Software Development Engineer , Annapurna Labs

Annapurna Labs, an Amazon company, is at the forefront of cloud infrastructure innovation. Our team designs custom silicon that powers the world's largest cloud — from Graviton processors and Nitro security chips to Trainium and Inferentia machine learning accelerators.

We are a multidisciplinary engineering organization where hardware meets software at a massive scale. Our chips and systems run millions of workloads across AWS, and our low-level software is the critical layer that brings this silicon to life. Joining Annapurna Labs means working on technology that shapes the future of cloud computing.

• Key job responsibilities
• We are looking for talented Software Development Engineers to join our teams in Tel Aviv or Haifa and work on low-level software development. You will be building the foundational software layers that sit closest to the hardware — enabling high performance, reliability, and efficiency for AWS services at an unprecedented scale.

This is an opportunity to work in a deeply technical environment where your code runs on custom-designed silicon, directly impacting the performance and cost of cloud infrastructure used by millions of customers worldwide.

Design, develop, and optimize low-level software including device drivers, firmware, and hardware abstraction layers

Collaborate closely with hardware design teams to define hardware-software interfaces and bring-up new silicon

Write performance-critical systems software in C/C++ that operates under strict latency and resource constraints

Debug complex hardware-software interactions

Contribute to system architecture decisions and define software design patterns for next-gen chip features

Develop and maintain automated test frameworks to validate functionality and performance at scale

Participate in code reviews and drive engineering best practices within the team

• A day in the life
• Your Path to Embedded

This role is also an excellent opportunity for experienced software engineers looking to transition into embedded and low-level development. If you come from a general software engineering background — backend services, distributed systems, cloud applications — and are curious about what happens beneath the abstractions, this is your chance to make the move.

We invest in engineers who are eager to learn. You will receive:

Structured onboarding with a dedicated mentor from the hardware-software boundary team

Hands-on ramp-up: start with well-defined driver modules and gradually expand to architecture-level contributions

Pairing with experienced embedded engineers

What matters most is strong C/C++ skills, a debugging mindset, and genuine curiosity about how systems work at the lowest level. You don't need to know everything on day one — we'll help you get there.

Basic qualifications

• - 5+ years of non-internship professional software development experience
• - 2+ years of non-internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• - Experience programming with at least one software programming language
• - Bachelor's degree in Computer Science, Engineering, Mathematics, or a related field

Preferred qualifications

• - Experience building complex software systems that have been successfully delivered to customers
• - Experience contributing to the architecture and design (architecture, design patterns, reliability and scaling) of new and current systems
• - Experience in embedded development in C/C++
