EducateMe is an AI-native learning platform for growing US companies. We're hiring a growth operator to own a new acquisition channel: AI search.

You'll be measured on the number of SQL, not articles.

When a buyer asks ChatGPT, "what's the best LMS for a 200-person behavioral health company?" — your job is to make sure EducateMe is in the answer. That's the whole role: owning how AI assistants see, describe, and recommend us.

This is not a content manager position. Content production is ~30% of the job, and even that part is operating our AI content engine (Claude-based pipeline): prompting, editing, injecting real customer specifics, shipping. Nobody here writes articles from scratch since we operate the AI-powered content engine

What you'll own:

The channel and its number. Your KPI is AI-attributed demos/month, with citation share on our target prompt set as the leading indicator.

1. On-site assets — run the AI content engine: comparison and alternative pages, pricing content, question pages, case studies. You maintain the money pages that AI assistants cite.
2. Off-site presence — manage the Reddit agency relationship, pitch industry listicles (eLearning Industry and similar), own our G2/Capterra profiles and the review pipeline (with our CSM), keep the YouTube listing-video cadence running.
3. Measurement — monthly money-prompt tracking across ChatGPT, Claude, Perplexity, and Google AI Mode; demo attribution analysis; a monthly "what moved and why" readout to the founder.
4. Sales enablement spillover — case studies, one-pagers, and snippets flowing to our outbound SDR and founder-led deals. The same assets serve both.

Requirements

• AI-native. Daily user of ChatGPT/Claude — you have an intuition for how AI assistants compose answers and pick what to recommend.
• Channel ownership experience. You've run a growth channel to a measurable result: traffic, leads, revenue. Any channel counts, including your own project (a site, a community, a Telegram channel you grew).
• Data-comfortable. You read analytics without hand-holding and find answers in data yourself.
• Strong written English (C1). Editing and judgment matter more than prose.
• Generalist mindset. Content, community, and measurement in one role: you switch between them daily.
• B2B SaaS experience is a plus, not a must.
   

What this role is NOT:

• Not a classic content manager or copywriter — we don't need article volume
• Not classic SEO — link building and keyword rankings aren't the game
• Not an agency strategist — no strategy decks, hands-on execution only

Format

• Full-time, remote
• You report directly to the founder and work alongside a small senior team (product, engineering, customer success, outbound)

About the role:

We’re looking for a Customer Support Specialist to be the first point of contact for our customers on a Salesforce-native SaaS platform. This role is about ownership: you take a ticket, you own it until it’s resolved.

This is not a software engineering role, but you’re expected to navigate the product deeply enough to solve problems independently, and know when and how to escalate with context, not just a forwarded ticket.

This is a remote position for the US market. Availability is expected between 9am and 6pm Central US time.

Responsibilities:

• Own customer support end-to-end through chat, email, and video calls from first response to resolution.
• Run onboarding sessions for new users.
• Independently troubleshoot and resolve issues before escalating; when escalation is needed, create a clear, well-documented task with context and a proposed direction.
• Maintain and improve the knowledge base and help center so recurring issues get solved faster.
• Spot patterns across tickets and flag them to product/engineering proactively — not just react one ticket at a time.

You will succeed in this role if you have:

• Fluent spoken and written English (customer-facing role) C1 or above.
• At least 3 years of experience in a Customer Support role.
• A proven example of resolving a customer problem independently without waiting for instructions, and the ability to explain your approach and the outcome.
• Experience in retail, e-commerce, or SaaS product support.
• Experience communicating with both non-technical customers and technical teams.
• Ability to navigate Salesforce confidently as an end user (opening records, locating fields, understanding the basic data structure). Administration experience is not required.
• Desire to be part of a small, fast-moving startup team.

Nice to have:

• Experience with Intercom, Zendesk, Freshdesk, or similar support platforms.
• Experience with Salesforce administration (users, roles, permission sets, basic configuration).
• Background in customer success or onboarding.
• Basic understanding of how integrations/APIs work enough to tell an integration issue from a UI side.
• Familiarity with CRM/ERP/POS systems (conceptual level).

What success looks like:

• Customers get resolutions, not just responses.
• Escalations to the team come pre-investigated, with context and a proposed solution.
• You proactively surface product issues before they become a pattern of complaints.
• The team trusts that if it’s in your queue, it’s handled.

What’s in it for you:

• 15 days of paid vacation per year.
• US Federal Holidays (11 days).
• 10 sick days per year (5 with medical certificate + 5 without).
• Remote-first — full flexibility on location.
• Direct mentorship from founders.
• Your voice matters — direct input into product decisions, not just ticket-routing.

If you’re the kind of person who loves figuring things out, takes ownership, and believes every ticket deserves a real resolution — we’d love to hear from you.

We're a creative agency looking for an AI-native builder to be our go-to for anything that can be built or automated with AI. We work project by project, and we move fast. If you can build in days what used to take weeks, that speed is exactly what we're paying for.
 

