Our client is looking for a Tech Lead to drive the tech architecture behind their high-scale advertising platform. In this role, you’ll lead the technical direction for core microservices, APIs, and data pipelines that power campaign creation, optimization, and real-time analytics for millions of users. The position combines hands-on engineering with technical leadership: shaping architecture, mentoring engineers, and working closely with product and business teams to deliver reliable, scalable, and performant adtech solutions.
RESPONSIBILITIES
Own and evolve the backend architecture for the demand solutions and advertising dashboard, built primarily in Go, within a microservices environment
Design, build, and maintain reliable and scalable microservices that integrate with the dashboard (React / TypeScript) and other internal systems
Use event buses and streaming technologies (e.g. Kafka, SQS/SNS, Kinesis) to ensure reliable, asynchronous communication between services and to process billions of daily API events
Work with modern databases such as DynamoDB and columnar data stores (e.g. Druid, ClickHouse) to deliver low-latency APIs and support complex analytical queries
Design, maintain, and improve Druid queries and data flows that power fast and insightful analysis within the advertising dashboard
Define and maintain external partner APIs that allow advertisers to configure campaigns, upload creatives (images, videos), and access reporting and spend data
Lead and mentor a team of engineers: provide technical guidance, conduct code reviews, and foster a strong engineering culture focused on quality, performance, and ownership
Collaborate closely with product, business, and data teams to translate requirements into scalable technical solutions and ensure the platform supports growth objectives
Take an active role in architectural decision-making, long-term technical roadmap planning, and continuous improvement of the platform’s reliability and cost-efficiency
Champion engineering best practices (testing, observability, documentation, CI/CD) and help the team move fast while maintaining stability.
REQUIREMENTS
7+ years of experience in software engineering, including several years in lead roles (e.g. Tech Lead, Software Architect, Engineering Lead) in fast-moving product environments
At least 3 years of hands-on experience with Golang in a professional backend context (microservices, APIs, distributed systems)
Extensive experience with streaming systems (e.g. Kafka, Kinesis) and columnar/analytical databases (e.g. Druid, ClickHouse, Snowflake), including data aggregation and query optimization
Proven track record of technical leadership: making architectural decisions, guiding cross-functional teams, and delivering high-impact backend systems at scale
Background in high-volume data processing and building systems that handle large-scale event data with low latency
Strong understanding of cloud infrastructures such as AWS, Azure, or Google Cloud (AWS preferred), including managed services and cost-efficient architecture patterns
Experience leading and developing engineers: setting expectations, providing feedback, managing performance, and supporting career growth
Ability to bridge business and technology, comfortable working with product and commercial stakeholders, clarifying requirements, and aligning solutions with business goals
Excellent communication skills in English and a collaborative mindset suited for an international, cross-functional environment
NICE TO HAVE
Previous experience in adtech, martech, or other high-throughput, low-latency domains (e.g. real-time bidding, recommendations, analytics platforms)
Hands-on experience with React / TypeScript frontends and dashboards for analytics or campaign management
Knowledge of hybrid cloud / self-hosted architectures (e.g. Kubernetes, Apache ecosystem) and cost-optimization strategies at scale
Familiarity with A/B testing, experimentation, and data-driven feature rollout in product development.
