We are now looking for an IT Support Engineer to join our team and provide reliable technical support, ensuring stable access to corporate systems and smooth daily operations across the company.

Main responsibilities:

User Support (L1)

• Receive, analyze, and process requests through the service desk.
• Provide prompt assistance to employees regarding:
  - access to services (Google Workspace / Okta / Slack / GitHub, etc.);
  - corporate VPN operations (Pritunl);
  - corporate devices and workstations (Windows/Mac);
  - basic networking issues;
  - corporate security policies.
• Ensure SLA compliance for first response time and resolution time according to ticket priority.

Incidents and Requests

• Classification and escalation of complex requests to the L2 support team.
• Maintaining clear communication with users until task completion, including providing regular updates on long-running tickets and final confirmation of resolution.
• High-quality ticket documentation, including context, actions taken, and outcomes, in a format suitable for audits and knowledge base contribution.
• Participation in backlog reduction and continuous improvement of support processes.
• Tracking recurring requests and initiating updates to documentation or automation to reduce their frequency.

Administration and Routine Tasks

• Creation and deactivation of users in corporate systems.
• Provision of access according to roles and internal policies.
• Updating documentation and the knowledge base.
• Ensuring compliance with standard procedures (onboarding/offboarding).
   

About you:

• 1+ years of experience in technical support for 500+ users or equivalent hands-on experience administering corporate IT infrastructure.
• Hands-on experience administering Google Workspace (user creation/deactivation, groups, OUs, access management) and Okta or a similar SSO provider (SAML/OIDC, MFA, provisioning).
• Experience configuring corporate VPN clients (Pritunl or similar) on macOS and Windows, with the ability to troubleshoot common connectivity issues.
• Experience supporting Windows and macOS environments at an end-user level: software installation/updates, permission management, basic network troubleshooting, and MDM-related tasks.
• Understanding of core networking concepts such as DNS, DHCP, Wi-Fi/Ethernet, and proxies — enough to localize issues to a specific layer rather than guess.
• Strong problem-solving, communication, and service-oriented mindset.
• Ability to clearly document tickets, including issue context, tested hypotheses, actions taken, and resolution. Understanding that a ticket is not only a response to the user, but also an artifact for the team and the knowledge base.
   

Will be a plus:

• Experience working with service desk systems (Jira Service Management, Freshdesk, etc.), including workflow and SLA configuration.
• Understanding of ISO/IEC 27001 processes or participation in related projects.
• Experience interacting with a large number of users (500+).
• Basic scripting skills (Bash / PowerShell / Python) for automating routine tasks.
• Experience using AI tools (ChatGPT, Claude, GitHub Copilot, etc.) to speed up daily work: writing scripts, parsing logs, generating response templates, and analyzing errors. Understanding where AI is helpful and where it may be misleading.
• Experience or strong interest in infrastructure/DevOps practices, including GitHub Actions, containerization, and basic cloud services.

Health insurance & corporate doctor.

Support for sports events. We cover entry fees and encourage the team to compete and participate together.

We’re looking for our first dedicated marketing person: hands-on, generalist, willing to learn fast. You’d be working directly with the founder (one person, no committee, no politics), running day-to-day marketing execution across our products (we’re shipping consumer apps on iOS and MacOS)

This is a full-time, remote role (35–40 hrs/week). Initial 3-month engagement with strong intent to extend if it’s working. Could grow into a Marketing Lead role as the portfolio scales.

What you’d actually do:
Your time will shift between our products based on what’s live, what’s launching, and what needs the most attention. Expect 2–4 products active in your queue at any time. Across them:

- Basic SMM. Run TikTok, Instagram accounts for our apps. Mostly base for launching ads and influencers outreach. We give you the playbook.
- Creator outreach. Find influencers of small and medium size (1K–10K, 10K-100K followers) in each product’s niche. Reach out, send brief, pay them, collect content, track results. Markets vary — often US, Europe, Brazil, Japan.
- Community participation. Genuine presence in the Reddit / Discord / Telegram communities relevant to each product. Help people, build credibility, mention the app only when it actually helps the conversation. We do NOT spam.
- Newsletter sponsorships . Find small targeted newsletters per product, negotiate small ads.
- Reporting & systems. Weekly metrics sheet across all products (downloads, ratings, install sources, MRR). Weekly Friday written report across all projects.

Who you are:
Ambitious junior or self-taught marketer. The role demands real ownership. You’ll get a budget, a playbook, and weekly priorities — then you decide what to ship and when. We don’t want someone who needs daily approval to do the next obvious thing.

Required:
- Strong written English
- Active TikTok user — you get how it works in 2026
- Comfortable on Pinterest, Reddit, Instagram at user level
- Comfortable juggling 2–4 different products with different audiences and brand voices, without mixing them up
- Spreadsheets (Google Sheets), comfortable in Notion or similar
- Self-directed: weekly plan, ship, iterate, raise blockers early
- Honest about what works and what doesn’t

Would be a plus:
- Efficient with AI
- Personal interest in consumer tech and design
- Basic Canva or Figma
- Previous experience juggling multiple small clients or projects in parallel
- Familiarity with App Store Connect or app analytics tools

Not required:
- A marketing degree
- Years of experience
- Agency background
- Knowing “ASO” or “CAC” — we’ll teach what you need

How we work:
- Async-first. Daily Slack/ check-in, weekly call.
- Weekly Friday written update across all projects.
