PII cleanup or corrections, and targeted data fixes Technical Requirements • Programming Language — Experience writing excellent production code in Node.js (JavaScript/TypeScript), Rust, or similar.
- Database — Experience with advanced queries using MySQL, Postgres, SpannerDB, or similar, since investigations will require digging into raw data.
- Architecture — Experience implementing Microservice architecture, Event-driven architecture, or similar — at least 4–5 years total (or 2 years Microservices + 2 years API development).
- API Layer — Experience building GraphQL, gRPC, and REST APIs.
- Infrastructure — Working knowledge of Cloud (GCP/AWS), Docker, Terraform, Kubernetes, Kafka, S3/GCS Buckets, Artifactory, BigQuery/Data Lake, etc.
- APM — Working knowledge of application monitoring and logging systems like Grafana/Prometheus, New Relic, Kibana, Datadog, or similar.
- BI Tools — Experience with BI tools like Looker, Tableau, etc.
- Domain — Fintech experience preferred.

Preferred Qualifications • 8+ years of experience in software engineering, quality engineering, SDET, or technical operations supporting production systems.

- Solid focus on operational quality and correctness in customer-impacting workflows, particularly in financial or regulated domains.
- Comfort executing and improving runbook-driven operational processes, including identifying gaps, edge cases, and documentation issues.
- Proven ability to investigate and validate production issues, including reproduction, confirmation, and defect clustering to reduce noise.
- Ability to make small, scoped improvements to existing systems (e.g., test fixes, configuration changes, minor data corrections, or internal tooling enhancements).
- Working knowledge of logs, metrics, and basic service observability for debugging and validation.
- Clear, effective collaboration with Customer Experience, Product, and Engineering teams to close feedback loops.
