What does a Sr Embedded Software Engineer do?

A Sr Embedded Software Engineer designs, develops, tests, and maintains software that runs on embedded systems such as microcontrollers, sensors, and specialized hardware. They work closely with hardware engineers to ensure seamless integration between software and hardware components. Their responsibilities often include writing code in languages like C or C++, debugging and troubleshooting embedded systems, and optimizing software for performance and resource constraints. Senior engineers may also mentor junior team members and contribute to system architecture decisions.

What are the key skills and qualifications needed to thrive as a Sr Embedded Software Engineer?

To thrive as a Sr Embedded Software Engineer, you need strong proficiency in C/C++ programming, embedded systems design, and a relevant engineering degree such as Electrical or Computer Engineering. Familiarity with real-time operating systems (RTOS), microcontrollers, debugging tools, and certifications like Certified Embedded Systems Engineer are often expected. Excellent problem-solving, attention to detail, and effective communication skills set top candidates apart. These capabilities are crucial for developing reliable, efficient embedded solutions and collaborating across hardware and software teams.

What are some common challenges faced by Sr Embedded Software Engineers when working on cross-functional teams?

Sr Embedded Software Engineers often collaborate with hardware engineers, systems architects, and QA teams to deliver integrated products. A common challenge is ensuring seamless communication across disciplines, as hardware and software timelines may not always align. Troubleshooting issues that span both hardware and software layers requires strong problem-solving skills and adaptability. Effective documentation and regular cross-team meetings help mitigate misunderstandings and keep projects on track.

What is the difference between Sr Embedded Software Engineer vs Embedded Software Engineer?

AspectSr Embedded Software EngineerEmbedded Software Engineer
Required CredentialsBachelor's/Master's in CS, EE; 5+ years experienceBachelor's in CS, EE; 1-3 years experience
Work EnvironmentDesign, develop, and troubleshoot embedded systems in hardware-focused teamsDevelop embedded software, often under supervision, in similar environments
Employer & Industry UsageTech, automotive, aerospace, consumer electronicsSimilar industries, often entry to mid-level roles

The main difference between a Sr Embedded Software Engineer and an Embedded Software Engineer lies in experience, responsibilities, and expertise. The senior role typically involves leading projects, designing complex systems, and mentoring junior staff, while the embedded software engineer focuses on developing and testing embedded code. Both roles are vital in industries like automotive, aerospace, and consumer electronics, but the senior position requires more experience and a broader skill set.

Are Sr Embedded Software Engineers in demand?

Senior Embedded Software Engineers are in high demand due to the growth of IoT, automotive, medical devices, and industrial automation sectors. They typically require expertise in C/C++, real-time operating systems, and hardware integration, making their skills highly sought after in technology-driven industries.

Job 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.

What You Will Do
  • Develop and maintain real-time embedded C/C++ code for core components of OceanComm's acoustic modem firmware, owning features from concept through deployment
  • Provide technical leadership through exemplary code and design judgment that others trust and want to 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 test, 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

Requirements

  • B.S. or M.S. in Electrical Engineering, Computer Engineering or related discipline
  • 5+ years of experience developing embedded real-time systems with C/C++ 
  • Proficiency in developing DSP software for real-time systems
  • Solid knowledge of linear algebra, signal processing theory, algorithms, and implementation techniques (filters, transforms, synchronization, estimation, etc.)
  • Experience drafting technical documentation
  • Strong written and verbal communication skills
  • U.S. Person
What Will Put You Ahead
  • Experience with underwater acoustic communications, sonar, modem design, SDR, RF communications, or similar signal-processing systems
  • Experience optimizing DSP 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, e.g., low-noise amplifiers, analog-to-digital converters, and integrated analog-front-ends

Benefits

  • Competitive base salary and incentive stock options
  • Paid vacation starting at 20 days per year, increasing with tenure
  • 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.

OceanComm is an Equal Opportunity Employer, including disability/vet.
