Integration/API architect

Job Description

Job Title: Senior Integration/API Architect. Location: Palo Alto, California, USA

Responsibilities:

• Design and scale the integration architecture connecting photonic IC (PIC), passive IC, and active IC design toolchains.
• Develop and deploy software for test systems, product platforms, and manufacturing data management.
• Design and standardize APIs to enable interoperability between EDA tools, in-house photonic solvers, PDK infrastructure, and CI/CD systems.
• Build and maintain middleware and adapters for commercial and proprietary engineering tools with inconsistent or limited APIs.
• Define and implement API versioning, schema validation, and backward compatibility strategies;
• Develop observability and traceability solutions, including logging, metrics, and data lineage tracking to ensure reproducibility and auditability.
• Collaborate with device, layout, and simulation engineers to translate engineering requirements into scalable software platforms.
• Design canonical data models that preserve design intent and traceability from schematic through layout, verification, extraction, and tape-out.
• Support automation, reproducibility, and secure integration across photonic IC design workflows.
• Work closely with cross-functional software and hardware engineering teams in a fast-paced startup environment.

Qualifications:

• Bachelor's or Master's degree in Computer Science, Electrical Engineering, Physics, or a related technical field.
• At least 7 years of software engineering experience with significant exposure to systems integration or platform architecture.
• Proven experience designing and managing APIs using REST, gRPC, and event-driven architectures.
• Experience with data interchange formats such as Protocol Buffers, Avro, or similar technologies.
• Experience integrating with enterprise data platforms such as Databricks, Tableau, or similar.
• Strong programming skills in Python;
• Proficiency in at least one backend or systems programming language such as Go, C++, Java, Rust, or similar.
• Experience integrating proprietary and commercial engineering tools with inconsistent APIs.
• Experience defining canonical data models and managing schema evolution and versioning.
• Familiarity with CI/CD systems, Docker, Kubernetes, or equivalent orchestration platforms.
• Experience implementing logging, monitoring, and observability for distributed systems;
• Strong understanding of software architecture principles including scalability, modularity, loose coupling, and reliability.
• Experience working in engineering-intensive domains such as EDA, semiconductor design, hardware engineering, or scientific computing.
• Excellent written and verbal communication skills.
• Strong analytical, problem-solving, and organizational skills.
• Ability to lead multiple priorities while working independently and collaboratively.
• Demonstrated interest in quantum computing.

Preferred:

• Experience working with photonic IC design environments.
• Experience with semiconductor or EDA toolchains.
• Familiarity with GitLab-based CI/CD workflows;
• Experience with optical modeling, electromagnetic simulation, process modeling, or packaging co-design.
• Experience supporting silicon validation workflows.

Benefits and Compensation:

• Base salary:
  • U.S. Range: $165,000 to $185,000 per year.
  • Bay Area Range: $180,000 to $200,000 per year.
