Build to Protect Civilization

TRM is a blockchain intelligence company that’s on a mission to build a safer world for billions of people. We’re a lean, high-impact team tackling some of the world’s most critical challenges, ranging from human trafficking and financial fraud to terrorist financing. We are builders who power governments, financial institutions, and crypto companies when the clock is running and the consequences are real. This is why every TRMer is a bet on our future and has the power to change our trajectory.

We’re looking for a Senior Software Engineer to join our Blockchain Protocol team — a group that builds systems to analyze and instrument blockchain peer-to-peer (P2P) networks. The systems you build will surface hidden insights about how blockchain nodes communicate, propagate transactions, and behave under real-world network conditions.

You’ll work across network protocols, distributed systems, and large-scale data ingestion, designing software that collects, analyzes, and transforms node-level data into actionable intelligence.

The impact you’ll have here:

• Operate and scale blockchain nodes across multiple chains (Bitcoin, Ethereum, Tron, BSC) to enable deep network visibility
• Research and instrument blockchain and network protocols to extract proprietary telemetry data.
• Build and maintain distributed data-collection systems and ingestion pipelines (Python, Airflow, GCP).
• Design and optimize message propagation, peer discovery, and re-org detection pipelines.
• Collaborate with researchers and data engineers to turn raw network data into high-impact intelligence for TRM’s products.

What we’re looking for:

• Proven experience in distributed systems, data ingestion, or protocol engineering.
• Strong programming skills in Python and at least one systems language (Rust, C++, or Go).
• Experience working with network protocols (TCP/IP, libp2p, gRPC, RPCs) or operating large-scale data systems.
• Familiarity with cloud infrastructure and orchestration tools (GCP, Kubernetes, Terraform, Airflow).
• Understanding of network-level behaviors such as message propagation or synchronization.
• Excellent verbal and written communication skills; clear documentation and succinct communication are very important.
• Ability to work independently, be proactive, prioritize, communicate, and set and meet goals
• Flexibility to coordinate across global time zones and an ability to work independently with minimal oversight
• A passion for solving complex network and protocol challenges at scale, and building systems that are robust, performant, and secure

Bonus Points:

• Experience running or instrumenting blockchain nodes (Bitcoin, Ethereum, etc.).
• Prior work with network observability or telemetry systems (Kafka, Arrow, gRPC).
• Contributions to open-source networking or blockchain infrastructure projects.

Why TRM Labs:

You’ll sit at the intersection of research, data, and engineering — designing systems that extract insights no public API exposes. Our team operates blockchain nodes at scale, instruments network behavior, and partners with data scientists to turn raw network telemetry into intelligence that helps build a safer financial system.
