At our company, everyone is on a first-name basis. There&# 039;s no unnecessary bureaucracy. We work together, support each other, and move toward common goals. At Sempico Solutions, you&# 039;ll quickly feel what it means to be a real part of the Team.

Requirements

At Sempico Solutions, we&# 039;re looking for a proactive and technically curious Technical Support (Escalation Level 1) who is ready to be the first human line of support in the chain: AI в†’ L 1 (you) в†’ Support Specialist в†’ CTO.

You are someone who enjoys digging into new systems, isn&# 039;t afraid to read logs and documentation, and communicates clearly and calmly — even under pressure.

Our ideal candidate has:

• Ability to clearly express thoughts in written communication — structured, professional, client-oriented.

• Responsibility, honesty, and punctuality: you close tickets properly, or escalate with full context — you don&# 039;t leave things hanging.

• Analytical mindset: ability to break a problem into components, form a hypothesis, and verify it.

• Confidence working in Linux terminal (navigation, reading logs, basic commands) and Windows.

• Basic knowledge of network protocols (TCP/IP, DNS, HTTP) - you can explain what ping, traceroute, and nslookup tell you.

• Basic ability to read tcpdump output at packet level.

• Basic SQL skills (SELECT, WHERE, JOIN) - for diagnosing account state, traffic, and DLR records.

• Readiness to work across multiple channels simultaneously (Telegram, WhatsApp, Teams, HelpCrunch, email) and prioritize in real time.

• Fluent Ukrainian (C 1 or native) and English at B 2 Upper Intermediate level or higher (both spoken and written).

• Calm and professional behavior with clients, even in difficult conversations - no emotional reactions, no empty promises.

• Eagerness to learn and grow - you try to figure things out yourself first, but aren&# 039;t afraid to ask.

• Be technically equipped - our work requires being online during working hours regardless of power outages. Reliable internet connection and charged equipment are a must!

Nice to have:

• Experience in technical or customer support (IT / telecom).

• Basic knowledge of SMS / SMPP / CPaaS.

• Experience with HelpCrunch, Zendesk, Intercom, or similar ticketing systems.

• Basic scripting skills (Bash / Python) for routine tasks.

• Experience with Jira / Trello.

• Experience maintaining documentation or FAQ.

• Technical education or self-education in networking / IT.

What You&# 039;ll Do

• Handle client tickets escalated from AI Support - perform first-level diagnosis and resolve or escalate with full context.

• Diagnose issues at the first human level: read logs, query the database, analyze tcpdump output.

• Work across all client communication channels: Telegram, WhatsApp, Teams, HelpCrunch, and email.

• Escalate to the Support Specialist with complete context - steps to reproduce, hypotheses, relevant data - so the next person can pick it up without asking questions.
