About the role

  • Define the Standard: Set architectural direction and establish engineering patterns that become the golden path across teams.
  • Own the Core: Design and evolve complex backend systems including multi-tenant database routing, distributed task orchestration, async pipelines, and enterprise integrations.
  • Modernize Workflows: Lead adoption of AI-assisted development practices and LLM agent systems within production environments.
  • Ship Strategic Initiatives: Take ambiguous product goals and deliver them end-to-end, from infrastructure (CDK) and deployment to monitoring and documentation.
  • Observability First: Foster a culture of observability by default, owning strategies around structured logging, APM tooling, metrics, and production debugging workflows.
  • High-Stakes Resolution: Act as a steady technical leader during production incidents, guiding root-cause analysis and long-term remediation strategies.
  • Elevate the Team: Remove technical blockers, mentor engineers, and promote psychological safety alongside a culture of continuous improvement.
  • Scale the Org: Continuously improve CI/CD pipelines, testing infrastructure, release processes, and deployment strategies so teams can ship safely at speed.

Requirements

  • Experienced Technical Leader: Typically brings 10+ years of professional software engineering experience, with flexibility for exceptional candidates who demonstrate strong Staff-level impact, ownership, and technical leadership.
  • A Technical Strategist: You have clear, experience-backed opinions on distributed systems and long-term architecture. You don’t just solve today’s problem; you design systems that support years of growth.
  • Python/Django Expert: Deep knowledge of Django internals including middleware, database routing, management commands, signals, and performance optimization in high-scale, multi-tenant environments.
  • Systems Architect: Strong experience building and evolving distributed systems across cloud infrastructure. Comfortable debugging complex concurrency challenges such as race conditions, distributed deadlocks, async failures, and large-scale database performance issues.
  • Data Fluent: Experience with dataframe-based computation tools such as Pandas, Polars, or NumPy to power data-intensive workflows and financial modeling pipelines.
  • Engineering Leader: Proven ability to define engineering standards, design reusable abstractions, and improve developer velocity through internal tooling and frameworks.
  • Efficiency Minded: Early adopter of AI-assisted engineering workflows (Cursor, Claude Code, automated refactoring, or similar tooling) to increase velocity without sacrificing reliability or code quality.
  • Effective Communicator: Able to clearly explain architectural trade-offs to executives, product partners, and engineers at all levels.
  • Nice to Have: Familiarity with FP&A domain concepts such as trial balances, charts of accounts, fiscal calendars, scenario modeling, and multi-currency workflows.
