Senior Software Engineer

The engineering team at Chainalysis is inspired by solving the hardest technical challenges and creating products that build trust in cryptocurrencies. We’re a global organization with teams in Denmark, UK, Canada, the USA, and Israel who thrive on the challenging work we do and doing it with other exceptionally talented teammates. Our industry changes every day and our job is to create user facing products supported by a flexible and scalable data platform allowing us to adapt to those rapid changes and bring value to our customers.

We're currently looking for a Senior Software Engineer to join our Hexagate team.

Hexagate builds cybersecurity products that protect on-chain and web3 assets. We sit at the intersection of cybersecurity and blockchains—an adversarial space where attacks are constant and response time matters. We’re building a real-time on-chain detection and response platform that combines ML-driven threat intelligence, custom detections, and an LLM-powered rules engine to protect on-chain assets.

What you'll build:

• Real-time pipelines: ingest, normalize, enrich, and route multi-chain activity at high throughput.

• Detection engines: Our internal monitoring language (DSL), statistical/anomaly models, ML models, and threat intelligence

• Response workflows: turn detections into alerts, automations, and integrations (webhooks/SIEM).

• LLM systems: help users translate intent into monitors/workflows and speed up investigations—safely and predictably.

• Production ownership: design → build → deploy → operate. Improve observability, latency, and reliability.

We’re looking for candidates who have:

• Senior backend experience. You’ve shipped and operated production services.

• Distributed systems experience: reliability, latency, concurrency, backpressure, and idempotency.

• Strong API design and data modeling skills (relational + event-driven).

• High ownership. You drive work end-to-end and care about outcomes.

• Strong collaboration. You communicate clearly and raise the quality bar.

You might also have:

• Web3/blockchain experience/ interest..

• Real-time / streaming data experience.

• Security or fraud domain experience.

Technologies we use:

• Languages: Python, Rust, Go

• Infra: Kubernetes, AWS, Grafana, Pulumi

• Streaming & Messaging: NATS

• Data stores: PostgreSQL, Redis, S3
