Senior Software Engineer, Platform Infrastructure

About the role

Aptos is a people-first blockchain on a mission to help billions of people achieve universal and fair access to decentralized assets in a safe and scalable way.

Founded by some of the original creators and maintainers that researched, designed, and built the Diem blockchain to serve this purpose, we have dedicated several years toward this mission. We believe the open-source Diem technology we have developed is an important foundation of a safe and scalable web3 world where everyone has more equitable opportunities to grow and access financial assets with lower fees and fewer intermediaries.

Aptos (Ohlone for "The People") encompasses our mission and ethos for why we build.

About The Role

We're looking for a talented, driven Senior Software Engineer to build the critical infrastructure that powers the Aptos blockchain ecosystem.

This role will have significant impact and visibility - the systems you build will directly enable thousands of developers to build on Aptos. You'll work on APIs, indexers, node infrastructure, SDKs, and developer tools that form the foundation of the network. You'll help shape technical direction and may grow into leading other engineers as the team scales.

You should love solving hard distributed systems problems and have a passion for building robust, scalable infrastructure. You will be joining a lean team with a lot of autonomy – you should be a self-starter and thrive on self-directed work in a fast-paced environment.

This role sits in our Palo Alto, CA or New York, NY office.

What you'll be doing:

- Leading initiatives to design, build, and optimize backend services and platform infrastructure for the Aptos blockchain

- Developing scalable APIs, indexing services, and data pipelines to support blockchain data access

- Building and maintaining infrastructure for node operations, monitoring, and observability

- Building and maintaining SDKs, libraries, and developer tools

- Writing clean, performant, well-tested, and production-ready code

- Collaborating closely with protocol engineers, infrastructure teams, and product engineers

What you bring:

- 5+ years of experience building and shipping scalable backend systems

- Strong experience building backend systems in languages such as Rust, Go, C++, Java, Python, or similar

- Deep understanding of systems programming concepts

- Strong understanding of distributed systems, databases, and API design

- Strong problem-solving skills and the ability to work autonomously in a fast-paced environment

- Experience with blockchain infrastructure, indexing, or node operations (a plus)

- Web3 experience or familiarity (a plus)

- Background in payments, DeFi, or TradFi (a plus)

- Comfortable leveraging AI tools to enhance productivity and code quality
