Fliff is seeking a Python Team Lead to lead and manage the Integration team. You will provide technical leadership for a team of at least 3 engineers while taking full ownership of backend features and improvements across the entire lifecycle—from design through implementation, deployment, and production support.
Key responsibilities include designing, developing, and maintaining scalable, high-performance backend services using Python and Django. You will build and maintain integrations with external systems including KYC providers, geolocation services, payment partners, and other third-party services. Close collaboration with product and engineering teams is essential to scope and deliver new integrations effectively.
You will implement comprehensive observability across integration flows, including monitoring, logging, and alerting to ensure system reliability. Writing unit and integration tests is a core responsibility to prevent regressions and improve overall test coverage and testing practices. You will also support production issues and participate in on-call rotations.
This role is ideal for an experienced backend engineer who thrives in early-stage startup environments and wants to grow into technical leadership. The integration focus means you'll work on critical payment and KYC flows, webhooks, callbacks, and failure-handling patterns that directly impact the business.
REQUIREMENTS:
- Experience leading and managing a team of at least 3 engineers
- At least 5+ years of development experience, with Python as the primary language
- Strong experience in API and system integrations
- Proven experience integrating third-party APIs, with deep understanding of webhooks, callbacks, idempotency, and failure handling (payments and KYC integrations are a strong plus)
- Experience with observability tools to monitor and troubleshoot production integrations
- Strong fundamentals in algorithms, data structures, and concurrency
- Experience in architecture design of highly loaded and scalable solutions
- Strong understanding of the full software development lifecycle, from requirements analysis to deployment and production monitoring
GREAT TO HAVE:
- Experience in early-stage startups and fast-paced engineering environments
- Experience writing automated tests, measuring test coverage, and defining test automation strategies
- Experience with observability tools such as Datadog, CloudWatch, or Grafana
- Experience in sports/betting industries
