About the Job

Requirements

A B.S. or M.S. in Electrical Engineering, Computer Engineering, or a related discipline is required.
At least 5 years of experience developing embedded real-time systems with C/C++ is required.
Proficiency in developing digital signal processing software for real-time systems is required.
Solid knowledge of linear algebra, signal processing theory, algorithms, and implementation techniques, including filters, transforms, synchronization, and estimation, is required.
Experience drafting technical documentation is required.
Strong written and verbal communication skills are required.
U.S. Person status is required.

Responsibilities

Develop and maintain real-time embedded C/C++ code for core components of the acoustic modem firmware, owning features from concept through deployment.
Provide technical leadership through exemplary code and design judgment that others trust and can build on.
Implement, optimize, and validate advanced acoustic signal processing algorithms.
Collaborate with electrical, mechanical, systems, and field teams to define interfaces and verify system performance.
Develop tests, tools, and procedures for firmware validation, hardware bring-up, production testing, troubleshooting, and repair.
Help evaluate tradeoffs in performance, reliability, complexity, schedule, cost, and risk.
Help improve engineering culture, communication, and technical standards as the team grows.

Desired Qualifications

Experience with underwater acoustic communications, sonar, modem design, software-defined radio, radio frequency communications, or similar signal-processing systems.
Experience optimizing digital signal processing algorithms for embedded platforms, including fixed-point, floating-point, memory, latency, or power constraints.
Experience with machine learning models deployed on embedded platforms.
Experience designing domain-specific deep neural networks.
Experience with analog and mixed-signal integrated circuits, such as low-noise amplifiers, analog-to-digital converters, and integrated analog front ends.

Senior Embedded Software Engineer, DSP

OceanComm, Inc. · Chicago, United States · Full-time · Posted 2026-06-30

Salary: USD 140,000–175,000

Workplace: on_site

Department: Research & Development

Description

Underwater communication is one of the hardest wireless problems on Earth. Radio waves attenuate quickly underwater, so our systems use sound, much like whales and dolphins, to transmit high-bandwidth data, including video. We are looking for engineers excited by challenging embedded DSP problems where algorithms, firmware, electronics, mechanics, and real-world operating conditions all have to work together.

This is a high-ownership role on a small, quickly growing team. You will not be one engineer among hundreds working on a narrow subsystem; you will have direct visibility into the full product, from modem firmware and acoustic signal processing to undersea drones and customer deployments.

About Us

Underwater, the wireless transfer of a single picture used to take an hour. OceanComm brought to market wireless modems that transfer data 100 to 1,000 times faster. Legacy modems were largely status and command links; our modems can control undersea drones with live video feedback, fundamentally changing what operators can see, decide, and do underwater. Leading organizations in defense, offshore energy and oceanographic research rely on OceanComm to keep their undersea systems connected.

Paid sick leave with carryover
Flexible schedule with core hours
Close mentorship from experienced engineers and technical leaders
Professional development support for conferences, books, courses, or technical training
Hands-on work with advanced acoustic, embedded, and undersea robotics hardware

Compensation

The pay range for this position is $140,000 – $175,000 per year. Actual pay will depend on the candidate’s experience and skills demonstrated during interviews and other evaluations.

About the Company

OceanComm

Acoustic modem enabling wireless subsea data

OceanComm builds high-speed wireless underwater communication systems. Its main product is an acoustic-wave modem that sends data through seawater using ultrasound, replacing radio signals and working with existing Ethernet networks to enable features like live video from subsea environments and tetherless control of ROVs. The company differentiates itself with much higher underwater data rates and patented signal-processing algorithms, offering subsea networking solutions that connect marine assets to standard networks. Its goal is to reduce operating costs for offshore clients by providing real-time data, video streaming, and remote control of underwater equipment.
