Who We're Looking For

We're looking for a detail-oriented Operations Manager who will be the backbone of our daily operational process. You'll be responsible for data accuracy, active campaign monitoring, and vendor communication — making sure everything runs smoothly and any deviations are caught and resolved immediately.

Tasks

• Managing voice platform accounts: creating new ones, configuration, top-ups
• Communication with vendors (telephony, SMS): onboarding new ones, resolving issues with existing ones
• Working in the company's internal operations platform: data operations
• Client onboarding: creating client profiles in the platform, handing off the brief to the internal team
• Daily morning checklist control of active campaigns: comparing metrics against acceptable thresholds, checking client database uploads, confirming campaigns are running and haven't stopped, updating campaign statuses in the project management system
• Immediate escalation of deviations to the responsible manager
• Helping with monitoring and generation of Telegram accounts

Requirements

Must-have

• Accuracy with data. Transfers values between systems without errors, double-checks own work after filling in. Understands that one typo = a broken campaign.
• Execution discipline. Completes the daily checklist independently, at the same time, without reminders and without skipped items.
• Ability to compare fact against norm. Looks at a set of numbers and thresholds and spots what's out of range.
• Escalation reflex, not self-diagnosis. Sees a deviation → reports it immediately. Doesn't dig into it alone, doesn't hold onto it until end of day, isn't afraid to report bad news.
• Text communication as the primary work tool. Formulates requests briefly and clearly, runs several parallel chat threads without losing track.
• Persistence in driving an issue to resolution. With vendors: onboarding a new one, extracting an answer on an existing one. Doesn't stop at "they didn't respond."
• Learning agility. Picks up an unfamiliar interface or process from documentation and one walkthrough, then works independently.
• English B1, written.

Nice to Have

• Understanding of SIP trunking and telephony/SMS infrastructure is a plus.
• Experience communicating with vendors/providers.

What we offer

• Fully remote work format and flexible working hours.
• Competitive salary pegged to USD + performance bonuses.
• 24 days of paid vacation (sick leave, national, religious, and company holidays).
• A friendly communication culture and transparent processes.
• Dynamic work environment.
• Opportunities for professional development and career growth.
• No micromanagement — just trust, ownership, and freedom to experiment.
