As a Software Engineer on the Identity Service Team, you will contribute to the design, development, and delivery of scalable, cloud-native backend systems that power identity resolution, audience targeting, and high-throughput advertising workloads. You will build and maintain high-performance, low-latency microservices primarily using Golang within an AWS/EKS environment while helping drive reliability, scalability, and operational excellence across distributed systems.
In this role, you will work closely with cross-functional teams including Product, Architecture, SRE, QA, Compliance, and Data Engineering to deliver resilient and observable platform capabilities.
The ideal candidate has strong experience developing cloud-native microservices, managing CI/CD pipelines, working within modern data ecosystem technologies, and is a collaborative engineer who thrives in fast-paced agile environments and passionate about building reliable, scalable backend platforms.

Job Description

Core Responsibilities:

• Develop and maintain; API's, Microservices, and components for audience/identity workflows (e.g., ID mapping, audience lookup, segment evaluation).
• Own end-to-end features from design through deployment: requirements clarification, technical design, implementation, code review, automated testing, observability, and rollout.
• Ensure reliability and operational excellence of identity services by implementing robust logging, metrics, alerts, and dashboards.
• Optimize identity targeting performance and latency, including query patterns, matching strategies (linkages), and data-access paths (e.g., Aerospike, Kafka, Snowflake, S3) to support high-throughput ad-serving and bidding workloads.
• Safeguard data quality across identity pipelines by adding validations, (appropriate) thresholds, and automated checks for ingest, transformation, and targeting logic.
• Collaborate closely with product, architecture, SRE, QA, and compliance to refine requirements, align on designs, ensure privacy, and validate the effectiveness of engineering solutions.

• Participate in escalation and production support workflows (P1/P2), performing root cause analysis for identity-targeting issues, proposing fixes, and implementing durable preventative measures.
• Drive continuous improvement and tech-debt reduction in the identity targeting codebase, simplifying complex logic, improving test coverage, and aligning services with modern cloud/platform standards.
• Mentor and collaborate with peers (junior engineers, data engineers, QA) by providing constructive code reviews, sharing domain knowledge on identity targeting, and contributing to onboarding and documentation

Qualifications:

• Bachelor's degree in Computer Science, Engineering, or related field, or equivalent practical experience.
• 3+ years of software engineering experience building scalable backend services and distributed systems.
• Strong programming experience with Golang preferred; additional experience with Java or Python microservices is valuable.
