Staff Software Engineer

Renesas AMS is in the middle of a strategic push to become the sensor and signal-chain vendor of choice inside the fastest-growing platforms in robotics, AI infrastructure, and automotive. That strategy lives or dies on whether we can walk into a customer’s lab, integrate our silicon onto their compute platform, and prove it works, fast, credibly, and in code the customer’s own engineers trust.

This role is the technical engine behind that proof. You will be the person who takes an inductive position sensor, an impedance-sensing IC, or a configurable mixed-signal device and makes it run on a customer’s MCU or SoC, whatever that platform happens to be. This work feeds directly into design win conversations with strategic accounts across robotics, AI infrastructure, and automotive.

What You’ll Actually Do

• Own hardware/software bring-up of AMS and sensor ICs on customer-selected compute platforms, with no assumption of a friendly Renesas reference design.
• Write driver-level firmware in C/C++ (I2C, SPI, UART, GPIO, interrupt handling, register-level configuration) directly from datasheets and schematics, often for silicon and platforms outside Renesas’s own ecosystem.
• Build application-layer demonstration code proving out specific end-use cases: optical encoder replacement via inductive position sensing, through-barrier impedance sensing, power sequencing, force/torque sensing for robotic end effectors.
• Lead technical integration for flagship joint development programs (e.g., dexterous robotic hands, industrial robotic arms) alongside strategic partners, working against hard trade-show and customer deadlines.
• Debug full signal-chain issues spanning analog front end, digital bus, and host software stack, often live, in a customer’s lab.
• Partner directly with FAEs, product marketing, business development, and customer engineering counterparts to scope PoC requirements, define technical success criteria, and hit milestones that feed directly into account strategy.
• Build reusable driver frameworks and reference architectures that scale across engagements rather than one-off, throwaway integrations.
• Represent Renesas technically in front of customer engineering leadership during lab visits and demos.
• Produce clear technical documentation (architecture, register maps, bring-up guides) usable by both internal teams and customer engineers.
• At the Staff level: provide technical mentorship to other engineers on the team and act as the escalation point for the most technically ambiguous or highest-stakes customer integrations.

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field, or equivalent hands-on experience.
• Senior: 7+ years, Staff: 10+ years, of embedded firmware/software development spanning multiple silicon vendors and MCU/SoC ecosystems.
• Strong, demonstrable C/C++ skill at both the driver and application level, not just familiarity.
• Direct experience bringing up analog/mixed-signal ICs and sensors on third-party platforms you didn’t design, from datasheet and schematic alone.
• Deep protocol-level command of I2C, SPI, UART, and Ethernet-based interfaces.
• Experience developing in both bare-metal and RTOS environments.
• Comfort operating under ambiguity: incomplete documentation, shifting customer requirements, and hard external deadlines tied to trade shows or executive commitments.
• Strong communication skills; you’ll be explaining technical tradeoffs to both engineers and non-technical stakeholders, sometimes in the same meeting.
• Willingness to travel up to 20% for customer lab visits and trade shows., * Master’s degree in a related engineering field.
• Robotics or industrial sensing background: position sensing, force/torque sensing, proximity/impedance sensing.
• Experience with edge AI compute platforms and their SDK/driver ecosystems.
• Exposure to configurable mixed-signal/state-machine-based analog design.
• Prior customer-facing technical role: FAE, solutions architect, or applications engineering.
• Python for test automation, data logging, or tooling alongside embedded C/C++.
• Experience mentoring junior or mid-level engineers.
• Experience working inside a matrixed organization with cross-functional stakeholders across sales, marketing, and engineering.
