InfluenceProServices builds services, tools, and infrastructure that drive marketing business growth and help teams scale efficiently. Every day, we tackle complex technical and operational challenges, enabling our customers to push boundaries and achieve greater success.
We are building an internal anti-fraud system to detect and prevent fake leads and bot-driven traffic in web forms.
Attackers use anti-detect browsers, residential proxies, VPNs, and partially real user data to bypass cloaking and validation systems.
We are looking for a Software Engineer who can design and implement detection systems based on: * browser fingerprinting * behavioral signals * network-level anomalies
This is not a typical backend role. It requires a deep understanding of how browsers, networks, and bot systems actually work under the hood. Responsibilities * Design and implement fraud detection systems for web traffic and lead generation * Build and improve fingerprinting pipelines across browser, device, and network layers * Analyze and detect patterns of bot traffic and fake form submissions * Work with signals such as: * Canvas / WebGL / Audio fingerprints * TLS / IP / proxy characteristics * Browser inconsistencies and automation traces * Develop scoring and evaluation systems using Go or Python * Reverse-engineer bot behavior and anti-detect browser techniques * Continuously improve detection rules and heuristics based on real attack data
Experience and Skills * Strong JavaScript knowledge (not frameworks), including: * prototypes * property descriptors * event loop * timing APIs * Solid understanding of browser internals, including: * DOM * rendering pipeline * WebGL * Canvas * Backend development experience, preferably with Go or Python * Understanding of fingerprinting techniques: * browser fingerprinting * device fingerprinting * network fingerprinting * Experience detecting bots, fraud, or abnormal traffic patterns
Nice to Have * Experience with anti-detect browsers or automation tools * Experience in ad tech, affiliate, or traffic quality * Familiarity with residential proxies and bot infrastructure * Contributions to fingerprinting- or security-related projects * Experience with: * FingerprintJS * browserleaks-like tools * bot mitigation systems
What We Offer * Paid vacation and sick leave * The opportunity to work in a dynamic team of professionals driven by a shared passion for product innovation and real impact * A flat structure with no micromanagement and full ownership of your work * A remote-first culture with flexible working hours
