• Працювати з community-management: відповіді в коментарях, DM, модерація

• Аналізувати engagement-метрики і коригувати стратегію — reach, saves, shares, follower growth, CTR з соцмереж

• Активно використовувати AI-інструменти для прискорення контент-продакшну — research, копірайт, генерація ідей, аналіз трендів

Що ми очікуємо

• 3+ роки досвіду в SMM, з фокусом на B2C-продукти

• Досвід ведення англомовних соцмереж на ринок США або інші Tier 1 ринки (UK, AU, CA)

• Сильний англомовний копірайт на рівні носія або near-native (Upper-Intermediate і вище з підтвердженим письмовим досвідом)

• Глибоке розуміння Instagram і TikTok — тренди, формати, attention economy, що працює на engagement у 2026

• Досвід роботи з контент-стратегією — від tone-of-voice до контент-плану на місяць

• Досвід паралельного ведення кількох брендів — вміння перемикатися між тон-голосами, не змішувати естетики

• Розуміння performance-креативів — як виглядає ефективний UA-креатив, чим він відрізняється від organic-контенту

• Активне використання AI-інструментів у щоденній роботі

• Базова аналітика — вміння читати дашборди Meta Business Suite, TikTok Analytics, GA4

• Ownership-mindset: бачиш можливість росту — пропонуєш гіпотезу, не чекаєш інструкції

Буде плюсом

• Досвід ведення блогів та SEO-контенту

• Досвід роботи з community у Reddit 

• Досвід influencer-співпраць на ринок США

• Свобода у виборі AI-стеку та підходів — ми вкладаємось у tooling

• Remote-first культура з гнучким графіком

PaperLink (paperlink.online) solves a simple problem: you send a client a document and have no idea if they even opened it. PaperLink shows who opened it, when, which pages they read, and how long they spent on each. Plus invoicing, financial tracking, and AI integration with Claude via MCP.

The product is live, works, and has real users. Competitors like DocSend charge $45-150/month. We have a free plan. No competitor has MCP-based AI integration. There's something to sell and people to sell it to.

What's missing: someone focused on customer acquisition. We're strong at building, not selling. That's why we're looking for a partner.

What you'll do

Find people who need PaperLink and get them to try it.

Specifically:

• Outreach through professional networks, communities, and Q&A platforms
• Build partnerships with bloggers and review authors in the document sharing niche
• Support affiliate program development
• Track what works, what doesn't, and where to focus next

Who we're looking for

Someone with four qualities:
Outreach or community experience. You've found clients online, engaged with potential users, or built a product presence in professional communities. Even on a small scale counts.

Ability to sell without "selling". No spam, no mass blasts, no aggressive pitches. Just helpful answers, honest recommendations, real conversations.

Independence. We provide context, tools, and feedback. You decide what to work on each day.

Results-driven. You see this as a chance to grow with the product, not just log hours.

Bonus: SaaS or B2B experience, SEO knowledge, affiliate marketing background.

Not required: marketing degree, Google Ads certifications, big company experience.

Compensation

Stage 1 (first ~10 paying clients): 50% commission from payments of clients you bring, for 12 months. Example: 10 clients at $100/month average = $500/month for you. Paid monthly or as a lump sum depending on the client's plan.

Stage 2 (after 10 paying clients, ~2-4 months with active work): fixed rate + 50% commission stays. Rate discussed individually based on experience and market.

Stage 3 (stable MRR): full salary + commission. Agreed upfront, not "maybe someday."

Payments: monthly, method by agreement.

Why this might interest you

The product exists. This isn't an idea-stage startup. The platform works, has users, and features comparable to tools charging $45-150/month.

The market is large. Every freelancer, lawyer, and consultant sends documents to clients. DocSend serves tens of thousands of companies.

The advantage is real. MCP-based AI integration, 6 interface languages including Greek and Arabic, invoicing and finance in one product.

Part-time friendly. You can combine this with other work or projects.

What not to expect

Fixed salary from day one. You start on commission and move to a fixed rate after 2-4 months upon hitting KPIs. If you need immediate stability, this isn't the right position.

Passive income. This requires active daily work.

A big team or mentorship. We work closely together. We provide context and product support, but there's no micromanagement.

Format

Remote. Flexible schedule. Any time zone.

