Job Title: Senior Product Manager
Location: On-Site (San Leandro, CA)
Job Type: Full-Time
Role OverviewSirenOpt is looking for a
Senior Product Manager to own the product experience through which our customers understand their materials. This is a customer-obsessed, hands-on product role. You will spend significant time in the field with process engineers, technicians, and quality managers, mapping their workflows in detail, understanding where our product creates value, and translating that understanding into a complete hardware and software experience that is intuitive, reliable, and genuinely delightful to use.
Our software is how customers get their answers. Making it simple, clear, and sticky is the core of this role. You will lead the design of user workflows and interfaces, prototype and test them directly with users, and define the product experience across our standalone and inline offerings. You will work closely with engineering, data science, and commercial teams, and partner directly with the Head of Product on roadmap and product direction.
What You'll DoCustomer & User Understanding- Spend substantial time in the field understanding how customers work: their processes, their pain points, and how our product fits into their day-to-day.
- Map user workflows in detail across personas i.e. technician, process engineer, quality manager, and distinguish stated needs from latent ones.
- Build and maintain a deep, structured understanding of user needs that informs every product decision.
Product Experience & Design- Own the end-to-end software product experience, designed first for non-expert users who need clear, actionable answers without deep metrology, machine learning or software training.
- Use Figma or equivalent tools to personally prototype and test interface concepts and workflows with real users before involving engineering.
- Systematically simplify: reduce the number of steps, parameters, and decisions a user faces, working with engineering to hide or automate complexity that should not be user-facing.
- Define how measurement results and analytics are presented to each persona, communicating confidence and uncertainty in plain language.
Product Definition & Collaboration- Translate customer and user understanding into clear product definition and feed it into the requirements process owned by engineering through active collaboration.
- Partner with data science and machine learning teams to shape how the analytics layer serves non-expert users, including reducing manual model training as a user-facing step.
- Contribute customer and product insight to the roadmap and product direction led by the Head of Product.
- Prioritize Jira tickets for product workstreams and facilitate planning with engineering, and commercial teams.
What We're Looking For- BS or MS in Human-Computer Interaction, Interaction Design, physical sciences or engineering
- 5 to 10 years in software product management or UX/product design, with at least 3 years owning a software product experience end to end
- Hands-on UX and UI design ability: a portfolio of interface work you personally produced and tested in Figma or equivalent tools
- A track record of deep customer and user research - spending time in the field, mapping workflows, and translating observation into shipped product decisions
- Demonstrated ability to take complex or technical products and make them simple and intuitive for non-expert users
- Experience with ML or analytics platform products: presenting model outputs to non-expert users and managing features with non-deterministic behavior
- Proficiency with Jira and Agile practices
Nice to have:- Experience designing software for industrial, scientific instrumentation, or non-destructive testing applications
- Background in or exposure to battery manufacturing, aerospace coatings, or semiconductor materials
- Experience with software deployed in industrial or manufacturing environments
- Willingness to travel to customer sites in North America, the United Kingdom, Europe, and Asia
- Prior experience at an early-stage deep-tech startup
Base Pay Range
$155,000-$190,000 USD
Benefits- Equity and Salary compensation depends on experience
- Health, Dental, Vision plans provided
- 401k matching provided
- Time off: 20 days of PTO per year, plus approximately 15 paid US holidays per year
