Sofar is seeking a Principal Scientist in Marine Acoustics to lead the research and development vision for its global ocean sensing network. This role involves developing advanced underwater acoustic capabilities for detection, classification, and localization of underwater objects, as well as creating acoustic maps of the marine environment. The ideal candidate will have deep expertise in marine acoustics, a strong understanding of acoustic propagation and signal processing, and experience translating scientific research into operational products. This position is based in San Francisco, California, USA.
Sofar designs, builds, and deploys ocean sensing networks at a global scale that provide unique observational knowledge of the ocean environment. We are expanding our sensing capabilities into underwater acoustics to detect, classify, and locate underwater objects, and to create an acoustic map of the marine environment. We are looking for a world expert in ocean acoustics to set the research and development vision for Sofar’s underwater acoustics platform.
At Sofar, we use AI tools in our day-to-day work, and we don't expect our hiring process to be any different. Here's how we think about it:
Applying: Write your own first draft — we want to hear your voice and understand your real experience. AI is fine for refining and polishing, not for generating your story.
Take-home assessments: Complete these on your own unless we've explicitly said otherwise. We'll always be upfront about it when AI is allowed.
Interview prep: Go for it. Use AI to research Sofar, practice your responses, and sharpen your thinking before we meet.
During interviews: This is you. We're a small team and we move fast — live conversations are how we get to know you, and we're genuinely curious how you think in real time.
A note on transparency: We're a lean People team, and we use AI to help with things like drafting job descriptions, preparing interview questions, and candidate communications. We don't use it to make hiring decisions — those are always ours.
The through line: use AI to show more of yourself, not less :)
Hybrid work: We're a hands-on team building hardware and software that operates in the real world — so being together matters. We ask that most team members are in office at least 70% of the time, though some roles (like field technicians or hardware engineering) may require more. Fully remote roles are designated as such in the job posting.
Visa sponsorship: We do sponsor visas and retain an immigration lawyer to support the process. While we can't guarantee sponsorship for every role or situation, if we make you an offer, we'll make every reasonable effort to make it work.
A note on applying: We mean it when we say we want the strongest people — not the most credentialed ones. If you're excited about this work but don't check every box, please apply anyway. Research consistently shows that underrepresented candidates are more likely to self-select out, and that's a loss for everyone. Sofar operates at the intersection of ocean science, climate, and technology — the problems we're solving are consequential, and the perspectives we bring to them matter. We're actively working to build a team that reflects that.
We at Sofar Ocean acknowledge that careers in the marine sciences “... have traditionally been, and remain, non-diverse work environments”, thereby limiting the entry and prosperity of underrepresented groups in the space. (Johri et al., 2021) Many of these same groups are disproportionately affected by climate change, and are often excluded from decision making that directly address their interests and needs.
We are committed to addressing these climate injustices and highly encourage people who identify as women, LGBTQ+, Black, Indigenous, and people of color (BIPOC) to apply.