About the Role:

You will be joining a team building a secure, privacy-focused communication platform designed for organisations where data protection, control, and regulatory compliance are mission critical. The product provides encrypted messaging, voice, and video communication built on a zero-trust security architecture with strong end-to-end encryption. It supports flexible deployment models — including on-premise and controlled cloud environments — and is used by security-sensitive and regulated organisations to protect confidential communications and maintain full data sovereignty.

As a QA Automation Engineer, you will be responsible for building and maintaining automated test coverage across iOS and Android, ensuring the reliability and integrity of features where quality is not just a standard — it is a compliance requirement.

What You Will Work On:

• Designing, writing, and maintaining automated test suites for iOS and Android mobile applications using Appium and Java;
• Covering encrypted messaging, voice/video calling, file sharing, and meeting features with automated scenarios;
• Developing and maintaining test frameworks and reporting pipelines with TestNG and Allure;
• Integrating automated tests into CI/CD workflows via GitLab pipelines;
• Managing test cases and documentation in Testiny; tracking defects in Jira;
• Collaborating with developers and product managers throughout the full QA cycle;
• Leveraging Claude for AI-assisted test generation and QA workflow optimization.

Required Skills:

• 1+ years of QA automation experience with a strong focus on mobile testing (iOS and Android);
• Solid hands-on experience with Appium for mobile test automation;
• Proficiency in Java for writing and maintaining automated test scripts;
• Experience with TestNG as a test framework;
• Allure for test reporting and result visualization;
• Jira for bug tracking and task management;
• Testiny for test case management;
• GitLab - CI/CD pipelines, MR workflows, test integration;
• Claude - AI-assisted tooling in QA workflows;
• English level: Intermediate+ or higher (written and spoken).

Nice to Have:

• Experience testing security-sensitive, privacy-focused, or compliance-driven products (HIPAA, GDPR, ISO 27001, etc.);
• Familiarity with zero-trust security concepts or end-to-end encryption;
• Experience testing real-time communication features: VoIP, video calls, WebRTC;
• Basic API automation skills (REST Assured or similar);
• Understanding of cross-device and cross-platform compatibility testing strategies.

Tech Stack:

Appium · Java · TestNG · Allure · Jira · Testiny · GitLab · Claude

We are a team in the iGaming industry. Our goal for this year is to launch and scale our own SEO department, focusing on creating and developing a network of content projects and satellites across international markets.

This position is for someone who has outgrown the role of a regular Senior Specialist and is looking for complete freedom of action. We do not offer a seat in a rigid corporate system filled with endless approvals and micromanagement. We are looking for an individual who will build processes from scratch, assemble a team, and head a fully-fledged SEO department.

Important: We are ready to consider strong candidates from classic e-commerce, B2B, large-scale content projects, or media. If you know how to handle high data volumes, process automation, and link building, but haven't worked in iGaming yet, we will help you get up to speed with the vertical's specifics quickly.

## What We Offer (Your Freedom Zone):

* Carte blanche on decisions: You choose the tech stack, software, contractors, and internal SEO strategy to achieve KPIs.

* Building a department: An opportunity to hire link builders, developers, and content managers to meet your goals.

* Zero bureaucracy: Direct dialogue with the project investor/owner. Fast budget allocation for necessary software and website promotion.

* Top-tier conditions: A stable fixed salary (discussed individually based on the interview results) + KPI bonuses. Paid in USDT.

What You Will Do:

* Develop and implement a comprehensive strategy for rolling out and promoting a network of websites from scratch.

* Build an efficient content creation pipeline (implementing automation tools, AI prompting, and setting up localization workflows).

* Fully manage the department's link building strategy: from link profile quality control to finding new high-authority backlink sources.

* Hire, onboard, and coordinate your team.

What We Look For in a Candidate:

* 2–4 years of SEO experience in a Senior or Team Lead position.

* Deep understanding of technical SEO: scaling project networks, backlink profile management, and routine process automation.

* Proficiency with standard analytical software (Ahrefs, Screaming Frog, trackers, anti-detect browsers).

* Experience managing promotion and link building budgets, as well as evaluating their ROI.

* Prior experience in iGaming is a plus, but a systematic product mindset and the ability to build processes are our top priorities.

About the Client Our client is an expert-powered AI companion platform. They help leading experts in their fields turn their voice, perspective, and body of work into an interactive AI twin their audience can talk to, any time. Personal, practical, scalable. A relationship, not a feed. A companion, not another app.

