You will join as a Senior Python Engineer to design and build a Python-based platform layer that acts as a bridge and execution environment for high-load, business-critical workflows. This is not a standalone backend but rather a strategic architectural component that decouples complexity from the core platform and enables scalable execution of business logic.
Key responsibilities include:
- Designing and building a Python-based platform layer integrated with the core system
- Defining patterns for service communication, orchestration, and responsibility split between core and Python services
- Developing scalable, async services handling high-load and latency-sensitive workflows
- Owning API contracts between systems, ensuring stability and backward compatibility
- Extracting functionality from core into scalable services to improve performance or maintainability
- Ensuring reliability through observability (monitoring, logging, tracing)
- Designing for failure with retries, idempotency, and consistency guarantees
- Driving engineering quality through testing strategy, CI/CD, and safe rollout practices
- Collaborating with Platform and Product teams to align architecture with business needs
- Contributing to long-term platform scalability
Required qualifications:
- 5+ years of commercial Python development in production environments
- Strong expertise in modern Python frameworks (FastAPI preferred; Django/Flask acceptable)
- Solid experience designing and integrating APIs, including third-party services
- Strong understanding of async programming and concurrency (AsyncIO, non-blocking I/O)
- Experience with PostgreSQL and large datasets
- Proven track record building and maintaining high-load backend systems
- Strong testing practices (unit and integration tests; PyTest preferred)
- Experience with CI/CD pipelines and Docker
- Strong ownership and product mindset
Desirable experience includes: queue systems and job processing, infrastructure work, third-party API integration, NoSQL solutions, analytical systems, and advanced database skills (replication, partitioning, sharding, PL/pgSQL).
The company offers hybrid onboarding with remote start and relocation support, comprehensive health insurance, professional development budget, flexible benefits, hybrid work arrangements, in-office perks, and company-funded team activities.
