About the Role
Appier is seeking a Software Engineer, Ad Serving to be the deepest technical problem-solver behind our advertising products. When a campaign underdelivers, when CVR drops without an obvious cause, or when a partner integration behaves unexpectedly, you are the person who reproduces the issue, reads the logs, queries the data, and gets to the actual root cause — then explains it in language a client or an account team can act on.
You will work at the intersection of ad serving, data, and machine learning: diagnosing delivery and performance issues across the full funnel from bid request to conversion, validating partner and supply integrations, and turning what you find into concrete improvements to our bidding and supply strategy. You will also build the tooling and playbooks that let the rest of the organization resolve these issues without you.
[The seniority/title is determined by job-related skills, experience, and evaluation after the interview.]
Responsibilities
- Own Tier 2/3 escalations across ad serving, tracking, data pipelines, and ML-driven bidding
- Perform root cause analysis on delivery failures, pacing anomalies, and performance metric fluctuations (CTR/CVR/CPA/ROAS)
- Debug OpenRTB integrations, VAST/video, SDKs, MMP postbacks, and conversion tracking (S2S, CAPI, SKAdNetwork)
- Use SQL to analyze large-scale bid/impression/conversion data and isolate anomalies
- Analyze supply-side data (SupplyChain object, ads.txt, sellers.json) to strengthen delivery strategy and flag invalid traffic
- Build internal tools and playbooks to reduce investigation time and enable team self-service
- Validate new partner integrations pre-launch
- Partner with Product, Engineering, and Data Science to drive platform improvements
- 3+ years in technical support, solutions engineering, or ad ops, incl. 2+ years with ad tech systems (DSP/SSP/ad server/MMP)
- Solid grasp of programmatic advertising (RTB, auctions, pacing, attribution, tracking)
- Strong SQL skills and proficiency in a scripting language (e.g., Python)
- Experience debugging APIs, logs, and distributed systems
- Experience with AI-assisted dev tools (Copilot, Cursor, Windsurf)
- Strong written/verbal English communication
- OpenRTB field-level debugging experience
- Large-scale data tools (BigQuery, Spark, Snowflake, ClickHouse)
- Supply chain transparency & IVT/MFA familiarity
- MMP experience (AppsFlyer, Adjust, Branch)
- VAST/CTV/Open Measurement SDK knowledge
- Monitoring tools (Datadog, Grafana, Kibana)
- Additional language skills (Mandarin, Japanese, Korean)
