Hands-On Backend Development

• Write high-quality, maintainable, production-ready code.
• Integrate with external APIs (marketing platforms, cloud services, internal microservices).
• Build and maintain CI/CD pipelines and infrastructure-as-code environments.
• Lead code reviews, mentor engineers, and ensure high engineering standards.
• Contribute to platform SDKs, internal libraries, and backend frameworks used across the platform.

Performance, Reliability & Observability

• Implement tracing, structured logging, metrics, dashboards, and alerting.
• Optimize services for latency, concurrency, throughput, and cost efficiency.
• Ensure system reliability through automated testing, load testing, error budgets, and resiliency strategies.
• Partner with SRE to define SLIs/SLOs and improve platform-wide reliability.

Cross-Functional Collaboration

• Work closely with product, data, and SRE teams on shared backend designs across campaign activation domains.
• Align architecture decisions across teams to ensure consistency and maintainability.

Qualifications

Must Have

• Extensive backend engineering experience, with architectural ownership over services or distributed systems.
• Expertise in Python, FastAPI, and Flask with modern backend development patterns.
• Strong understanding of microservices, concurrency, async programming, and event-driven architectures.
• Proficiency with SQL and NoSQL databases (PostgreSQL, DynamoDB, Redis, MongoDB) and familiarity with lakehouse platforms.
• Experience with or strong willingness to work in PySpark and Databricks, including the medallion architecture (Bronze/Silver/Gold).
• Hands-on experience with Docker, Kubernetes, CloudFormation, and cloud platforms (AWS or GCP).
• Strong CI/CD experience using GitHub Actions, Argo, or similar tools.
• Deep knowledge of observability practices — logs, metrics, traces, performance analysis.
• Proven ability to write clean, testable, well-structured production code.

Nice to Have

• Experience with streaming or queuing systems (Kafka, Pub/Sub, SQS).
• Familiarity with AI/LLM systems and agentic workflow integration.
• Experience with Delta Lake, Unity Catalog, or other lakehouse governance and optimization tools.
• Prior experience with API gateway architectures, caching layers, or service meshes.
• Full stack engineering with product experience.
• A curious mind with memorable stories to share and hobbies that surprise people.

Core Competencies

Technical Expertise: You own backend architecture and data pipeline design across services, solving complex distributed systems and data engineering problems while defining reusable patterns that improve scalability, reliability, and developer velocity.

Leadership: You lead through influence — mentoring engineers, guiding architectural decisions, establishing engineering standards, and elevating backend craftsmanship without direct people management.

Product Impact: Your backend systems directly shape OneSuite’s performance, availability, and functionality across campaign activation for Search, Social, Commerce, Programmatic, and Measurement.

Innovation & Learning: You stay current with emerging architecture patterns, cloud-native technologies, data platforms, and backend frameworks. You introduce pragmatic innovations that deliver measurable engineering and product value.

Collaboration: You work across teams — aligning backend direction and ensuring platform cohesion across campaign activation domains. You communicate clearly, build consensus, and drive clarity in complex system discussions.
