Developer Infrastructure - Blockchain Core

About The Role

We are looking for a passionate and experienced Blockchain Core DevInfra to join our team. A blockchain is a highly complex distributed system. Also, a blockchain has to provide absolute SLAs in terms of data correctness and availability. As such it required custom-built frameworks to bring certainty into the operations.

The blockchain dev-infra role will work closely with our PE team to ensure -

• Developer Productivity - Build efficient CI/CD, test frameworks, benchmarking, and debugging tools to enable faster iterations.
• Reliability - replicate real-world network scenarios and simulate failures. Enable stronger guarantees on the system SLAs and prevent breakage due to changes.
• Efficiency - build benchmarks and provide tooling that identifies low-level system efficiency opportunities. Enable one-click load tests to ensure consistency of throughput and latency under realistic workloads. The team at Aptos Labs is on a mission to build the highest-throughput blockchain and will require innovative frameworks to ensure the performance of the system.

What you'll be doing:

• Build and enhance the test frameworks that enable module-level testing. Isolate different components of the system and run tests that ensure individual module success (for example, consensus, networking, state-sync etc)
• Enable CI/CD pipelines that ensure all the changes are thoroughly tested and minimize the chances of regressions.
• Enable one-click load tests that can spin up 100s or nodes globally with various configurations. Simulate real-world network conditions and chaos testing.
• Build tooling to replay transactions from mainnet/ testnet to a smaller test environment.
• Build automation and visibility into the system test frameworks.

• 5+ years of experience as a software engineer
• Strong appreciation for automation and tooling.
• Experience building release or performance tooling and automation
• Experience building CI/CD pipelines
• Previous experience building/scaling infrastructure
• Nice to have: data visualization and observability tooling experience
• Be able to proactively manage prioritization of work and deliver work with great quality and influence the broader team in creating leverage
• Passion to initiate and lead projects to completion in a fast-paced, ever-changing, start-up environment
