   HostZealot is an international hosting provider: VPS, dedicated servers, domains, and cloud services for customers worldwide. We're not just selling infrastructure — we're building long-term relationships. Our Sales & Billing team is the first and most consistent point of contact for most of our clients.

   We're looking for someone who genuinely enjoys helping people, knows how to stay calm under pressure, and takes real ownership of every customer interaction. If you want a role where your communication skills matter as much as your technical curiosity — keep reading.

What You'll Do

- Handle customer inquiries via tickets, email, and live chat — promptly and professionally;
- Consult customers on our products: VPS, dedicated servers, domains, locations, configurations, and add-ons;
- Guide customers through the full journey — from first question to order, payment, renewal, or cancellation;
- Resolve billing questions: invoices, payments, and service adjustments;
- Coordinate with Technical and Billing teams on complex cases, escalate when needed — with full context;
- Hand over open cases between shifts so customers never have to repeat themselves;
- Spot upsell opportunities — not to push, but to genuinely recommend when it's the right fit;
- Help improve response templates and the knowledge base.

What We're Looking For
 

Experience:
- 1+ year in customer support, helpdesk, sales, or any customer-facing role;
- Basic understanding of hosting concepts: VPS/VDS, dedicated servers, domains, DNS, IP — enough to explain them confidently to a client;
- Experience with ticketing systems, billing platforms, or CRM tools (any stack).
 

Languages:

- English B1+ — confident written communication; ability to hold a conversation with international clients;
- Ukrainian and/or Russian — fluent written communication.
 

Who you are:
- Customer-first mindset — you want to actually solve the problem, not just close the ticket;
- Stress-resistant — a frustrated client is a task to solve, not a reason to panic;
- Ownership-driven — you pick up a case and you see it through. No dropped balls;
- Fast learner — our product evolves. You read, absorb, and apply;
- Detail-oriented — especially in billing: small mistakes cost real trust;
- Multitasker — comfortable managing several conversations in parallel without losing context.

What We Offer

- 💰 Competitive salary (discussed at the interview);
- 🕐 Shift schedule agreed in advance, including evenings and occasional weekends;
- 🌍 Remote / hybrid — Ukraine;
- 🏖️ 21 days of paid annual leave;
- 🤒 Paid sick leave;
- 🎓 Onboarding on HostZealot products with Team Lead support;
- 📈 Clear growth path — your competencies grow, your grade and salary follow;
- 🌐 Real international experience — clients from across the globe, every day.

• Document architecture decisions, runbooks, and API contracts so distributed teammates can pick work up easily
• Partner with product, design, and clinical stakeholders to scope features and trade-offs
• Mentor more junior backend engineers and help raise the bar on backend practices across teams

What We're Looking For:

• 3+ years of professional backend engineering experience shipping production services
• Bachelor's degree in Computer Science, Software Engineering, or a related technical field — or equivalent practical experience
• Strong, hands-on Python skills, including modern type hints, async patterns, and idiomatic project layout
• Production experience with at least one major Python web framework (FastAPI, Django, or Flask)
• A proven track record designing, building, and evolving REST APIs (OpenAPI / Swagger), with familiarity with API versioning, pagination, and error-handling conventions
• Solid SQL skills with PostgreSQL or MySQL — comfortable writing migrations and tuning queries
• Strong testing habits with pytest across unit, integration, and contract tests
• Confident with Git, code review, and trunk-based or short-lived-branch workflows
• Strong analytical and problem-solving skills, with attention to long-term maintainability
• An ownership mindset — you take features from idea to production and stay accountable after launch
• Clear written and verbal communication in English, with the ability to work asynchronously across time zones
• Pragmatism: you balance correctness, speed, and complexity appropriately for the stage of the product

Nice to Have:

• Experience working in regulated environments (HIPAA, GDPR, ISO 27001, SOC 2, or medical-device software)
• Working knowledge of event-driven architectures (Kafka, RabbitMQ, SQS, Pub/Sub)
• Experience with containerization and orchestration (Docker, Kubernetes)
• Familiarity with infrastructure as code (Terraform, Pulumi, CloudFormation)
• Exposure to observability tooling (OpenTelemetry, Datadog, Grafana, Sentry)
• Hands-on use of AI-assisted development tools to accelerate delivery

• Experience with FHIR, HL7, or other healthcare interoperability standards
• Performance work on high-throughput or low-latency systems
• Hands-on experience deploying services to AWS, GCP, or Azure, and shipping changes through a CI/CD pipeline

What Success Looks Like:

• Demonstrated agency — you proactively identify technical gaps, architectural bottlenecks, or product opportunities and independently drive solutions to completion
• Reliable, well-tested services with healthy uptime and clear SLOs for the surfaces you own
• Predictable delivery: features shipped within agreed scope and timelines
• Strong code review and design contributions across the wider engineering team
• Growth and effectiveness of the more junior engineers you mentor
• Healthy incident response — time to detect, mitigate, and follow up on production issues
