About the team / Role
As an SDE 3, you will autonomously lead the design, scaling, and implementation of core backend systems and distributed data infrastructure. Balancing deep technical expertise with strong cross-functional collaboration, you will translate complex business requirements into high-performance architectures, champion engineering best practices, and actively mentor junior and mid-level engineers.
How you'll make an impact
Lead the design and implementation of complex backend features, distributed microservices, and asynchronous REST APIs optimized for high throughput, low latency, and fault tolerance.
Design event-driven data pipelines, real-time message integrations, serverless functions, and distributed caching strategies to ensure data consistency and synchronization between modern and legacy data stores.
Implement advanced error handling (retry patterns, circuit breakers), automated database migrations, and secure authentication/authorization flows (OAuth 2.0, JWT, RBAC).
Show full description
Manage cloud infrastructure via Infrastructure as Code (IaC), optimize containerized environments, and establish robust observability stacks (distributed tracing, metrics, logging).
Maintain excellent automated test coverage (unit, integration, load testing), drive performance profiling, and foster team growth through code reviews, pair programming, and technical guidance.
Experience you will bring
6+ years of professional software development experience, including 3+ years with high-level backend languages (e.g., Python, Go, Java) and 2+ years scaling production distributed systems.
Proven track record of delivering mission-critical services, featuring deep knowledge of async programming, relational databases (query optimization, partitioning), and distributed key-value caches.
Strong command of microservices communication, event streaming/message brokers, containerization, and CQRS/event-sourcing concepts.
Hands-on experience with major cloud ecosystems (serverless compute, managed storage, IAM), IaC tools, ORMs, and secure API design principles.
Exceptional analytical and communication skills, with a demonstrated ability to take absolute ownership of technical initiatives and lead alignment discussions in agile environments.
Preferred Qualifications
Experience bridging modern cloud architectures with legacy database infrastructure.
Domain background in financial services, logistics, fleet management, or dynamic pricing systems.
Experience optimizing automated CI/CD pipelines, high-availability setups, and disaster recovery planning.
Familiarity with advanced telemetry dashboards (Prometheus/Grafana) and performance profiling tools.

- Be cautious of an offer made with no real interview, or pressure to decide quickly or share financial details early.
