We are hiring on behalf of our client, an elite, high-growth software development organization seeking a highly experienced Staff Platform Engineer. The employer is a major technical contributor to one of the largest and fastest-growing crypto social networks globally, with platforms generating substantial revenue and transaction volume.

This is a critical, high-leverage 0-to-1 opportunity. The successful candidate will join a team of elite builders to take the production platform from its foundational stages to global scale. There is no legacy estate to inherit; this role is responsible for making the core architectural decisions, defining how the engineering team ships code safely, and building a highly reliable, multi-region environment designed to handle immense scale and financial-grade security.

Key Responsibilities
  • Foundational Architecture: Lead the platform from zero to production and beyond, making foundational infrastructure decisions and scaling systems pragmatically as the platform grows.
  • Deployment & CI/CD Ownership: Define the deployment pipeline and ownership path from commit to safe, observable production deployment, maximizing velocity across the broader engineering team.
  • Reliability & Continuity: Design and test robust, multi-region failover and recovery systems to guarantee high availability and system continuity for high-stakes transaction processing.
  • Security & Compliance: Embed robust security, access controls, secrets management, encryption, and audit trails directly into the infrastructure foundations to meet strict regulatory standards from day one.
  • Data & Observability: Own the underlying data and event backbone required for transactional correctness, alongside the observability stack needed for rapid, real-time issue detection and resolution.
Requirements
  • Proven Engineering Depth: A hybrid background as both an expert infrastructure engineer and a strong software engineer. Competency extends beyond writing configuration and glue to reviewing and writing high-quality production application code.
  • 0-to-1 Experience: Prior experience building foundational infrastructure systems from scratch, with a clear understanding of the long-term impact of early architectural choices.
  • Production Operations: Proven track record running highly available, multi-region production systems with real-world experience managing on-call rotations, incidents, and post-mortems.
  • Risk Judgment: Exceptional ability to balance velocity with risk, knowing when to move fast and when to introduce rigorous controls.
  • Tooling Fluency: Deep familiarity with modern cloud platforms, Infrastructure as Code (IaC) frameworks, orchestrators, and data streaming systems, alongside the adaptability to master new technologies quickly.
Preferred Qualifications
  • Security Engineering: Hands-on experience with application or infrastructure security engineering.
  • Digital Assets: Familiarity with or exposure to the crypto/Web3 ecosystem and comfort operating infrastructure within this domain.
  • Technical Leadership: A history of elevating team standards through tooling, documentation, and technical mentorship.
Benefits
  • Competitive Base Salary
  • Token / Equity Allocation
Interview Process
  • Recruiter / HR Screening Call
