Description

About Vatn Systems
Vatn Systems is an innovative startup at the forefront of designing and manufacturing autonomous underwater vehicles (AUVs). Our mission is to revolutionize underwater security, exploration, research, and operations through cutting-edge technology and unparalleled engineering. Our AUVs are defining the next generation of underwater autonomy.

Summary
We are seeking a talented and highly motivated Senior Electrical Engineer / Senior Computer Engineer to take on a leadership role in the electronic system design & analysis, schematic capture, and PCB layout within our fast-paced and innovative AUV startup.

As a senior member of our engineering team, you will own the design, development, analysis, and optimization of electrical systems and PCBs for our cutting-edge AUV technology, while mentoring junior engineers and driving key architecture decisions that shape our undersea superiority.

Key Responsibilities

  • Contribute to the design and implementation of all things electronic on our present and future products, driving architecture decisions in collaboration with the Electrical Engineering team and all other engineering departments
  • Complete schematic capture and layout of high-quality, complex PCBs, considering signal integrity, power distribution, thermal management, and manufacturability
  • Research, evaluate, and select electronic components, including microcontrollers, sensors, connectors, and power management devices, ensuring they meet performance, reliability, and environmental requirements
  • Develop wiring diagrams and harness designs for in-house and external fabrication
  • Design and execute rigorous testing plans to validate the functionality, performance, and reliability of the electrical systems, firmware, and PCBs internally developed and externally procured. Identify and resolve any issues or anomalies that arise during testing.
  • Create & maintain detailed documentation, including specifications, interface control documents, test procedures, and manuals
  • Collaborate effectively with cross-functional teams, including software engineers, mechanical engineers, and project managers, to ensure successful project execution. Communicate technical concepts and ideas clearly to both technical and non-technical stakeholders.
  • Stay updated with the latest advancements in relevant tools, technologies, and practices. Identify opportunities to enhance system performance, reduce cost, reduce complexity, and increase manufacturability
  • Responsible for a successful Engineering to Manufacturing handoff when transitioning R&D efforts into manufacturable product
  • Provide technical guidance and mentorship to junior and mid-level engineers, reviewing designs and supporting their growth

Required Qualifications

  • Bachelor's or Master’s degree in Electrical Engineering or Computer Engineering
  • 7+ years of experience in electrical or computer engineering roles, with a focus on electrical system design & PCBs; experience in the Marine Industry and/or Robotics Industry highly desirable
  • Strong proficiency with PCB design tools (Altium Designer) and deep familiarity with PCB fabrication/assembly processes
  • Strong understanding of analog and digital circuit design as well as AC / DC power electronics. Experience with simulation tools such as SPICE
  • Excellent analytical and problem-solving skills, with the ability to work under tight deadlines and manage multiple tasks simultaneously
  • Strong teamwork and communication skills to collaborate effectively within a multidisciplinary team environment and engage with external partners and suppliers
  • Comfortable working in a dynamic startup environment with changing priorities. Self-motivated with a passion for innovation and learning.
  • Demonstrated ability to mentor junior engineers, lead technical discussions, and drive design decisions independently

Preferred Qualifications

  • Prior experience in a startup or fast-paced product development environment
  • Experience with embedded firmware development (C/C++) on platforms such as Microchip dsPIC and STM STM32, and digital communication protocols (UART, SPI, I2C, CANbus, Ethernet, etc.)
  • Experience with energy storage systems (such as Lithium-Ion Battery Packs) and both low & high voltage DC systems (12V to 800VDC)

Vatn is an equal opportunity employer. 

About this role

Vatn Systems is building autonomous underwater vehicles, and they're looking for a senior electrical engineer to lead the design and development of the electronic systems that make these machines work. You'd own the full lifecycle of PCB and electrical architecture—from component selection and schematic capture through layout, testing, and manufacturing handoff. This is a hands-on role where you'll make key technical decisions, collaborate across mechanical and software teams, and mentor junior engineers as the company scales.

The position requires at least seven years of electrical or computer engineering experience with a strong foundation in PCB design (Altium), analog and digital circuits, and power electronics. Marine or robotics industry background is valued but not required. You'll need to be comfortable with simulation tools, rigorous testing methodologies, and the practical side of manufacturing—translating designs into products that actually get built. The startup environment means priorities shift and you'll wear multiple hats, but it also means your contributions directly shape the technology.

If you thrive in fast-paced settings, have deep PCB expertise, and want to work on specialized hardware in an emerging field, this role offers real technical leadership and ownership. Experience with embedded systems, high-voltage DC power, or battery management systems would strengthen your candidacy, though the core requirement is proven electrical design and the ability to lead a team.