What you'd work on

It changes weekly: a custom site for us, an app one of us is building, a membership portal or rewards program, an internal automation that saves hours, or something we haven't thought of. If it can be built intelligently, it lands with you. We want someone energized by that range, not thrown by it.
 

Who we're looking for

• You live in AI tools (Claude Code, Cursor, whatever you've made your own) and have real opinions about them.
• You know where AI fails. Generating a prototype is easy now; knowing when the output is wrong, insecure, or won't survive real use is the actual skill. That's what we're paying for.
• You design as well as build, or at least have a real eye. We give brand direction and references; you make it real.
• You've shipped things people use, ideally maintained something past launch.
• You think like an owner, not a contractor counting hours. You'd rather solve it than pad it.
• You're comfortable with ambiguity: landing page one day, automation the next, internal tool after that.
   

On tools: you'll know your stack better than we do. Shopify, Webflow, WordPress, custom, whatever fits the job. We care that you pick right and execute well, not that you know one platform. Automation and app experience (n8n, Make, backends) is a plus.
 

How this works

Your first project is real, a website build we already have scoped, so you're producing from day one, not interviewing in the abstract. It's paid like any other project, and if it goes well there's ongoing work from there.
 

Compensation: $700 to $2,000 per project depending on scope, experience, and speed. Website builds fall in that range; larger apps, portals, or automation work are scoped and quoted separately. Open on location and hours as long as output is strong and communication is reliable.
 

To apply, send:

1. Live links to things you've built. Not screenshots.
2. A few sentences on a time AI got you 80% there, and what you did for the last 20%.
3. One thing you automated or built that saved real time.

That second answer tells us more than any portfolio.

How you’ll make an impact (position summary)

Miaplaza is dedicated to making education engaging and accessible through innovative online learning platforms. We develop personalized learning experiences for students, helping them grow in a supportive and interactive environment. Our vision is to elevate online learning by applying the most successful approaches in virtual education to create an accessible and inclusive education curriculum platform where all students can be successful!

The Role

We're looking for a QA Engineer to join our current QA team. You'll take ownership of how we test, validate, and sign off on quality across our platform. We're actively investing in our QA practice: expanding automated test coverage, improving our release testing process, and moving toward a model where quality is embedded throughout the development lifecycle.

You'll report to a technical Engineering Manager and work alongside engineers who value clear test documentation, reliable automation, and confident code releases.

As a mature company, we have legacy systems and established manual testing workflows, but we are transitioning to modern automated testing practices using Playwright and TypeScript. The split between manual and automated work varies, but you should be comfortable working across both, bringing automation where it adds the most value while pragmatically maintaining manual coverage where it's still the right tool.

A core goal of our QA evolution is to make testing faster, more reliable, and less dependent on last-minute changes before each release: replacing fragile manual regression cycles with stable automated suites, reducing flakiness, and building coverage that the whole team can rely on. Every testing investment is measured by whether it improves quality and reduces the team's burden at release time.

What We're Looking For

What you'll do:

• Write and maintain automated regression tests; review automation MRs from peers
• Execute manual testing across web UIs (functional, regression, cross-platform, responsive layouts on mobile/tablet)
• Create and maintain test cases, checklists, and test documentation in TestRail
• File clear, actionable bug reports with reproduction steps; collaborate with developers to triage and resolve
• Own the release testing process to ensure only high-quality changes ship
• Partner with PMs and designers on requirements review, edge cases, and acceptance criteria
• Contribute to QA process improvements as we scale (currently a 2-person team growing to 4)

Requirements (Requisite Skills): 

• 2+ years of QA engineering experience, including web UI testing
• 2+ years of experience with Playwright or a similar test automation framework (e.g. Cypress, Selenium, Puppeteer)
• 2+ years of experience using TypeScript
• Strong test design skills: comfortable writing and maintaining test cases, checklists, and test documentation
• Familiarity with QA's role in the SDLC and how to collaborate with developers and PMs
• Strong analytical skills and attention to detail
• Strong experience in manual testing and writing manual test cases
• Upper-intermediate English (B2+) for written and spoken communication
• Nice to have: experience with accessibility or security testing

How you’ll work with other teams:

Stakeholders & How you’ll collaborate with them

Developers

Notify developers of issues found during the testing phase, providing clear reproduction steps and screenshots. Collaborate to determine whether each issue is a true bug, expected behavior, or an environmental problem. Developers support QA by providing hotfixes and a dedicated testing branch with a restored database.

Product Managers

Provide clear evidence and detailed descriptions of issues so the Product Manager can assess their severity and user impact to determine whether they are release blockers. Discuss edge cases and user flows not covered in the ticket description or acceptance criteria, and document the expected behavior. Highlight risks in delivery ( too many critical issues found during the testing phase, potential ticket revert).

Engineering Manager

Your direct manager. Conduct regular 1:1s with you, provide development and tooling support, collaborate on problem-solving, monitor QA team progress, and review your work output.

Career Growth

We have a defined career ladder. Whether your path leads toward Senior/Staff QA Engineer or Engineering Management, there's room to grow - and we'll work with you to get there.

