About the team

We’re looking for a Sr Engineer to join our growing Regulatory Core Engineering team. We’re a key contributor to the growth of Paxos, responsible for building the services to address our customer’s regulatory, compliance and risk concerns – helping bring their financial products to market faster and easier.

About Paxos

Paxos is on a mission to enable the movement of any asset, any time, in a trustworthy way. Today’s financial infrastructure is archaic, expensive, inefficient and risky – supporting a system that leaves out more people than it lets in. So we’re rebuilding it.

As a regulated blockchain infrastructure company, we use technology to tokenize, custody, trade, and settle assets for enterprise clients like PayPal, Nubank and Interactive Brokers. Paxos is a top-funded blockchain company, with more than $500 million in total funding from leading investors like OakHC/FT, Founders Fund, PayPal Ventures, and Declaration Partners. Together, we empower today’s financial leaders to build a more open, trusted economy.

As a Sr Engineer you’ll get to:

• Design and implement high quality software from concept through to launch - taking ownership of design, coding, testing and deployment of key connectivity and messaging infrastructure.
• Apply and develop engineering best-practices including agile planning/estimation, strategic messaging patterns and best practices across the company.
• Effectively resolve ambiguity, analyzing complex requirements and breaking down features and initiatives into tactical tasks
• Effectively navigate the trade-offs among MVP vs Enterprise-Grade, Time-to-market and other relevant dimensions
• Search for the truth in product conceptualization and development, ensuring designs and implementations are fully aligned with the company mission and product goals

Your experience should include:

• 6+ years of software development experience, including at least one of the following: Golang, Kotlin, Rust, Java, C++.
• Mastery of computer science and programming fundamentals (data structures, algorithms)
• Strong previous experience in key messaging technologies like gPRC, Kafka, RMQ and ZMQ.
• Solid experience with connectivity and platform level authentication concepts, including federated authentication protocols like SAML2 and OIDC.
• Experience with API design and financial protocols like FIX and SWIFT. TCP, UDP and multicast are desirable.

You might also have:

• Design and implementation of high performance electronic trading systems including performance tuning to optimize latency, jitter, queuing and throughput.
• Solid understanding of concepts like load balancing, HA/failover, ingress, inter-service communications in a microservices style cluster, idempotence, ACID, guaranteed delivery, etc.
• Technical expert in at least one domain like Trading Systems, Distributed Systems, Cryptography, Databases, or AWS
• Can understand and articulate the architecture of an entire system, including the technical trade-offs between different design implementations of high performance, low latency order state management
• Familiar with digital-native online web application architectures and infrastructures, including clustering (Kubernetes), containerizing (Docker), telemetry/instrumentation (Prometheus/Grafana), etc.
• Eager to work openly and collaboratively with a diverse multi-disciplinary team, collaborating effectively with stakeholders
• Constantly seeks to learn new technologies, innovate and discover better ways to solve engineering challenges of high performance trading systems and APIs, including performance tuning, latency optimizations and constant new development of APIs
