We are building mission-critical infrastructure at the intersection of digital assets, fintech, and AI-native engineering.
This is not a typical senior engineering role.
You will own the core architecture and implementation, set the bar for engineering excellence, and solve the most complex technical challenges in a highly secure, regulated environment.
If you thrive on deep technical problems, ultra-high scale, and hands-on coding, this role is designed for you.
What you will be doing:
- Personally design, code, and optimize high-throughput backend systems running 24/7
- Write production code powering: Trading pipelines / Clearing & settlement systems / Funding infrastructure / Custody workflows
- Ensure systems operate at 100k+ TPS with ultra-low latency
- Debug low-level performance bottlenecks and latency issues
- Optimize memory usage, garbage collection, and concurrency behavior
- Guarantee data consistency across distributed systems
- Define technical specifications for: Microservices architectures / Event-driven systems / API standards
- Produce detailed design documentation that engineering teams build against
- Set the standard for code quality and engineering rigor
- Lead deep technical code reviews
- Establish CI/CD patterns and best practices
- Mentor senior engineers technically (not people management)
- Design for fault tolerance and observability
- Work hands-on with: Kafka-based event pipelines / Kubernetes infrastructure
- Ensure mission-critical uptime and system reliability
- Actively leverage AI tools for engineering acceleration: LLM-assisted coding / Automated test generation / Intelligent debugging workflows
- Help define what future-ready AI engineering looks like
What you will bring:
- 10+ years of software engineering experience
- Strong track record of staying hands-on in production code
- Expert-level proficiency in: Scala/Java/Go
- You should be comfortable discussing: Memory management / Concurrency models / JVM tuning
- Strong understanding of: CAP theorem & consistency models / Event streaming architectures / Cloud-native infrastructure on: AWS / Microsoft Azure / Google Cloud
Environment Experience
- Experience building secure systems in:
- FinTech
- Crypto / Digital Assets
- HealthTech
- Defense or similar regulated sectors
AI Engineering Tools
- Hands-on daily usage of: Copilot / Cursor
- Similar AI-assisted development tools
Nice to have:
- Blockchain integrations or custody/wallet infrastructure experience
- Matching engines, risk engines, or high-frequency trading systems
- Contributions to open-source infrastructure projects
