Cyberbacker Careers; Cebu City; On-site; PHP 1,800,000 - 2,400,000; Full time

Job summary

Cyberbacker Careers seeks a senior software leader to architect and operate a large, multi-tenant SaaS platform. You will own production releases, drive platform hardening, and guide AI-assisted coding with strict quality controls.

You have 8+ years building production software, strong TypeScript/Next.js/Python stack, and proven ability to manage tenant isolation, security, and cost controls. This role requires hands-on production experience and a clear technical roadmap.

Qualifications

• Eight or more years building production software and leading senior, staff, or principal-level responsibility.
• Personally shipped and operated a multi-tenant B2B SaaS product.
• Strong experience with TypeScript, Next.js, Python, FastAPI, Postgres, SQL, and row-level security.
• Proven judgement in multi-tenant architecture, tenant isolation, secrets management, least privilege, security, and auditability.
• Deep experience with durable queues, 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.

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.
