The

Toronto Neuron team at Amazon's Annapurna Labs

is looking for driven engineering students ready to do serious work on

custom silicon and machine learning systems . This isn't a fetch-coffee internship - you'll be embedded in a team that designs the chips and software powering AWS at global scale, working on

ML Systems Software Development

from day one in

Toronto, Ontario . Depending on your background and interests, you'll be placed on either the

Frontier Model Performance team

or the

Developer Experience (DevEx) team . Both focus on

AWS Trainium

- Amazon's custom machine learning silicon - and both involve real engineering problems with real customer impact. About the Role: ML Systems Software Development Engineer Intern

On the

Frontier Model Performance team , you'll take newly released machine learning models from first bring-up to

peak performance on AWS Trainium silicon . That could mean writing and tuning kernels, optimizing sharding and model execution, building benchmark infrastructure, or tackling architectural bottlenecks that shape future chip designs. The best ideas get turned into reusable

Neuron components

and optimization techniques that flow into flagship open-source and customer workloads. On the

DevEx team , you'll build the tools that make Trainium performance visible - owning Neuron Explorer and developing profiling, debugging, and analysis capabilities so engineers can identify bottlenecks and optimize faster. That could mean low-level

performance data collection , analysis engines, interactive visualizations, or developer workflows. In either team, you'll work alongside experienced

machine learning and systems engineers

who are invested in your growth. You'll collaborate across disciplines, take ownership of real deliverables, and contribute to software that runs at massive scale.

Safety, code quality, and clear technical communication

are valued throughout the team. Perks and Salary





This

internship position in Toronto, ON

offers a starting salary of

$100,810 CAD annually . Amazon also provides

basic life and AD&D; insurance ,

paid time off , and access to other resources aimed at improving health and well-being. Internship terms are versatile, with options for a

12-16 month placement starting May 2027

Your day-to-day will vary depending on which team you join, but the common thread is solving hard engineering problems at the intersection of

machine learning and custom hardware . You'll own meaningful workstreams, produce results that matter to real customers, and learn from engineers who've built some of the most sophisticated ML infrastructure on the planet. Bring up and optimize

state-of-the-art machine learning models for peak performance on

AWS Trainium silicon Write and tune kernels , optimize model sharding and execution, and tackle architectural bottlenecks that influence future hardware designs Build benchmark and measurement infrastructure

to evaluate model performance across hardware generations Develop reusable Neuron components

and optimization techniques applicable to flagship open-source and customer workloads Build profiling, debugging, and analysis tools





within the Neuron Explorer ecosystem to surface performance data for engineers Design and implement

low-level performance data collection pipelines, analysis engines, and interactive visualizations Collaborate with ML and systems engineers

to identify and resolve performance bottlenecks across model and kernel execution Requirements / Skills

Amazon is looking for engineering students who are genuinely curious about

machine learning systems, compilers, or hardware-software co-design . You don't need to be an expert in everything - but you should have solid fundamentals, hands-on coding experience, and a demonstrated interest in at least two of the technical domains listed below. Current enrolment
