We are hiring a Principal Software Engineer for Arm's AI Platforms team in Bangalore. You will help shape technical direction, build production software, and establish the engineering practices of a growing team. Working with the Director of Engineering and technical leaders across Arm, you will take responsibility for significant platform capabilities and remain closely involved in their implementation.

We are looking for an exemplary practitioner whose code, technical decisions, and approach to difficult problems set the standard for the team. You will combine systems engineering depth with hands-on expertise in agentic AI across the software development lifecycle (SDLC), helping engineers embrace new methods and assess their effect on delivery and quality.

Responsibilities

• Define technical direction with engineering leadership. Assess platform needs, explore design options, and turn decisions into software the team can deliver and operate.
• Design and implement distributed platform services. Write critical code, review implementations, and rapid prototyping to test uncertain assumptions before committing to a design.
• Shape the engineering culture through daily practice. Help the team deliver frequent changes with clear ownership, useful design and code reviews, and verification appropriate to the software being built.
• Build and use agentic AI workflows across the SDLC. Give agents useful project context, connect them to development tools, and establish feedback through tests and code review. Measure their effect on delivery speed and software quality.
• Keep current with developments in software engineering, AI development tools, and cloud systems. Evaluate promising approaches through hands-on experiments and adopt them when the results justify the change.
• Resolve difficult design and production problems involving concurrency, data consistency, performance, and failure recovery. Use what you learn to improve the architecture and the team's engineering practices.
• Help recruit staff and senior engineers, and develop their judgment through shared technical work. Support engineers in taking ownership of complete capabilities and working through unfamiliar problems.
• Partner with Arm teams in the US and UK on architecture and shared interfaces. Make technical decisions understandable and establish clear ownership across teams.

Required skills and experience

• 12+ years building distributed software, cloud platforms, or production infrastructure, or equivalent experience demonstrated through the scope and impact of your work.
• Strong programming skills in Go, C++, Rust, Python, or a comparable language. Experience designing service interfaces, working with concurrency and persistent data, and debugging complex failures.
• Experience building and operating software on Kubernetes and Linux, with an understanding of workload lifecycle, networking, resource management, and failure recovery.
• Hands-on expertise with agentic AI tools and harnesses for the SDLC. Experience configuring and extending workflows, assessing generated code, and verifying changes through automated checks and engineering review.
• A record of technical leadership grounded in your own engineering work, including mentoring experienced engineers, explaining design choices, and improving how a team develops software.

Preferred skills and experience

• Experience with AI inference infrastructure or model serving, including how workload and hardware choices affect latency, throughput, and resource use. Knowledge of inference performance and resource-efficiency considerations.
• Familiarity with frameworks such as PyTorch, Ray, vLLM, SGLang, TensorRT-LLM, or Dynamo or experience qualifying accelerators and tuning distributed workloads.
• Kubernetes controllers or operators, deployment systems, or software that manages releases across different compute environments.
• Developer productivity tools, build and test infrastructure for large scale distributed systems.
• Distributed tracing, observability, diagnostics, or data processing systems used to understand production behavior.

Use of AI in Your Application

At Arm, we embrace the benefits AI can bring, including in recruitment. You may use AI to support your preparation, such as improving the clarity of written responses, practicing interview questions, or learning more about our industry. However, your application and interview responses must reflect your own thinking, experience, and abilities. We want to understand your authentic perspective, creativity, and approach to problem solving. As such, you may not use AI to complete assigned tasks as part of any assessments. If you plan to use AI-supported or assistive technologies as part of a reasonable adjustment, please contact accommodations@arm.com so we can support you.

Recruitment Adjustments and Accommodations

At Arm, we want to build extraordinary teams. If you need an adjustment or an accommodation during the recruitment process, please email accommodations@arm.com. To note, by sending us the requested information, you consent to its use by Arm to arrange for appropriate accommodations. All accommodation or adjustment requests will be treated with confidentiality, and information concerning these requests will only be disclosed as necessary to provide the accommodation. Although this is not an exhaustive list, examples of support include breaks between interviews, having documents read aloud, or office accessibility. Please email us about anything we can do to accommodate you during the recruitment process.

Hybrid Working

Arm’s approach to hybrid working is designed to create a working environment that supports both high performance and personal wellbeing. We believe in bringing people together face to face to enable us to work at pace, whilst recognizing 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, and where this is the case, we will collaborate with you to find the best solution. Please talk to us to find out more about what this could look like for you.
