Principal Implementation Engineer

Staff / Principal Implementation Engineer

Join to apply for the Staff / Principal Implementation Engineer role at Arm
.

We are bringing together phenomenal talent and expertise from across the semiconductor industry to drive how the next generation of leading AI compute on Arm devices are built. We are rapidly growing the Systems IP team to develop best‑in‑class solutions based on Arm's IP, addressing AI challenges in secure compute, large screen compute, infrastructure and automotive markets. As an implementation engineer, you'll influence Arm solutions development to optimize power and performance, innovate, evolve and deploy optimal tape‑out quality implementations.

• Physical implementation of Arm solutions using the full physical implementation flow from RTL to GDSII, including synthesis, floor planning, place & route, static timing analysis, power analysis and physical verification.
• Optimize performance, power and area as needed and build outstanding implementations of our designs.
• Work collaboratively with design teams, influencing system micro‑architecture to achieve the highest standards.
• Enable our chip‑design partners to support their physical implementation success.

• Large SoC systems integration
• Power and physical architecture
• Design for test
• Good understanding of synthesis, place & route, clock‑tree synthesis, constraint development, timing closure and knowledge of hardware languages – Verilog/System Verilog.
• Writing and validating UPF
• Experience with tools such as Genus & Innovus, Conformal low‑power, Primetime/Tempus and other relevant physical implementation tools.
• Algorithmic thinking with some programming experience in Tcl, Make and Linux shell.
• Ability to analyze problems, reason logically about solutions and chart an appropriate course of action.
• Curiosity about embracing new silicon implementation techniques and methodologies.
• Teamwork with good communication, able to present ideas, results and conclusions professionally and organized.

• Knowledge of systems architecture, Arm IP and Arm‑based SoCs.
• Interest in AI hardware technology.
• Past experience with programming languages for data processing and presentation.
• Experience with low‑power design techniques – clock and power gating, voltage/frequency scaling, retention.
• Understanding of power delivery and experience with static and dynamic IR‑drop analysis.
• A STEM degree in a relevant field such as electronics engineering or computer science.

You will use your engineering skills to build support for the technologies and influence millions of devices for years to come. You will be able to drive and bring your ideas to a wider group of leading experts, build your technical leadership and influencing skills, and build towards becoming an established and recognised expert within the team.

Our 10x mindset guides how we engineer, collaborate and grow. Understand what it means and how to reflect 10x in your work:

At Arm, we want to build extraordinary teams. If you need an adjustment or an accommodation during the recruitment process, please email  By sending us the requested information, you consent to its use by Arm to arrange appropriate accommodations. All accommodation or adjustment requests will be treated confidentially, and information concerning these requests will be disclosed only as necessary to provide the accommodation.

Examples of support include breaks between interviews, having documents read aloud, or office accessibility.

Arm’s approach to hybrid working is designed to create a working environment that supports both high performance and personal wellbeing. We bring people together face to face to enable us to work at pace, whilst recognising the value of flexibility. Within that framework, we empower groups/teams to determine their own hybrid working patterns, depending on the work and the team’s needs.

Details of what this means for each role will be shared upon application. In some cases, the flexibility we can offer is limited by local legal, regulatory, tax or other considerations; where this is the case,…
