Responsibilities

Own the end-to-end evolution of the evaluation platform: design and deliver step-level evaluation, automated regression analysis, and release quality gates that enforce production-grade standards across product and engineering teams; benchmark architecture and reliability against SOTA platform engineering practice at companies such as Grab and Sea.; Build and operate the data governance and security layer: deliver real-time PII/sensitive-data masking, schema synchronization, data ownership, versioned data dictionary, audit controls, and least-privilege governed access interfaces for AI Agents and internal tools — with no direct database connections and full auditability.; Design and ship reusable platform capabilities: shared SDKs, common workflow definitions, dataset/model/metric management APIs, and observability instrumentation that reduce per-team integration effort and enable new evaluation data sources to be onboarded within 1 day.; Drive platform reliability and observability: define and enforce SLA targets, build alerting and incident-analysis tooling, and establish quality-gate mechanisms that make evaluation results a trusted signal for release decisions.; Apply AI/LLM techniques where they replace brittle rule-based logic: identify evaluation or governance sub-problems where ML/LLM approaches outperform hand-crafted rules, prototype and validate them, and integrate proven approaches into the platform.; AI-native engineering: Actively uses AI-assisted tools for coding, debugging, analysis, documentation, and incident investigation to improve engineering efficiency and quality.

Requirements

5+ years of backend/platform engineering experience, including 3+ years designing and operating complex distributed systems in production; strong proficiency in Go and/or Java; Demonstrated experience building shared SDKs, reusable platform components, and production microservices with Kubernetes/Docker, HTTP/gRPC, retries, rate limiting, circuit breaking, auth, and fault isolation — shipped and operated at scale, not prototype-only; Strong command of database design, high availability, transaction isolation, idempotency, eventual consistency, observability, alerting, and incident analysis; able to reason from first principles about failure modes and recovery paths; Hands-on experience with workflow orchestration (e.g. Argo Workflows) and automated evaluation or validation systems, including execution, comparison, reporting, and quality gates; Proven experience with secure production-data access patterns: access control, auditing, data ownership, retention policies, least-privilege design, and PII/sensitive-data masking in a regulated or compliance-conscious environment; Experience with modern data infrastructure and processing frameworks such as Spark/Flink, Snowflake, Databricks, and Athena; familiarity with data warehouse, data lake, or data governance practices, including building data systems that are manageable, traceable, access-controlled, and secure.
