Liquid Instruments - Senior Product Marketing Engineer, Quantum

Liquid Instruments is hiring a Senior Product Marketing Engineer to lead its expansion into quantum sensing, metrology, and networking. The role defines market priorities and messaging, develops technical proof and go-to-market materials, enables Sales, and brings customer evidence to Product Management and R&D.

Responsibilities:

• You'll define the quantum segments and applications where Liquid Instruments leads, across sensing, metrology, timing, networking, and laser-oriented quantum research. You'll support Product Management in sizing the dollar opportunity in each segment so we invest where the return is greatest. You'll map how national labs, university groups, defense research teams, and venture-backed quantum startups buy. You'll bring leadership a clear recommendation backed by evidence
• You'll support Product Management in tracking competitors' products, pricing, positioning, and roadmaps. You'll turn that analysis into deal-level guidance on where Moku wins and into sharper messaging, treating what competitors build as a signal of what customers are asking for
• You'll own vertical and product-level messaging for quantum, built on our existing company messaging framework. You'll validate it with working researchers and make sure Marketing and Sales use it consistently
• You'll write application notes, white papers, and benchmark data that establish Liquid Instruments in quantum labs. Topics include PDH and cavity locking, laser linewidth and phase noise characterization, feedback loop performance, multi-channel phase measurement, and time and frequency analysis
• You'll own the technical go-to-market for new quantum products, from positioning to sales enablement to launch content
• You'll build the training content, competitive battlecards, and demos for our Sales team, application engineers, and channel partners. The goal is for them to lead a credible conversation with a quantum research team. You'll support strategic opportunities hand in hand with Sales
• You'll bring organized evidence from quantum customers to Product Management and R&D. You'll make the case for the instrument capabilities, performance specs, and software features this market needs
• You'll work with quantum research teams in their labs to run measurements, give demos, and lead technical sessions. You'll represent Liquid Instruments at key events and publish and present as part of the role. Expect about 10–20% travel
• You'll work closely with the Content, Field Marketing, and Design teams. They own the blog calendar, social channels, website production, and event logistics

Requirements:

• 8+ years of combined research and commercial experience, including time in product marketing, product management, applications engineering, application science, or another customer-facing technical role
• Direct hands-on experience in one or more of: atom interferometry, optical or atomic clocks, NV-center or Rydberg sensing, frequency combs, laser frequency stabilization, quantum networking, or precision timing and frequency transfer
• Fluency with the instruments this work depends on: lock-in amplifiers, PID and laser lock controllers, phasemeters, spectrum analyzers, arbitrary waveform generators, and FPGA-based control
• Experience supporting market sizing and competitive analysis
• Understanding of competitors in this market, including Zurich Instruments, Toptica, Vescent, Stanford Research Systems, and in-house FPGA solutions
• A track record of bringing a technical product into a research market, from strategy through execution
• Able to lead work across teams without formal authority
• Comfortable with ambiguity and fast-moving work
• PhD in Physics, AMO, Quantum Optics, Electrical Engineering, or a closely related field strongly preferred
• MS with equivalent hands-on research experience considered
