Role
Who you are
- We're looking for a self-starter who finds problems, frames them, and fixes them, and who makes the engineers around them better in the process
- 5–8 years of software engineering experience, with meaningful time in distributed or high-scale backend systems
- Strong proficiency in at least one modern, high-performance language; TypeScript and/or Golang strongly preferred
- Solid understanding of distributed systems concepts: consistency, availability, fault tolerance, event-driven architecture, and service orchestration
- Experience building and maintaining microservices in production at meaningful scale; async messaging (Kafka, Pub/Sub) or workflow engines a strong plus
- Comfortable with CI/CD pipelines, containerization (Docker, Kubernetes), cloud infrastructure (AWS, GCP, or Azure), and debugging production issues using monitoring and distributed tracing
- Active user of AI coding tools (Cursor, Copilot, or equivalent) with real, demonstrated productivity gains
- B.S. or higher in Computer Science, Engineering, Mathematics, or equivalent practical experience; AdTech, programmatic, or real-time systems experience a plus
What the job involves
- The Kargo Workflow Platform powers our entire AdTech engine, and we're modernizing it
- As a Senior Engineer on the team, you'll design and build distributed services that are reliable, observable, and built to last — owning projects end-to-end and partnering across engineering, product, and data
- Design and build distributed services for the Workflow Platform modernization, thinking about failure modes, retry logic, and observability from the start
- Own significant projects end-to-end — from design through deployment and post-launch optimization — with minimal hand-holding
- Improve platform health through latency reductions, fault tolerance, and observability enhancements with measurable outcomes
- Use AI-assisted development tools fluently to ship faster, and actively share what's working with teammates
- Raise the quality bar through code reviews and design discussions, contributing well-reasoned opinions
- Partner with Product, Data, and cross-functional stakeholders, translating fluently between technical and non-technical
- Mentor less experienced engineers through pairing, documentation, and patient, constructive guidance
Our take
The way in which advertisers reach out to their audiences has changed dramatically over the last decade, primarily due to the invention of the smartphone. Whilst mobile ads have existed since the beginning of smartphones, most rely on technology that was built for desktops, resulting in bad advertising and missed opportunities.
Kargo provides a mobile advertising platform for marketers and publishers, helping them to deliver better business outcomes by leveraging advertising technology designed specifically for mobile. The company achieves this by directly integrating optimized impressions from the best-performing publishers within its specialized supply, using tangible identity metrics to analyze and improve advertiser KPIs, and overall, by facilitating personalized, mobile-optimized advertising.
The company acquired Videobyte (a video advertising platform for Connected TV) in early 2023 to expand operations into the relatively young digital TV industry and its lucrative TV formats. Bringing video, publisher tools, and unique formats to Kargo's omnichannel, this acquisition indicates a diversification of media for the advertising provider, which already has a firm grip on both mobile and desktop advertising platforms. On top of that, 2025 funding is being used for R&D of new AI-powered products and to broaden market reach.
