role

- You will set a new standard for user-facing software for distributed, autonomous maritime systems
- You will take on full ownership of large engineering projects from scratch
- You will tackle diverse engineering challenges, with the opportunity to shape your role over time as an individual contributor or technical leader
- You will work alongside top engineers in software, hardware, and autonomy, contributing to cutting-edge defense technology

## Responsibilities

- Collaborate with hardware, software, and business teams to develop features across the stack, from embedded systems deployed in the field to cloud-based data pipelines and user-facing interfaces
- Lead the development of full-stack, user-facing software products for data management, real-time data visualization, and command and control of autonomous systems
- Actively seek feedback from users and stakeholders to continuously improve the user experience
- Create software integrations with external systems as part of the full-stack products
- Drive technical decisions and contribute to the evolution of our software stack
- Provide mentorship and contribute to a collaborative team culture
- Become a go-to expert for all challenges encountered

## Preferred Qualifications

- Experience with IoT systems, defense tech, or related fields
- Experience working directly with end users to understand requirements, design products, and address feedback
- Proficiency writing/debugging software in Python, TypeScript, React, GraphQL, or related technologies
- Proficiency architecting, developing, and iterating on full-stack software products
- Experience building tools to accelerate testing and development of software systems
- Application of modern data structure, algorithm, and software design best practices in production systems
- Experience integrating software systems with electronics or hardware systems
- Experience managing database systems (SQL and NoSQL)
- Experience handling software in controlled and classified environments
- Excellent problem-solving skills and the ability to work independently in a dynamic, fast-paced environment
- Experience developing roadmaps and communicating timelines with stakeholders of your work
- Previous startup experience, working with non-technical customers, and examples of successfully proposing/delivering 0 to 1 projects

## About Andrenam

## Company Overview
- **One-liner**: Andrenam builds an AI-powered, distributed maritime sensing network using intelligent acoustic buoys to detect, track, and classify underwater activity for defense, energy, and security applications.
- **Entity Type**: Private (Seed + Series A funded)
- **Headquarters**: Hawthorne, California, United States
- **Founded**: 2024
- **Founders**: Matej Cernosek (Co-Founder & CEO)

## Core Business
- **Primary industry**: Defense and Space Manufacturing; Maritime Security; Undersea Intelligence
- **Target customers**: B2B – U.S. Navy and allied defense agencies, commercial maritime operators, energy & offshore companies, counter-UUV units
- **Mission statement**: “Undersea intelligence at scale, anywhere” – democratizing sonar sensing and persistent autonomous awareness from surface to seabed.

## Products & Services
- **PEARL**: A rapidly deployable, mass-manufacturable acoustic buoy that autonomously collects underwater sound data and transmits it via satellite. Designed for persistent, scalable monitoring.
- **OBSIDIAN**: An AI-native software platform that processes, analyzes, and transforms acoustic data into real-time actionable intelligence, delivering alerts and classifications through an operator-friendly interface.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding $28M – $10M Seed (July 2025, led by First Round Capital) and $18M Series A (July 2026, led by Upfront Ventures with participation from Valor Equity Partners, Also Capital, First Round Capital, and Long Journey)
- **Notable Investors/Partners**: First Round Capital, Upfront Ventures, Valor Equity Partners, Also Capital, Long Journey; operational collaboration with U.S. Navy UUV Group 1 (UUVGRU-1)
- **Growth Signals**: 157% year-over-year headcount growth (13 employees as of mid-2026); completed a 2.5-week deployment at the UUV confidence course in Keyport, WA, with zero mission-ending failures; Series A funding to scale manufacturing and team.

## Competitive Advantages
- **Mass-manufacturable buoys** that can be deployed rapidly without specialized crews, lowering the barrier to persistent undersea monitoring.
- **AI-native processing** (OBSIDIAN) that turns raw acoustic data into real-time, actionable alerts – reducing the need for human analysts.
- **Proven real-world performance** with the U.S. Navy, demonstrating reliability in operational environments.
- **End-to-end solution** from hardware (PEARL) to software (OBSIDIAN), creating a seamless, scalable system.

## Strategic Focus
- Scaling production and deployment of PEARL buoys to meet rising demand from defense and commercial customers.
- Expanding the team across engineering, business development, and government programs to support growth.
- Deepening partnerships with U.S. Navy and allied forces, and entering commercial markets (energy, offshore, counter-UUV).

## Why Work Here
- **Culture**: Small teams, fast decisions, meaningful responsibility from day one. “We care more about outcomes than titles.”
- **Work environment**: Remote-friendly with some in-office roles (Torrance, CA). Remote positions include Federal Account Executive, Director, US Government Programs, Director, Commercial Programs. Engineering roles are in-office (Torrance) or remote (Senior Software Engineer - Data Platform listed as remote? Careful: the careers page shows Senior Software Engineer as "Torrance / in-office" but Senior Software Engineer - Data Platform is also listed as Torrance / in-office. The BuiltIn page says "Remote Workspace" for some roles; check: BuiltIn says "Remote Workspace" for Director, Commercial Programs. So hybrid/remote depending on role.
- **Perks**: Working on critical national security technology with real-world impact; opportunity to work alongside engineers from top defense tech companies (Anduril, Saronic, Blue Origin, Arc).
- **Engineering culture**: Emphasis on reliability, hardware-software integration, and solving hard problems in austere environments.
