• 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.

• Provide deep technical leadership across multiple teams. • Drive the design and execution of complex, cross-cutting engineering initiatives. • Shape architecture and help deliver ambitious technical roadmaps. • Collaborate with cross-functional partners — product, design, engineering, operations, and business stakeholders. • Raise the bar through code review, design review, and mentorship of junior engineers. • Lead the design and execution of large, complex engineering initiatives. • Develop architectural standards and reference patterns. • Contribute hands-on code where most leveraged.

• Lead enterprise-wide architectural initiatives • Define long-term technology strategy • Deliver highly scalable, resilient distributed systems • Drive strategic engineering decisions and serve as a technical authority across multiple teams • Guide engineering teams on concurrency, scalability, observability, and optimization strategies • Mentor Staff and Senior Engineers

Role Description This is not a standard Senior SDE role. We are looking for mobile product builders: engineers who can take a problem from an ambiguous idea to a shipped, instrumented, and continually improving mobile experience product. In this role, you will help define the problem, shape the solution with product and design partners, build across the iOS, Android and supporting services when needed, ship with strong operational discipline, measure what happened, and improve it over time. We’re looking for engineers who combine strong technical judgment with product sense, business context, and a modern AI-native way of working. You Will Get To: - Turn ambiguous product ideas into clear plans, tradeoffs, success measures, and shippable solutions. - Shape mobile experiences across iOS and Android with strong product and platform judgment. - Partner closely with product, design, data, and engineering peers to refine requirements and improve the customer experience. - Build primarily in native mobile codebases while contributing to backend or API layers when needed to deliver the full experience. - Launch features with an appropriate approach to testing, rollout, monitoring, and risk management. - Follow features into production, evaluate performance and customer behavior, and iterate based on what you learn. - Strengthen the team through code review, design feedback, mentoring, and high engineering standards. Qualifications - Significant experience building and shipping production mobile applications on iOS or Android, with strong depth in one platform and the ability or willingness to contribute to the other. - Track record of owning features end to end, from ambiguous problem definition through launch and post-launch iteration. - Strong product and business judgment and ability to connect technical decisions to customer impact. - Practical experience using AI-assisted development tools or automation in day-to-day work, while maintaining accountability for quality, correctness, and customer experience. - Effective collaboration with cross-functional partners, including product managers, designers, data partners, and other engineers. - Comfortable working across the stack when needed, including mobile clients, APIs, services, and data-informed decision-making. - Strong operational discipline, including experience with production support, monitoring, debugging, and using signals to guide improvements. Requirements - This role has been categorized as a Remote position. “Remote” employees do not have a permanent corporate office workplace and, instead, work from a physical location of their choice, which must be identified to the Company. - U.S. employees may live in any of the 50 United States, with limited exceptions. - In California, Connecticut, Maryland, Massachusetts, New Jersey, New York, Washington state, and Washington DC the standard base pay range for this role is $160,900.00 - $257,100.00 annually. - In Colorado, Hawaii, Illinois, Minnesota, Nevada, Ohio, Rhode Island, and Vermont the standard base pay range for this role is $152,900.00 - $244,300.00 annually. - In addition to a competitive base salary, this position is also eligible for equity awards based on factors such as experience, performance, and location. Benefits - Employees in this role will not be paid below the salary threshold for exempt employees in the state where they reside.
