Staff Software Engineer - Engineer Data Platform

Mojo Vision is pioneering a highly flexible, wafers-in, wafers-out micro-LED platform to unlock AI applications in multiple market segments. Built over nine years by our skilled engineers, our system-level approach combines advanced 300mm silicon architecture with GaN-on Silicon emitters, proprietary quantum dots, photodetectors, micro-lens arrays, and packaging to solve conventional trade-offs in size, brightness, bandwidth density, and power. Our scalable, manufacturing-ready approach enables breakthrough products such as next-generation optical interconnects and AI glasses.

At Mojo, our team includes talented professionals with expertise in product design, user experience, applied physics, hardware, software, optics, photonics, electronics, chemistry, and vision science.

We are a startup founded by technology experts with decades of experience developing pioneering products and platforms backed by some of the world's leading technology investors in Cupertino, CA.

Engineering organizations generate enormous amounts of knowledge through simulations, experiments, manufacturing processes, analysis pipelines, and design decisions. Most of that knowledge remains fragmented across documents, scripts, spreadsheets, databases, and individual expertise.

We're changing that.

As our Staff Software Engineer, Engineering Data Platform, you will architect and build the foundational system that captures, connects, and preserves engineering knowledge across the company. This platform will become the digital backbone of Mojo's engineering organization, transforming isolated data into a reusable institutional asset.

• Define and own the technical architecture for Mojo's engineering knowledge and data platform.
• Design scalable systems that unify experimental, simulation, manufacturing, and analysis data.
• Create data models that represent complex engineering workflows, relationships, provenance, and metadata.

• Develop services, APIs, ingestion pipelines, and core platform capabilities.
• Integrate data from laboratory equipment, simulations, manufacturing systems, and engineering tools.
• Establish data quality, lineage, observability, governance, and security.

• Partner closely with engineers and domain experts across multiple disciplines.
• Simplify workflows while standardizing how engineering information is captured and shared.
• Build systems that engineers genuinely want to use because they make work easier, faster, and more effective.

• Help define how AI systems interact with engineering knowledge and design data.
• Contribute to the evolution of Mojo Studio, our AI-assisted co-design simulation platform.
• Influence company-wide technology strategy through hands-on technical leadership.

• BS, MS, or PhD in Electrical Engineering, Optical Engineering, Physics, Mechanical Engineering, Computer Engineering, or a related field.
• 8+ years building production-grade software platforms, backend systems, or data-intensive applications.
• Demonstrated success leading architecture and implementation of large-scale technical systems.
• Strong experience designing and operating cloud-native systems on AWS.
• Deep understanding of APIs, relational data models, object storage, queues, event-driven systems, and data-processing pipelines.
• Experience designing data-modeling skills, including metadata, identifiers, schema evolution, lineage, and complex relationships.
• Expertise with infrastructure-as-code, containers, CI/CD, monitoring, and production operations.
• Strong understanding of data quality, validation, observability, security, reproducibility, and failure handling.
• Ability to work effectively in ambiguous environments and translate complex engineering needs into practical software.

• Masters or PhD in Computer Sciences preferred
• Scientific computing or engineering software
• Semiconductor, EDA, photonics, or advanced manufacturing systems
• AWS services such as S3, RDS, ECS/EKS, Lambda, SQS, and IAM
• Workflow orchestration and distributed processing
• Knowledge graphs, provenance, or lineage-based systems
• AI infrastructure, MLOps, or agent-facing data platforms
• Authentication, authorization, and data-governance systems

This is a rare opportunity to serve as the technical leader for a strategic platform initiative. You will define the architecture, establish engineering standards, and help create the data foundation that enables AI-assisted engineering and future intelligent design systems.

If you're excited by complex technical challenges, ambiguity, and the chance to build something foundational from the ground up, we'd love to talk with you.
