About the Role

We’re looking for a proactive and technically minded Technical Virtual Assistant to work closely with me and assist with a mix of operational, administrative, and automation-related tasks.

This is a hands-on, varied role. You’ll help me manage day-to-day operational requests, maintain and troubleshoot existing automations, work across different SaaS platforms, investigate issues, and support smaller technical and operational projects as they come up.

Some tasks will be technical, while others may involve checking information, managing access, following up with team members, researching an issue, updating documentation, or handling straightforward requests independently.

What You’ll Be Doing

• Maintain, update, and troubleshoot existing Zapier and n8n automations
• Create new workflows and make improvements to existing ones
• Investigate automation errors, failed workflows, data mismatches, and other operational issues
• Work across tools such as HubSpot, Airtable, Slack, ClickUp, and other SaaS platforms
• Check and manage user access, records, fields, and system configurations when needed
• Test forms, automations, workflows, and internal tools before and after changes
• Help investigate operational or technical questions and find the information needed to resolve them
• Handle straightforward requests and communicate or follow up with team members when needed
• Assist with small technical and operational projects
• Create and update simple documentation and SOPs
• Perform research and data checks when required
• Identify things that aren’t working as expected and proactively flag or resolve them where possible
• Help with other related operational and administrative tasks as needed

Requirements

• Previous experience as a Virtual Assistant, Operations Assistant, Technical Assistant, or similar
• Previous hands-on experience with Zapier, n8n, or similar automation tools
• Comfortable working with and learning different SaaS platforms
• Strong troubleshooting and problem-solving skills
• Ability to understand an existing workflow or process and investigate issues independently
• Excellent attention to detail, particularly when working with data, workflow logic, mappings, and system updates
• English level B2 or higher, both written and spoken
• Strong organizational skills and ability to manage multiple concurrent requests and prioritize effectively
• Reliable, responsive, and comfortable taking ownership of assigned tasks
• Proactive approach — able to notice potential issues or improvement opportunities rather than only following instructions
• Comfortable asking questions when necessary while also being willing to investigate and try to find solutions independently
• Availability with good overlap with U.S. business hours (approximately 9 AM–5 PM ET). Working hours can be flexible, but regular availability during this window is important.

Nice to Have

• Experience with HubSpot, Airtable, Slack, or ClickUp
• Basic understanding of APIs, webhooks, and JSON
• Experience troubleshooting integrations between different platforms
• Experience using AI tools such as ChatGPT or Claude for research, troubleshooting, or automation-related work
• Experience creating or maintaining SOPs and internal documentation

Who Would Be a Great Fit

You don’t need to be an automation engineer for this role. We’re looking for someone with enough technical experience to understand how automations and SaaS tools work, combined with strong resourcefulness, curiosity, and a willingness to figure things out.

This role would be a great fit for someone who enjoys variety and is comfortable with tasks that aren’t always accompanied by a step-by-step SOP. Sometimes you’ll receive a clear task; other times, you may be given an expected outcome, an existing workflow, or a problem and asked to investigate what’s happening and determine the best way forward.

We’re looking for someone who is hands-on, cooperative, proactive, and comfortable digging into processes, asking good questions when needed, and taking responsibility for getting things done.

Hi All,

We’re looking for an experienced Full-Stack Developer to join our remote team of 5, dedicated to supporting and developing several digital platforms for a single B2B client in Germany — a well-known hotel chain.

This is an hourly-based engagement, with an expected workload of approximately 100–140 hours per month.

We’re looking for someone with strong hands-on experience in Node.js, Next.js, and TypeScript, who can confidently work with an existing production codebase and take ownership of development tasks.

Main areas of work:

• Full-stack development and ongoing support of existing booking and customer-facing systems
• Backend development and API integrations
• Frontend development with Next.js / React

• Maintenance, refactoring, and continuous improvement of existing platforms. 

