Systems programming in C, C++, and Rust;
Low-level performance optimization and hardware interfacing;
Distributed systems and threading runtimes;
CI/CD pipeline design using GitHub Actions and on-prem infrastructure;
Work with multiple systems, including web development platforms, high-performance computing systems, core operating system kernels, developer tools, and systems related to economic applications;
Develop distributed ledger technologies or crypto economic distributed systems.

Responsibilities

Design and implement system-level components for blockchain infrastructure using C, C++, and Rust.
Maintain strong emphasis on computer systems analysis and implementation.
Gather requirements for high-throughput, low-latency (≤ 200 ms p95) services; design distributed systems that meet 99.9 % availability SLAs.
Perform benchmarking and performance profiling to enhance execution efficiency.
Specify, version, and maintain public and internal APIs plus JSON-RPC/gRPC endpoints.
Document interfaces and generate strongly typed client libraries.
Collaborate on the development of secure, low-latency networking protocols and cryptographic primitives.
Build fault-tolerant ETL pipelines that transform on-chain events into query optimized relational & NoSQL stores.
Tune indexes for millisecond reads.
Provision and scale commodity server fleets (on-prem & cloud).
Automate with Terraform/Kubernetes, monitor health, capacity, and SLOs.
Migrate legacy computing pipelines to modern CI/CD frameworks.
Support the design of fault-tolerant systems with advanced debugging, logging, and error recovery functionality.
Model token-economic incentives, auction fee markets, and validator/operator behaviors; prototype algorithms and run agent-based simulations.
Leverage generative-AI coding agents, static analyzers, and self-healing runbooks to accelerate delivery and cut MTTR.
Review performance metrics to refine software components for memory and process or efficiency.
Profile CPU, I/O, and network paths; execute load-tests; instrument metrics/tracing/logs; drive post-mortems and capacity plans.
Maintain and manage a performant suite of APIs, SDKs, and developer tools for consumption by external developers.
Integrate cryptographic primitives, secure key management, vulnerability scanning, and incident response playbooks.
Write RFCs, lead design reviews, mentor junior engineers, and coordinate cross-functional delivery with product, infra, and legal teams.
100% telecommuting/working from home permitted from various and unanticipated locations throughout the U.S.
