Tech Lead (f/m/d)

• AdTech & Anti-Cheat Domain Expertise: You understand the mechanics of digital advertising (attribution, publisher monetization, traffic quality) or bring experience from adjacent anti-abuse environments like gaming anti-cheat. You will act as the escalation point for BI, Product, and Support, translating complex abuse patterns into concrete technical solutions.
• Reverse Engineering & Exploit Analysis: You have an adversarial security mindset. While our core SDK team develops production client libraries, you understand iOS and Android internals well enough to decompile binaries, understand and use hooking of APIs and work with frameworks to root/jailbreak devices (e.g., Magisk, Xposed, KernelSU, Dopamine), and reproduce emulator- or bot-driven exploits in a sandbox environment to find the root cause.
• Large-Scale Telemetry & Data Forensics: You can query and analyze billions of daily events across distributed databases (Trino SQL, DynamoDB, ScyllaDB). Using data analysis tools and LLM-assisted workflows, you quickly isolate anomalous clusters, model suspicious traffic patterns, and turn raw telemetry into actionable detection heuristics.
• Distributed Systems Observability & Profiling: You are comfortable working with high-throughput event pipelines. Leveraging Grafana, Kibana, and distributed tracing, you monitor system health, diagnose bottlenecks across Kafka and SQS queues, and verify that detection APIs maintain low-latency response times under heavy load.
• Technical Leadership & Team Enablement: You will serve as the technical lead for our new Fraud Operations unit within the Anti-Fraud Solutions team. Partnering with the Product Lead, you will drive technical strategy, conduct meaningful code and architecture reviews, and mentor engineers. We value clear communication and pragmatic decision-making over years of formal management hierarchy.
• Pragmatic Engineering & Rapid Mitigation: You are a hands-on engineer who can read, debug, and review Go microservices without needing to be a Go purist. Working alongside Backend, Mobile, and Data Science teams, you will prototype detection logic, deploy verified mitigation rules, and automate responses to emerging attack vectors.