   

We’re flexible regarding the balance between backend and frontend work and can adjust it depending on your strengths and preferences. Experience with Strapi or another headless CMS, as well as a basic understanding of Kubernetes / cloud infrastructure, would be a strong plus.

A security-oriented engineering mindset is highly desirable. We expect developers to think not only about whether something works, but also about how it can fail, be misused, or create security risks.

For sure, we actively use AI tools in development and expect you to be comfortable working with them. At the same time, we are looking for an engineer who still thinks independently, understands the code being produced, questions AI suggestions, and can solve problems without blindly relying on generated answers.

For us, AI should make a strong engineer more productive — not replace engineering judgment.

The interview process consists of two stages:

1. Introductory call — to get to know each other, discuss your experience, expectations, and the project.
2. Live coding session with our CTO. During the live coding session, you are welcome to use AI tools and Google. We actually encourage using the tools you normally work with. The only requirement is that you share your screen and show how you use them, including what you ask AI or search for. We are interested not only in the final solution, but also in your reasoning, engineering decisions, and approach to solving problems.

We offer:

• Approximately 100–140 hours of paid work per month
• Flexible working hours
• Long-term cooperation
• Minimal communication and meeting overhead
• A skilled and collaborative remote team
• Work on real production systems with a long-term B2B client.

Thank you!

Hi! We're Netrocket, a digital agency with 12+ years of experience doing SEO and PPC for home service businesses in the US (HVAC, roofing, plumbing, electrical, remodeling). 

We're scaling sales on the US market and looking for a Sales Team Lead / Head of Sales — someone who first closes deals themselves, then builds and leads a team around them.

This isn't a "come and manage" role — you stay an active seller and the most credible voice in any sales conversation, while building the system and the team in parallel.

What you'll do

Selling (main focus for the first 3–6 months):

• Own and close your own pipeline: SQL → call → proposal → closed-won → new MRR
• Step in and rescue team deals when needed
• Find new channels for pipeline (Upwork, LinkedIn, outbound, inbound)

Building and leading the team:

• Set weekly/monthly targets, track conversion and pipeline health
• Build the system: CRM, scripts, follow-up sequences, call scoring, forecasting
• Coach by working alongside the team — call reviews, role plays, live deal support (not lectures)
• Hire new closers/SDRs as the team grows
• Figure out why deals are lost and adjust the process based on data

• Report to the CEO on revenue forecast and blockers

   

What we're looking for

• 5+ years in B2B sales, 1+ year leading a sales team (agency/IT background is a big plus)
• You're actively selling right now, not someone who stepped away from closing 2 years ago
• 2+ years selling digital marketing services: SEO, PPC, Google Ads, LSA, websites, lead generation
• Home services experience (HVAC, plumbing, roofing, electrical) is a strong plus
• Full sales cycle: discovery → qualification → presentation → objections → proposal → follow-up → closing
• You can speak to your own numbers: quota, close rate, average deal size, sales cycle, MRR/ARR
• Experience with CRM (HubSpot or similar), pipeline, dashboards
• Hands-on Upwork experience is a plus
• English C1+, natural American-style business communication (not scripted)
• Willing to work US hours (coverage through 6–8pm ET is a plus)

Location isn't critical  — we consider candidates from Ukraine, Eastern Europe, and Latin America (Colombia, Mexico, Argentina). What matters is communication, US cultural fluency, track record, agency experience, and ownership.

What we offer

• Base $2,500–3,000/mo + strong variable → 
• After proven results and managing a team of 2–4 salespeople: base $3,500–4,000 + team override →
• Team performance bonus — the better your team does, the more you earn
• Fully remote, no micromanagement, no bureaucracy
• Real ownership — you build the sales function, not just execute a plan
• A product you can sell with confidence: real results, real clients, real case studies
• A clear growth path to Head of Sales as the team scales

If you're already selling digital marketing services to US SMBs and want to do more than just close deals — you want to build and lead a sales team from the ground up — apply and we'll tell you more at the screening call.
