Jobs at Monarch Quantum, Inc.

Design, build, align, and characterize free-space and fiber-coupled laser systems for AMO and quantum sensing. Implement frequency stabilization and servo controls, architect optical and opto-electronic subsystems, translate physics requirements into engineering designs, procure and qualify components, maintain engineering documentation, ensure laser safety compliance, and collaborate closely with AMO physicists and engineers to support experiments and system integration.

Technical owner for characterization, qualification, and reliability testing of photonic components and modules. Design and build test setups, execute DOE-driven experiments, measure optical metrics (power, phase noise, RIN, nonlinearity, beam parameters), run EVT/DVT/PVT verification, perform life testing and failure analysis, generate lab-quality data and engineering reports, and build automated test sequences using Python/LabVIEW/MATLAB to drive product development and production readiness.

Senior individual-contributor responsible for designing and implementing automated test infrastructure, performing device- and system-level opto-electronic characterization (L-I-V, spectral, beam quality, noise, LIDT), developing validation and environmental test protocols, ensuring regulatory and laser-safety compliance, authoring test documentation, and providing technical leadership and guidance across development and production.

Build, align, and maintain free-space and fiber-coupled optical setups to measure and characterize photonic integrated circuits. Develop Python-based automated test infrastructure, acquire data from lasers, OSAs, VNAs, scopes and SMUs, and apply statistical methods to validate designs and ensure repeatable wafer-scale measurements. Document procedures and feed measurement insights back to design and fabrication teams.

The Senior PCB Layout Engineer will manage complex PCB designs, ensuring signal integrity and manufacturability while collaborating with cross-functional teams. Responsibilities include defining routing strategies, conducting design reviews, and generating fabrication documentation, all within a dynamic startup environment.

Lead supplier quality for optics, micro-electronics, fiber optics, and exotic metal components. Perform drawing/GD&T reviews, FAIs, supplier audits, root-cause analyses and CAPA (8D), track quality metrics, support NPI qualification, and drive DFx with internal teams to ensure supplier readiness and production delivery.

Lead a multidisciplinary photonics systems engineering team to define and deliver end-to-end photonics system architectures. Own requirements flowdown, architecture trade studies, risk-reduction experiments, validation plans, customer technical engagement, and cross-functional integration to enable scalable, manufacturable, and reliable production systems.

Lead development of Monarch's supplier quality architecture and QMS, own technical supplier commodities, drive NPI/APQP and DFx, perform supplier audits and FAI/PPAP, lead CAPA and root-cause analysis, monitor supplier metrics, and partner cross-functionally to scale production quality for optics, electronics, fiber, and exotic-metal components.

The Senior Principal Project Engineer leads project development in photonics, managing team dynamics and ensuring successful execution while employing best practices and anticipating risks.

The Optical Systems Engineer designs and executes testing for photonic systems, mentors junior engineers, and collaborates on risk assessment and system design.

Lead hands-on photonics process development and scale-up including wire and die bonding, vacuum reflow, fiber splicing, optics attachment and active alignment. Design DOEs, improve yield and reliability, develop process documentation, support qualification and pilot manufacturing, perform root-cause analysis, collaborate with vendors, and train technicians to transfer R&D processes into repeatable production.

The Principal Firmware Engineer will design FPGA-based solutions, mentor junior engineers, manage project scopes, and collaborate across teams to enhance embedded systems.

The Optical Engineer will execute complex engineering tasks, mentor junior engineers, and ensure the accuracy of execution schedule and data quality while engaging with team members and leadership.

The Optical Engineer Level 2 will execute complex engineering tasks, mentor junior engineers, and support optical design and modeling efforts in a startup environment.

Lead development projects in photonic systems, ensuring project scope, schedule, and budget adherence while managing teams and risks effectively.

Lead architecture, design, and integration of advanced laser and photonics systems for quantum technologies. Define core photonics and control technologies, achieve ultra-low noise and high reliability through modeling and experimental validation, collaborate with cross-functional engineering teams, maintain system requirements and validation protocols, and mentor junior engineers to drive technical excellence and scalable engineering practices in a startup environment.

The Robotics Process Engineer 3 will handle engineering tasks, drive innovation in design and analysis, and support project engineering within a startup environment.

The role focuses on technical leadership in designing and integrating advanced laser systems for quantum technologies, mentoring engineers, and aligning technical development with business goals.

As a Principal Optical Engineer, you'll lead optical design projects, ensure data integrity, and drive innovation, while working independently and collaboratively in a startup environment.

Lead end-to-end technical programs from proposal through production, owning scope, schedule, and financials. Coordinate cross-functional engineering, supply chain, finance, and customers; identify and mitigate technical risks; lead contract negotiations and customer-facing communications; ensure compliance with customer, internal, and regulatory requirements; hire, grow, and mentor team members in a fast-moving startup environment.
