Key Responsibilities
- Architect: Work with the engineering manager and architects to define the multi-quarter technical roadmap for Tasker & Supply (onboarding, category eligibility, geography, matching). Drive strategy, tackle tech debt, and evolve our engine boundaries, gateway contracts, and data models.
- Tech Lead: Lead complex, cross-team initiatives around marketplace liquidity and supply-demand matching.
- Solver: Take ambiguous, high-stakes business goals and turn them into clear technical strategies, designs, and experiments.
- Operational Excellence: Improve reliability and observability (Datadog, Kafka) for onboarding, matching, and supply-side systems. Own the hard production debugging and push for real, systemic fixes.
