Semiconductor Software Engineer

• Design and build software tooling that accelerates semiconductor design and verification workflows.
• Develop firmware and low-level software interacting directly with silicon, including drivers and BSPs.
• Build infrastructure to support large-scale EDA tool execution on compute farms and cloud platforms.
• Develop post-silicon validation tooling, including high-throughput test orchestration, programmable stimulus generation, and result aggregation systems that scale across many parts and many test environments.
• Build data pipelines for design, verification, and characterization data, supporting downstream analytics and ML.
• Implement debug tooling and diagnostic infrastructure for hardware bring-up and silicon characterization, giving engineers fast feedback loops on the silicon-software interface during critical validation windows.
• Partner with hardware engineers to translate hardware-specific requirements into clean software designs.
• Optimize software for performance and scalability in compute-intensive semiconductor workflows.
• Lead architecture and code reviews that span the software-hardware boundary, ensuring that abstractions, interfaces, and constraints between the two domains are well-understood and respected across the team.
• Contribute to internal libraries and tooling shared across silicon design teams.
• Maintain comprehensive, current technical documentation - including architecture diagrams, design decisions, configuration references, runbooks, and operational procedures - so that the system remains supportable, auditable, and easy to onboard new engineers onto over time.
• Mentor and coach junior and mid-level engineers through code review, design review, pair programming, and structured knowledge sharing, helping the broader team grow in technical maturity and confidence over time.
• Continuously evaluate emerging hardware platforms and toolchains, assessing maturity, fit for purpose, and total cost of ownership, and make grounded recommendations on which to adopt, pilot, or defer based on real engineering needs., Build your best future with the Johnson Controls team!
