🚀 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.

The company is building the control layer for an energy-constrained world — deploying AI, machine learning, and reinforcement learning to optimize HVAC systems, industrial equipment, and large-scale energy loads across commercial buildings, factories, hospitals, and data centers. The focus is on real, measurable impact: autonomous control systems that drive 20–30%+ energy savings in production environments.

We're looking for a BMS Control Engineer / Forward Deployment Engineer (TPM) who will join the team. This is a hands-on role for someone who doesn't just design building automation systems, but has deployed, commissioned, and optimized them in real-world infrastructure.

This role is for someone who takes full ownership of field deployments — from site discovery to production rollout. You'll work at the intersection of BMS/BAS systems, HVAC controls, and AI-driven optimization, deploying autonomous control systems across commercial buildings, factories, hospitals, and data centers.

Your responsibilities will include:

• Own deployments end-to-end: site discovery, integration, commissioning, validation, and rollout;
• Install, configure, and commission BAS/BMS and PLC-integrated systems;
• Deploy gateways, sensors, submeters, and communications infrastructure;
• Perform startup, point-to-point testing, and controls validation;
• Interface with AHUs, RTUs, chillers, boilers, pumps, cooling towers, and VFDs;
• Integrate through BACnet (IP & MS/TP), Modbus, LON, and IP networks;
• Work with Niagara, Siemens, Honeywell, Johnson Controls Metasys, Delta, and other BAS platforms;
• Configure addressing, routing, communications, and device connectivity;
• Diagnose controls hardware, wiring, networking, protocol, and sensor issues;
• Support deployment of AI-driven and RL-driven control strategies;
• Own deployment schedules, communications, milestones, and execution;
• Coordinate customers, contractors, vendors, and internal engineering teams;
• Maintain deployment plans, commissioning reports, diagrams, and as-built documentation.

• Degree in Electrical Engineering, Mechanical Engineering, HVAC, or related discipline — or equivalent BAS/PLC/SCADA/DCIM experience;
• 2+ years of hands-on BACnet experience (IP & MS/TP);
• 2+ years of Modbus experience;
• 2+ years of HVAC Controls / DDC / BMS experience;
• Strong understanding of BMS/DDC systems, PLCs, PID loops, hydronics, and refrigeration;
• Experience with BAS platforms: Niagara (Tridium), Siemens, Honeywell, Johnson Controls Metasys, Delta;
• Hands-on commissioning and troubleshooting experience in the field;
• Ability to work independently and take ownership in customer-facing environments.

• Niagara (Tridium), EPA 608, NATE, or OSHA certifications;
• Experience in industrial facilities, healthcare, mission-critical environments, or data centers;
• Exposure to IoT, edge computing, SCADA, or DCIM platforms;
• Experience with LON protocol and IP networking in BAS contexts.

• Full-time engagement on a high-impact infrastructure project;
• Remote-friendly with on-site deployment work at client facilities;
• Direct work with cutting-edge AI and reinforcement learning applied to real-world systems;
• Measurable impact — 20–30%+ energy savings across live deployments;
• Opportunity to help define the future of autonomous building and industrial control systems.
