About the company & team

🦄 About Us

Unicorn Pro is a performance marketing agency that works with affiliate dating products in the US and Tier 1 markets and is one of the largest partners by traffic volume in mainstream dating. At the same time, we deliberately build a small team based on the The Right Few principle — where every specialist is a master of their field and has a high degree of freedom to build processes according to their own vision.

We believe: strong results require the right people, not an inflated headcount. For us, team size is about speed, responsibility, and the ability to truly impact results, rather than getting lost in processes and roles. This is how we are building a new-format performance company: we don't chase scale, we scale each person's effectiveness. Technology makes this possible.

Hiring process

🧠 What the process looks like

  1. Initial Interview: a first meeting with the TA Manager where we discuss motivation, expectations for the role, and the context of previous experience. Behavioral questions are used to understand your work approach, responsibility, and decision-making style;

  2. Test Task: a paid practical assignment, as close as possible to the team's real tasks, usually requiring 6–8 hours. We evaluate your approach, priorities, and way of thinking, not just the final result;

  3. Technical Interview: a conversation with the CTO focused on practice. Real cases, typical tasks, and reasoning logic are discussed. No abstractions — only how decisions are made and what results back them up;

  4. Final Interview: an in-depth interview with the CMO/CEO. We walk through key career milestones: achievements, mistakes, decisions, and level of responsibility;

  5. Reference Check: the final stage — gathering feedback from previous colleagues or managers to confirm the overall picture.

Requirements

⚙️ Requirements

Tech stack:

  • 5+ years of Full-Stack experience with TypeScript/JavaScript (Node.js + React/Next.js);

  • 2+ years of experience in the ad-tech / affiliate / lead-gen domain (trackers, attribution, postbacks);

  • Production experience with the Anthropic API (6+ months of daily use of Claude as an engineering tool) and the Cloudflare stack;

  • Experience integrating with marketing APIs: Facebook Marketing API, Google Ads API, or similar — trackers, affiliate networks, ad platforms. OAuth, rate limits, webhooks, long-lived tokens, attribution, and postbacks;

  • BigQuery / SQL at the level of independently writing and optimizing analytical VIEWs;

  • Experience with agentic systems or workflow orchestration: Claude Agent SDK, n8n, LangChain/LangGraph, or custom solutions.

Work approach:

  • System design at a Senior level: justifying architectural decisions, understanding trade-offs, failure modes, observability, and cost implications;

  • Autonomy and product ownership: not waiting for a spec, taking tasks through to production without hand-holding — we have no PM;

  • Strong analytical skills: the ability to defend your point of view and make decisions based on data and metrics;

  • Outstanding results in previous roles: backed by concrete metrics and achievements;

  • Systematic thinking: the ability to think structurally, see the big picture while managing details;

  • Fluent Ukrainian;

  • English at B1 level: able to read API docs and write well-written support requests.
