•  Integrate documentation discovery into internal tools such as Backstage.

Operational Metrics Reporting:

• Contribute to a centralized operational reporting solution consolidating platform, reliability, and business KPIs.
•  Implement drill-down dashboards for engineers, aggregated SLO/SLA views for tech leads, and executive-level KPI rollups.
•  Integrate data pipelines from Prometheus, Grafana, Datadog, and related observability tools.

Collaboration & Leadership:

• Partner with engineering, analytics, platform, and infrastructure stakeholders to deliver high-impact solutions.
• Mentor peers, sharing best practices in APIs, search, and observability.
• Own projects end-to-end: design, implementation, deployment, monitoring, and iteration.

Required Skills and Qualifications:

• 7+ years of experience in software engineering, with a strong background in platform/data engineering.
• Strong proficiency in SQL and data tooling (Redash, Looker, Mode, or similar).
• Experience with OpenSearch/Elasticsearch and/or vector databases (ChromaDB, Pinecone).
• Familiarity with observability platforms (Grafana, Prometheus, Datadog).
• Proficiency in at least one backend language (Java, Python, or JavaScript/TypeScript).
• Hands-on experience with API design, REST, GraphQL, and microservices architectures.
• Strong understanding of workflow automation tools and middleware platforms.
• Proven ability to drive cross-functional programs, managing priorities and dependencies effectively.
• Strong communication skills with both technical and non-technical stakeholders.

Nice-to-Have Skills:

• Experience managing PDL/Redash at scale, including multi-team governance.

• Knowledge of CI/CD pipelines and DevOps practices.
• Experience with event-driven architectures (Kafka, Pub/Sub).
• Open-source contributions in analytics, search, or observability domains.

This role is ideal for an engineer who thrives at the intersection of data platforms, search infrastructure, and observability, and wants to build systems that enable every team at Upwork to work smarter and faster.
