Responsibilities
Serve as the primary technical counterpart to our external Systems Integrator. You will review and approve OpenAPI (Swagger) specifications and schema designs before implementation
Enforce the architectural separation between the Administrative State (Node.js/Postgres) and the Execution Risk State (Rithmic/TT) to ensure system resilience
Audit the code delivery pipelines (CI/CD). Ensure the agency is using proper version control (Git) and automated deployment methods, not manual updates
You are responsible for validating the system against edge cases. You will simulate failures (Example: Rithmic disconnects, latency spikes) to ensure the agency’s code recovers gracefully before we go live
Manage the AWS environment. You own the root credentials and configuration for EC2, RDS, S3, and AWS Global Accelerator
Implement best practices for DDOS mitigation (AWS WAF), IP whitelisting, and secure management of API keys/secrets
You are responsible for data integrity. You must be comfortable writing SQL queries to investigate user states, reconcile transaction logs, and generate ad-hoc reports
Monitor system health via CloudWatch, tracking API latency, error rates, and database performance
Manage the automation bus (Zapier Enterprise). You will oversee the complex logic flows that trigger user provisioning, contract generation (DocuSign), and payroll updates (Rippling)
When a webhook fails or data desyncs between Stripe and the database, you are the investigator who identifies the root cause in the JSON payload or server logs
Manage API credentials and connectivity for our institutional execution partners: Trading Technologies, Rithmic, CQG, and MetaTrader 5
Monitor system health via AWS CloudWatch (Latency, Error Rates, CPU usage)
You must be willing to act as the escalation point for critical infrastructure outages during active market sessions
Act as the lead investigator for outages, diagnosing if the issue is a database lock, a code deployment error, or a vendor failure
Partner with the founder on the technical roadmap from our current Year 1 architecture (Node.js/Zapier) toward our Year 2 goals of High-Performance Compute (HPC) and internalized engineering
Identify bottlenecks in the initial build and architect solutions for higher throughput as our user base scales to 5,000+ traders