Onboarding

Every team member gets full support throughout onboarding, and no one expects you to figure out the ins and outs on your own. We'll pair with you, answer every question, and make sure you have the context you need. New hires typically feel very supported at Miaplaza.

What success looks like here: In the first couple of months, you're asking a lot of clarifying questions, reading documentation, exploring the product independently, and writing and running tests with confidence. By months 3-4, you're taking ownership of a specific area, building out test coverage, identifying gaps, and driving quality improvements. By months 5-6, you're contributing meaningfully to the testing strategy for migration and modernization work and operating independently. The common thread: curiosity, initiative, and the habit of investigating before you ask, but always asking when you need to.

Interview Process

Our process is staged and designed to respect your time. Expect a mix of introductory conversation, technical discussion, and practical evaluation. We want to understand how you think about real problems and testing practices. As part of the process, we will ask for professional references and conduct a background check. If you need any accommodations during the interview process, let us know, we're happy to help.

Compensation

Miaplaza’s compensation philosophy ensures equity and competitiveness while considering regional differences in labor costs. Placement within a range is determined based on factors such as demonstrated skills, internal equity, and local labor market rates for the candidate’s geographic area.

Why we exist:

Swarmer develops software that makes drones autonomous and allows them to operate together, in large, coordinated teams — no pilots needed. Our technology has been battle-tested in Ukraine— the world’s most intense proving ground for drone warfare. 

In March 2026, we became the first Ukrainian defense startup to go public on NASDAQ, following a $15M Series A — the largest investment in a Ukrainian defense tech company since the start of the war. 

Working at Swarmer means operating at the intersection of engineering rigor and frontline reality. The problems and environments are complex, and the stakes are very real. We built this software to enable democratic nations to defend themselves.  

If you are motivated by building resilient systems that matter and by seeing the direct impact of your work, you’ll find purpose here.

What we’re looking for:

We are looking for an experienced Cybersecurity Engineer(Endpoint & Identity) to join our team. The role is focused on corporate IT infrastructure, not product infrastructure. Your day-to-day work will be related to laptops, software, SaaS, and user accounts security. Therefore, your peers will be the IT team members, collaborating closely with our DevOps engineers on shared areas of responsibility.

This hands-on engineering role requires a strong foundation in MDM, IAM, and networking. You will harden laptops, BYOD, SaaS, LANs, and cloud, and use MDM and IdP solutions to maintain the security standards of our infrastructure. Your work will be guided by established industry frameworks and aligned with security best practices.

What you’ll do:

• Maintain hardening and configuration baselines for endpoints and servers (encryption, security policies, benchmarks).
• Deploy and manage endpoint and server protection across the fleet (EDR/NGAV, antivirus, device management), including security policy enforcement and compliance configuration.
• Administer network security controls (firewalls, VPN, network segmentation, access controls) and monitor traffic for suspicious activity.
• Review infrastructure projects and architecture from a security perspective to ensure secure-by-default configurations.
• Run regular vulnerability scans across endpoints, servers, and cloud, with risk-based prioritization and remediation tracking.
• Enforce identity and access best practices (role-based access, least privilege, MFA, privileged access management) and run periodic access reviews.
• Monitor and analyze security events and logs to detect anomalies and potential threats.
• Detect, investigate, contain, and remediate security incidents, including documenting timelines, root causes, and lessons learned.
• Monitor cloud and SaaS security posture, remediate misconfigurations, and review third-party integrations and access scopes.
• Implement and document technical security controls (runbooks, hardening guides) and support internal and external audits.

What we need:

• 5+ years of hands-on experience in IT infrastructure or cybersecurity engineering with a clear security specialization.
• Hands-on experience administering and hardening Linux, Windows, and macOS systems using MDM solutions
• Experience with endpoint protection and device management platforms (EDR/NGAV, MDM, antivirus).
• Solid understanding of networking fundamentals (TCP/IP, DNS, DHCP, VPN) and practical experience with firewalls and network security controls.
• Hands-on experience with identity and access management / SSO platforms with a security-first approach.
• Experience with vulnerability management tools and SIEM/SOC monitoring and incident-response workflows.
• Understanding of common attack types and detection/prevention methods.
• Practical familiarity with recognized security frameworks and standards.
• Analytical mindset with the ability to assess risk and prioritize pragmatically.
• Clear communicator able to explain technical issues to non-technical colleagues.
• English proficiency (documentation, vendors, and external partners).

Would be an advantage:

• Ability to automate security and infrastructure tasks with scripting (Python, Bash, or PowerShell).
• Working knowledge of cloud security controls.
• Security certifications.
• Experience in enterprise or critical-infrastructure environments.

What you’ll get:

• Direct impact: your work protects systems that operate in real, high-stakes environments.
• Competitive salary, benefits package (insurance, paid sick leaves, 20 paid days off per year).
• Benefits of the defense sector (reservation, etc).
• A straightforward, no-bureaucracy culture.
