🚀 We're Hiring: CRO Specialist / Funnel Manager

We're a high-volume performance marketing company — and we're looking for someone who is obsessed with conversion data and knows how to act on it fast.

This isn't a "build pretty pages" role. We need a ruthless optimizer. Someone who lives inside tracker dashboards, runs aggressive A/B tests, and knows exactly when to cut a losing funnel and scale a winner.

What you'll own:
→ Daily management, setup, and optimization of landing pages, offers, and traffic flows inside Keitaro (or equivalent trackers like Voluum / Binom)
→ Formulate hypotheses, launch split tests (headlines, layout, CTA, angles), and decisively cut losers while scaling winners
→ Work directly with media buyers — align funnel adjustments with incoming traffic sources, angles, and target audiences
→ Feed performance data and market trends back to copywriters and designers to brief high-converting creative assets
→ Monitor core KPIs (CTR, Conversion Rate, ROI, CPA) and translate raw data into strategic creative briefs

You're the right fit if you have:
✅ Hands-on experience with Keitaro (highly preferred) or equivalent self-hosted/cloud affiliate trackers — redirect rules, lander protection, and postbacks are second nature to you
✅ A background in direct-response marketing, affiliate marketing, or high-volume media buying (brand marketers or corporate UX designers — this role is not for you)
✅ True data literacy — you can open a tracker dashboard or spreadsheet, spot statistically significant trends instantly, and make decisions without hand-holding

Bonus points if you have:
⭐ Basic front-end skills (HTML / CSS / JS) to make quick landing page tweaks without waiting on a developer
⭐ Experience with spy tools (Adspy, Anstrex, or similar) to track competitor funnel trends

Comp: Base salary + performance-based commission

If you've diagnosed a sudden campaign drop, rebuilt a funnel from scratch, or turned a losing angle into a winner with data — we want to talk.

At Promova, we're reimagining language education to help today's minds unlock their full potential — building learning that's calm, personal, and genuinely useful for people around the world. Our 150+ teammates share one mission: connect people, bridge cultures, and support lifelong learners everywhere — in every country except aggressor states (yes, even Antarctica).

We pair AI with human creativity so people can speak with confidence and feel at home in a new language. If you like solving real engineering problems, building systems that hold up under load, and shaping the platform learners rely on every day — you'll fit in here.
 

We're looking for a DevOps Engineer to join our Core Infrastructure team.

Our infrastructure team is the backbone for Promova and several internal products. We build reliable, cost-aware infrastructure that lets engineering teams ship without fighting their tooling. From AI features and Kubernetes clusters to developer tooling and multi-cloud setup, you'll help shape the foundation the rest of the company builds on.
 

Why This Role

Own the platform. You'll have end-to-end ownership of core infrastructure across AWS, Hetzner, Cloudflare, Kubernetes, and modern platform tooling.

Work on problems that matter. You'll design infrastructure that scales, improve reliability, automate the manual parts, and build the foundation for the AI features learners use every day. We'll be honest: some of this is greenfield, some is untangling what already exists — both are on the table.

Shape where the platform goes. There's real room to standardize infrastructure across products, bring in automation, make developer experience better, and influence architecture decisions across the company.

Build in an AI-first team. AI is part of how we build products and how we work day to day. You'll help our infrastructure support AI workloads — and use AI in your own engineering workflow.
 

What You'll Work On

• Own and evolve Promova's core infrastructure across AWS, Hetzner, and Cloudflare.
• Design, build, and maintain Infrastructure as Code with Terraform.
• Build and improve CI/CD pipelines with GitHub Actions, Argo CD and self-hosted runners.
• Manage and optimize Kubernetes (K3s) and AWS ECS environments.
• Improve reliability, observability, and incident response with Grafana, Prometheus, Loki, and related tooling.
• Support the infrastructure behind our AI features and internal platforms.
• Improve cloud cost visibility and bring spend down where it makes sense.
• Build provisioning and onboarding automation that makes developers' lives easier.
• Strengthen platform security through secrets management, access control, and solid infrastructure practices.
• Collaborate with fellow infrastructure engineers and help shape engineering standards across teams.
   

What We're Looking For

• 4+ years as a DevOps, Platform, Infrastructure, or Site Reliability Engineer.
• Strong hands-on experience with AWS and modern cloud infrastructure.
• Solid Infrastructure as Code experience, ideally Terraform, Ansible.
• Experience running Kubernetes in production.
• Good understanding of CI/CD pipelines, GitHub Actions and Argo CD.
• Comfortable with Docker and Linux administration.
• Experience with observability tooling such as Grafana, Prometheus, and Loki.
• Experience with secrets management such as Vault or AWS Secrets Manager.
• Strong scripting skills (Bash and/or Python).
• An ownership mindset, good judgment, and clear communication.
• Experience mentoring teammates or leading infrastructure work is a plus.
   

Interview Process

• Intro call with the Recruiter
• Technical Interview
• Bar Raising Interview
• Offer

Sounds like you? Apply — and help build the platform behind how people learn languages.