The Role They need a Senior Flutter Developer who will own their mobile product end to end. This is not a ticket-taker role. You will be the technical authority on their iOS and Android apps, making architectural decisions, setting standards, and driving the mobile roadmap from planning through to production.

You will define how they build mobile, not just for today's team, but for the team they are scaling into. That means auditing what exists, establishing the architecture and standards the next five engineers will work within, and making them faster as they grow, not slower.
 

Core Responsibilities

Technical Leadership. Own the mobile architecture. Make and document decisions on state management, navigation patterns, module structure, and platform integration strategy. You set the direction, you do not wait for it.

Project Ownership. Drive the mobile roadmap alongside product and design. Scope work, flag risks early, and deliver without needing to be managed.

Architecture Audit. Assess the current mobile codebase, identify structural weaknesses and technical debt, and build a clear roadmap to a more robust, scalable architecture.

Native Bridge Expertise. You do not just use packages. You modify them. You dive into Swift and Kotlin to fix what Flutter cannot.

System-Level Awareness. iOS and Android app lifecycles, background execution limits, memory management, and threading.

Code Quality and Standards. Establish and enforce coding standards, review architecture and PRs, and ensure the codebase stays maintainable as the team grows.

Team Building. Define how the mobile team works: sprint cadences, PR review standards, branch strategy, release processes, and how new engineers are onboarded.

Cross-Functional Guidance. Partner with product, AI, and backend teams to ensure mobile architecture is designed for features coming, not just features shipped.

UI Precision. Pixel-perfect interfaces that respect device-level realities.

Performance. Identify and eliminate memory leaks, jank, and bottlenecks.

Security. Handle platform-specific behaviours including permissions, notifications, and secure storage.
 

Required Technical Skills

• 5+ years of Flutter in production
• Track record of leading a mobile project or team. You have been the person responsible for mobile output, not just a contributor
• Real-time communication integration: WebSockets, WebRTC, or LiveKit (or equivalent voice/video streaming SDKs)
• Audio and video playback/streaming on mobile
• Experience integrating AI/LLM-driven features on the client side
• Deep command of Dart: async programming, isolates, and streams
• Scale: proven experience handling apps with 100k+ concurrent sessions or viral spikes
• CI/CD: Fastlane, GitHub Actions, or Bitrise for automated mobile pipelines
• Experience hiring or growing a mobile engineering team (even 2 to 3 people)
• Communication: able to articulate technical trade-offs to non-technical stakeholders and push back constructively
   

We’re launching a new division within our company focused on mobile app development and user acquisition. Our first product is an iOS cleaner app, and we’re already scaling traffic through Google and Facebook. Now, we’re looking for a User Acquisition Manager to fully own our marketing strategy and drive profitable growth.

What You’ll Do:

• Fully manage and scale user acquisition campaigns on Facebook and Google, with a focus on the US market
• Work independently to plan, execute, and optimize campaigns for iOS utility apps (iOS cleaners, VPNs, etc.)
• Analyze performance data to ensure high ROI and efficient budget allocation
• Develop, test, and iterate on creative strategies and funnels to improve performance
• Continuously conduct competitor research to identify trends and opportunities
• Lead and refine web-to-app flows to improve user acquisition metrics

• Deliver consistent, positive results while maintaining cost-efficiency.

   

What We’re Looking For:

• Proven experience managing user acquisition for mobile apps, especially in the utilities category (e.g. iOS cleaners, VPNs)
• Strong hands-on expertise with Google Ads and Facebook Ads platforms
• Experience with scaling campaigns in the US market
• Deep understanding of mobile analytics, conversion tracking, and campaign optimization
• Experience with web-to-app user acquisition flows
• Highly analytical, results-driven, and self-motivated

• Ability to work autonomously, take ownership, and drive profitable campaigns.

   

What We Offer:

• A chance to shape a new product and drive its success from the ground up
• Full ownership of user acquisition strategy
• Competitive compensation with performance-based bonuses
• Flexible remote work environment
• A highly motivated team and fast decision-making process.

We take products from zero to hero, and scale them until they’re strong enough to be handed over to core teams. No legacy constraints. No endless support cycles. Just greenfield builds, modern tech, and real ownership from day one.

We move fast, think lean, and execute with focus, one product at a time, full commitment, full impact. Every sprint matter, every decision ship value. This is not a support team. It’s a build-from-scratch engine for products that matter, because every hero needs a superhero.
