Job description

Mission

Turn 10xSearch from a large AI-built platform into a coherent, secure, economical white-label product that can be operated reliably and scaled through measured fleet trials.

Key Responsibilities

• Establish the canonical production architecture, repository, data model, and release path.
• Freeze and harden the three highest-value end-to-end client workflows.
• Close gaps in tenant isolation, integrations, testing, recovery, security, and capacity.
• Consolidate or retire duplicate queues, surfaces, scripts, and pipelines.
• Own production releases, canaries, rollbacks, migrations, incident response, and disaster recovery.
• Enforce provider quotas, cost budgets, idempotency, backpressure, and operational telemetry.
• Direct AI coding agents through bounded tickets and rigorously review their output.
• Translate product and content requirements into executable acceptance contracts.
• Produce an evidence-backed assessment of 1,000-client capacity and unit economics.
• Create a technical roadmap that clearly separates platform hardening from new feature development.

Required Qualifications

• Eight or more years building production software, including senior, staff, or principal-level responsibility.
• Personally shipped and operated a multi-tenant B2B SaaS product.
• Strong TypeScript, Next.js, Python, FastAPI, Postgres, SQL, and row-level security experience.
• Proven judgment in multi-tenant architecture, tenant isolation, secrets management, least privilege, security, and auditability.
• Deep experience with durable queues, leases, retries, idempotency, dead-letter handling, backpressure, and ambiguous-write recovery.
• Experience managing external-provider quotas, throttling, failures, and cost controls.
• Disciplined ownership of database migrations, production observability, incident response, rollback, and disaster recovery.
• Hands-on experience with load, soak, integration, and end-to-end testing.
• Effective use of AI coding agents without lowering engineering or review standards.
• A demonstrated willingness to simplify inherited systems and remove unnecessary duplication.
• This person must have personally operated production systems, not merely built features that someone else operated.

Technical Requirements

• Intel Core i3 (6th to 12th gen), i5, i7 or AMD equivalent is highly required
• Windows 10 or MAC OS is acceptable
• RAM: At least 8GB RAM with 60GB free hard disk space available
• Headset with a noise-canceling feature
• High Definition Webcam
