Senior Backend Engineer

About the Role

Vantage is hiring a Senior Backend Engineer. In this role you'll focus on building features and integrations with partner systems while acting as a backend subject matter expert and mentor for our engineering team. Expect heavy use of external APIs to pull data, as well as designing and delivering APIs that both receive data from and push data to external sources. You'll work with large datasets, perform hands-on coding, and keep our services reliable and fast.

In this role you'll be called on to support multiple product teams to uphold sound architecture, high code quality, and on-time delivery. You'll be a trusted go-to reviewer for SQL and Django ORM changes, set clear standards for database and service performance, and guide design and trade-off decisions that keep the platform scalable.

This posting is for an existing vacancy (backfill).

Minimum Requirements

• 6+ years of professional experience with a strong record in software development, testing, software design, and architecture.

• Advanced SQL expertise beyond an ORM user. Comfortable reading DB queries, designing indexes, tuning complex joins, and refactoring queries for reliability and speed.

• Strong Python and Django experience building production services and APIs.

• Experience as a gatekeeper for database performance in code reviews and in debugging sessions.

• Experience with MySQL and/or Postgres.

• Proven ability to troubleshoot and debug production code using logs, metrics, and traces.

• Experience addressing performance and optimization problems with a demonstrated ability to both diagnose and prevent issues.

• Experience with cloud platforms such as Azure, AWS, or GCP.

• Track record of effective mentoring and knowledge sharing.

• Experience with B2B API integrations.

• Bonus: Experience with Celery, RabbitMQ, and OTEL. A degree in Computer Science or a related field is a plus.

Role Responsibilities

• Serve as one of the owners for application and database performance. Review pull requests with an eye for query cost, indexing, and data access patterns, and drive improvements across the codebase.

• Own external API integrations and data exchange. Build and maintain reliable partner connectors, including authentication, rate limiting, and retries. Design and evolve internal and partner-facing APIs.

• Design and ship backend features and services in Python and Django with predictable latency and high reliability.

• Diagnose production issues, lead debugging sessions, and improve observability using logs, metrics, and traces.

• Proactively identify performance risks, create plans to eliminate them, and coach the team on best practices to prevent regressions.

• Maintain strong automated test coverage and clear documentation that support safe changes and fast delivery.

• Mentor engineers through pairing, design reviews, and actionable feedback that raises the standard of the team.

• Contribute to architectural discussions and solutioning to ensure scalable and effective product decisions.
