Web is where we’re building what comes next. In 2025, web grew 10x year-over-year — and by mid-2026, we’re already close to repeating that entire year’s numbers. Now we’re looking for a Head of Web Growth to join one of our Business Units and take the web even further: from a strong growth engine to the dominant revenue driver across its app portfolio.

You’ll report to the CEO of the BU and lead a team of growth managers, who are already delivering solid results. Your job is to help them aim higher and build the systems that make strong performance repeatable.

What you will do:

• Own web revenue performance across the unit and set the direction for how the team moves these numbers
• Audit current web growth processes and build the strategy from there
• Lead the shift to web-to-web as the primary growth format — scaling what works and fixing what doesn’t
• Lead, mentor, and develop a team — raise the hard skills bar, drive accountability, and create the kind of environment where ambitious targets feel energizing rather than exhausting
• Work closely with heads of product, marketing, analytics, and engineering to move initiatives from strategy to execution

What you should have:

• 5+ years of experience in growth or product marketing within subscription-based environments, with a strong focus on web and web-to-web
• 3+ years of leadership experience managing growth teams and driving cross-functional collaboration across product, marketing, analytics, and engineering
• Proven track record of taking subscription products through different stages: you’ve launched from scratch, scaled what was already working, and diagnosed why something that should be growing isn’t
• Deep understanding of unit economics and web growth metrics: CAC, LTV, ROAS, retention, churn, funnel conversion — and how they connect to each other
• Understanding of how LTV prediction models are built and what drives them
• Experience with payment infrastructure: you know how subscription billing works end-to-end
• Hypothesis-driven approach to growth: you build experiments, read results honestly, and iterate fast
• Sharp analytical thinking — you work comfortably with numbers, notice what others miss, and can translate data into decisions
• Solid people management instincts — you know how to develop talent
• Strong written and spoken English

What we offer:

• Results-oriented colleagues committed to scaling impactful products. Your team will help you achieve the most ambitious goals
• Remote-friendly work environment with high autonomy and minimal bureaucracy
• Competitive fixed salary+ generous performance-based bonus
• Medical insurance (depending on the location)

• Paid vacations, sick days, and other benefits

We're looking for an SRE / DevOps engineer to build the reliability layer for a platform that commands live power plants. No unified log pipeline, no dashboard anyone watches, no rehearsed restore - the app runs in production, the layer underneath it is a set of habits. You decide what the observability stack looks like, what an alert may wake a person up for, and how failover is designed and tested.

Second part is physical: with the Infra Lead, dispatch control room - workstations, UPS, local network, secured remote access to plants. Grafana in one tab, a rack in the other.

Must have

• 4+ years SRE / DevOps / systems engineering, Linux daily: services, systemd, storage, performance diagnostics
• Real experience with physical or VPS servers, not cloud consoles only - UPS, RAID, remote management. Cloud-only profile is an automatic no
• Cloud VMs: provisioning, patching, hardening, capacity planning, TLS, nginx
• Docker / Docker Compose in production: dev/staging/prod layouts, registry, zero-downtime deploys
• Observability you built yourself: Prometheus + Grafana or equivalent, log pipeline (fluent-bit / ELK class), and an alerting philosophy you can defend
• Redundancy you tested: PostgreSQL backup/restore and replication, Redis failover, measured recovery. You can describe a backup you personally restored
• Networking: WireGuard or similar, firewalls, DNS, TLS, diagnosing cloud ↔ office ↔ plant links
• CI/CD as code (GitHub Actions or similar), promotion through environments
• Bash + Python for automation
• English B2
