Your day (or evening) may look like this:

• Planning and coordinating the dispatcher team’s workflow: assigning tasks based on dispatcher workload, strengths, and current operational priorities.
• Participating in daily dispatch operations: selecting trucks for orders, assigning field staff teams to jobs, and making sure each order has the right crew and vehicle.
• Distributing field staff teams across orders based on schedule, location, job complexity, availability, and operational needs.
• Monitoring whether orders are properly covered: team assigned, truck assigned, notes updated, and all key details checked.
• Supporting dispatchers during busy hours, complex jobs, delays, changes, or unexpected situations.
• Monitoring task completion and quality of service.
• Adapting and training new dispatchers: giving instructions, explaining processes, providing feedback, and supporting their growth.
• Participating in creating and documenting processes that are missing or need improvement.
• Maintaining constant communication with dispatchers and other departments: Sales, Customer Support, HR, drivers, and field staff.
• Resolving non-standard situations: vehicle breakdowns, delays, staffing shortages, schedule changes, client issues, or team replacements.
• Updating CRM and reports: tracking orders, comments, payments, fines, tolls, vehicle maintenance alerts, and other operational details.
• Suggesting process improvements to increase speed, structure, and quality of operations.
• Supporting team morale: motivating, praising, and helping colleagues during peak hours.
   

This role is a great fit if you:

• Can combine leadership with hands-on operational work.
• Can manage multiple tasks and keep the team organized.
• Stay calm under pressure and think clearly.
• Take responsibility for team results, not just your own tasks.

That’s why we are looking not just for a Customer Care Specialist, but for someone who is not afraid of challenges, thinks outside the box, and is passionate about building a large-scale European project born in Ukraine.

You’re our perfect match if you:

• Have B1 level or higher proficiency in Latvian and communicate fluently in Ukrainian;
• Are proactive and not afraid to drive change: identify opportunities for process improvement and openly suggest the best solutions for the business;
• Are flexible and creative: make decisions quickly and confidently step beyond standard scripts and processes when needed;
• Thrive in a fast-paced environment: as the company grows rapidly, adapting quickly to change is your superpower;
• Demonstrate a high level of empathy: understand customers' emotions, adapt to their communication style, and genuinely want to help;
• Feel confident working with Microsoft Office.

What you’ll be doing:

• Monitor international shipments at every stage to ensure on-time delivery and identify recurring delays or process bottlenecks;
• Handle inbound and outbound communication via phone, email, messaging apps, and live chats;
• Contact customers to resolve non-standard situations, including delivery clarifications, customs data updates, and notifications regarding unsuccessful delivery attempts;
• Advise customers on services, pricing, basic customs regulations, and export/import procedures;
• Collaborate with internal teams and international colleagues to escalate and resolve complex cases, up to CEO level when necessary.

What we offer:

• Freedom of choice: work where you feel most productive — in a hybrid format or fully remotely;
• Official employment: social benefits, paid sick leave, vacation days, and business trips covered according to company policies;
• Voluntary health insurance and life insurance;
• All the equipment you need to work comfortably and efficiently;
• A growth-oriented environment: opportunities to develop your skills, participate in new projects, and build your career within the company.

Hiring Process:

• AI Interview — Complete a short AI-powered interview to help us learn more about your experience and communication skills.
• Recruiter Interview — Meet with our recruiter to discuss your background, the role, and answer any questions.
• Head of Support Interview — A final interview with the Head of Support to assess your skills and team fit.

Everything starts with a first step. Send us your CV today and join us in creating an outstanding customer experience together!

We are Proxy-Seller, a European product IT company providing proxy services for automation, parsing, marketing, and cybersecurity.

We’re looking for a B2B Content Specialist who can help us turn complex technical topics into clear, useful, and conversion-focused content. This role is a great fit for someone who understands B2B funnels, can work confidently with different content formats, and is not afraid to bring their own perspective to the table.
 

What you’ll be responsible for:

• Writing case studies based on interviews with internal team members, focusing on results, client challenges, and how we solved them.
• Creating use cases that translate product capabilities into clear, vertical-specific stories.
• Writing LinkedIn posts for the company and supporting ongoing organic presence across key social channels.
• Creating a landing page and UX copy in close collaboration with the Head of Content and the marketing team.
• Supporting webinar content: promo copy, speaker interview preparation, script refinement, and post-event repurposing.
• Writing gated content such as reports and vertical guides that can later be used across socials, email, and PR.
• Creating YouTube scripts and briefings for video production.
• Writing copy for sales decks and email sequences for onboarding, nurture, trial activation, re-engagement, and win-back flows.
• Helping build or improve automation workflows in tools like n8n, Zapier, or Make.
   

We’re a strong match if you:

• Have 3+ years of experience in B2B content marketing in a technical or product-led environment.
• Have basic understanding of the data scraping and proxy industries.
• Understand B2B funnels and can think in TOFU/MOFU/BOFU terms, not just in isolated pieces of copy.
• Know how to turn a technical product feature, protocol, or use case into marketing-grade content that still feels human and clear.
• Have experience writing different types of content (case studies, website copy, social media posts, and email content).
• Can adapt tone and style for different formats, from technical explainers to storytelling-driven assets.
• Use AI and automation tools confidently in your workflow and are open to improving processes.
• Have advanced English and can write clearly for a technical audience without oversimplifying the message.
   

It would be a plus if you:

• Have experience in the proxy, scraping, anti-detect, or network infrastructure niche.
• Have a background in Linguistics or Marketing.
• Have written YouTube scripts that hold attention and support conversion.
• Have experience with webinar content or owned the content side of a webinar program.
• Have hands-on experience with automation tools such as n8n, Zapier, or Make.
   

What do we offer?

• The chance to work on a wide variety of content formats, from case studies and landing pages to scripts, emails, and campaign assets.
• Close collaboration with the Head of Content, so you’ll have clear ownership but also support in execution.
• The opportunity to work with modern AI and automation tools as part of your daily workflow.
• Full-time remote role with flexible working hours (you can adjust your schedule as long as deadlines are met).
• Education covered by the company (professional courses, corporate English).
• Internal growth & career development — many of our managers and team leads have grown into their leadership roles from within the company.
• Employee referral program.
• Ability to influence processes: we are open to initiatives and improvements
• PTO: 21 calendar days of vacation, 12 days off, 7 days of sick leave (may be more if necessary). Public holidays are days off.
   

We’re looking for proactive people who do not wait for tasks to become urgent before acting, those who are not afraid to stand by their point. If you like bringing clarity to complex topics, collaborating across teams, and improving how content works in practice, we’d be happy to hear from you.
 

Our hiring process:
Intro call with a recruiter → Test task → Technical interview with the team → Offer
 

*We usually review applications within 3−5 business days

We share feedback if we’re able to move forward together. If this role isn’t the right match for now, we’ll keep your resume in our database and gladly reach out when a suitable opportunity comes up
