Software Architect, Software/Firmware Device Interface Design in Lausanne

Logitech is the Sweet Spot for people who want their actions to have a positive global impact while having the flexibility to do it in their own way.

Role and Team

Logitech is defining the future of work and play through intelligent, beautifully designed peripherals.

As a Software Architect for SW/FW Device Interface Design, you sit at a critical junction in our engineering organization, responsible for end-to-end interface architecture across device and host software layers.

This role is integral to bridging product, engineering, and embedded software teams, translating business and feature needs into precise technical interface decisions, and serving as a trusted technical advisor across the organization.

Working in close partnership with Embedded Software Architects, you will define the interface design and specifications that govern how Logitech’s host software communicates with device firmware.

Those specifications flow into the device comms layer, owned and developed by the software engineering team, which downstream product teams then consume to build features and experiences across Logitech's next‑generation productivity devices.

You combine a strong software architecture foundation with fluency in C++ and a pragmatic, hands‑on mindset.

You are equally comfortable translating business and product needs into precise technical interface decisions as you are working through complex engineering trade-offs with embedded and software teams.

And you bring modern AI‑driven approaches to how you design, validate, and accelerate that work.

Your Contribution

Be Yourself.

Be Open.

Stay Hungry and Humble.

Collaborate.

Challenge.

Decide and just Do.

Share our passion for Equality and the Environment.

These are the behaviors and values you’ll need for success at Logitech.

In this role you will

• NPI and Cross‑Functional Collaboration
• Serve as the primary SW architecture liaison throughout NPI development cycles, from concept and interface definition through comms layer integration and mass production readiness.
• Work with Product Owners and UX to understand feature and experience requirements and ensure the interface design and specifications support them end to end.
• Translate product and feature needs into interface requirements that are consistent, complete, and well‑defined enough for engineering teams to build with confidence.
• Collaborate with downstream software teams to ensure the interface design and specifications meet their integration needs and scales to current and future product platforms.
• Proactively identify and resolve integration risks through early design reviews, interface walkthroughs, and collaborative prototyping.
• SW/FW Interface Co‑Design
• Partner with Embedded Software Architects to co‑design the SW/FW interface design and specifications, defining communication protocols, data models, and message semantics that govern the device/host boundary.
• Translate the co‑designed interface design into clear, documented specifications that serve as the authoritative reference for the software team's implementation of the device comms layer.
• Facilitate trade‑off discussions across embedded software, application, and platform teams to determine the right design boundaries and module responsibilities.
• Design interfaces with modularity, reuse, and testability in mind, with an eye toward future extensibility across product platforms.
• Ensure interface designs are robust and account for device diversity across Logitech's portfolio including keyboards, mice, headsets, webcams, and emerging form factors.
• Lead and personally contribute to proof‑of‑concept development to validate interface designs, de‑risk novel approaches, and accelerate team alignment.
• Device Comms Layer Architecture
• Serve as the technical authority for the device comms layer architecture, defining the patterns and design principles the development team follows when building and evolving the C++ implementation against the interface specifications.
• Conduct architecture and code reviews to ensure the comms layer faithfully realizes the interface design and specifications and presents a clean, well‑documented surface for downstream software teams to build upon.
• AI‑Driven Design & Development
• Apply AI‑assisted design methodologies to accelerate interface modeling, architectural decision‑making, and design exploration across the SW/FW boundary.
• Champion AI‑augmented development practices within the architecture and engineering organization (using internal LLM tools and possibly contributing to develop new ones).
• Key Qualifications
• Bachelor's or Master's degree in Computer Science, Electrical Engineering, Computer Engineering, or a related field.
• 5+ years of hands‑on software development and engineering experience.
• 3+ years of experience in software architecture, interface design, or systems engineering.
• Fluent in modern C++, able to architect, review, and directly contribute to C++ codebases with a strong understanding of its application in device communication and systems software.
• Proven experience developing and optimizing desktop applications for Mac and Windows platforms.
• Understanding of software‑hardware integration and familiarity with peripherals and Human Interface Devices (HID).
• Demonstrable experience applying AI‑driven tools and methodologies to software design, architecture, or development workflows.
• High analytical skills with the ability to address complex engineering challenges collaboratively across firmware, software, and product disciplines.
• Good communication (oral and writing) skills (e. g. technical documentation) and ability to synthesize information.
• Pragmatic, analytical mind, quick‑witted, meticulous, structured, organized.
• Open‑mindedness (cultural awareness) and diplomatic.
• Stress management, multitasking (multiple projects in parallel), flexibility (time zones).
• Preferred Qualifications
• Experience developing and architecting software interfaces for hardware integration in consumer electronics or peripheral devices.
• Knowledge of communication protocols such as HID, USB, and Bluetooth LE and their application in device software integration.

Education

• BS/MS in Computer Science, Computer Engineering, or equivalent education and experience.
