What you will do

• Embed with client teams to advise and architect scalable infrastructure solutions for high-growth crypto and FinTech applications, leading strategy discussions and managing project timelines for complex system migrations and scaling initiatives.
• Design and implement robust data pipelines, real-time streaming architectures, and distributed systems that handle demanding workloads across web3 applications and protocols.
• Build and optimize cloud infrastructure with comprehensive observability solutions to ensure system reliability, performance, and rapid incident response.
• Architect solutions that bridge traditional FinTech infrastructure with web3 systems - handling blockchain node management, indexing pipelines, high-frequency data feeds, and unique crypto-native requirements.
• Uplevel client engineering teams through mentorship, improved DevOps practices, enhanced platform reliability, and help grow our team's capabilities by experimenting with cutting-edge infrastructure tools.

Requirements

• 5-7+ years of infrastructure engineering experience with proven expertise building and operating systems at scale: data stores (PostgreSQL, Redis, DynamoDB), data pipelines, cloud infrastructure (AWS, GCP, Azure), DevOps tooling, and IaC (Terraform, Pulumi, CloudFormation).
• Track record working with high-volume, mission-critical systems such as websocket feeds, real-time data flows, payment rails, or distributed architectures handling millions of transactions.
• Actively uses AI tooling to inform architecture decisions, enhance observability, and accelerate debugging workflows; strong experience with monitoring stacks (Datadog, Grafana, Prometheus, ELK), containerization (Docker, Kubernetes), and modern CI/CD pipelines.
• Proven consulting/contracting experience with strong client management skills and excellent communication abilities for explaining technical tradeoffs and infrastructure decisions to both technical and non-technical stakeholders.
• FinTech experience strongly preferred; crypto/web3 experience is a plus but not required.
• Self-sufficient professional who thrives with autonomy while managing client expectations and project timelines.

Nice to have

• Experience running blockchain nodes (Ethereum, Solana, or other chains), managing blockchain data infrastructure, or working with indexing solutions (The Graph, custom indexers, RPC infrastructure).
• Background with payment processing systems, ledger architecture, financial transaction systems, or security and compliance requirements in regulated environments.
• Experience with event-driven architectures and message queues (Kafka, RabbitMQ, SQS).
• Knowledge of database optimization for high-write workloads and time-series data.
• Relevant industry certifications (AWS Certified Solutions Architect, CKA, etc.) or technical publications.
