We’re looking for a Social Media & Growth Marketing Specialist to join our small team and take responsibility for attracting new users to our app and growing our media presence.

This role combines social media management, content creation, influencer collaborations, and growth experiments. You’ll also become a public face of our brand, creating videos featuring yourself and our app.
 

What matters most to us is honesty, open communication, and proactivity. We’re looking for someone who takes initiative, is open about their weaknesses and knowledge gaps, and feels comfortable asking questions and seeking help in areas where they need support.

Previous professional experience is not required. We’re ready to teach you and support your development. However, you should already feel natural on camera and understand social media fundamentals, including hooks, content length, and how to communicate with an audience. You don’t need to speak on camera. We can use voiceovers or voices generated with AI instead.

What you’ll need:
 

English at C1 level or higher. You must be comfortable speaking freely in English, including holding conversations lasting one to two hours.

The first interview will be in English so we can assess your English level and how comfortably you express yourself in conversation. After that, everyday communication can be a mix of Ukrainian and English, with one weekly meeting with the founders held in English.

Confidence on camera. You should feel comfortable appearing in videos and presenting our app in a natural, engaging way. Speaking on camera is optional.
 

An understanding of social media content. You should understand what makes a strong hook, how to choose an appropriate content length, and how to adapt your communication to your audience.

You don’t need to know every tool or have experience with every responsibility below. We’ll help you learn what you’re missing.

Your responsibilities
 

Social media and community engagement

Manage and develop our presence on Threads, X (Twitter), Reddit, Discord, and LinkedIn.

On Threads, you’ll publish posts from our account, respond to replies on our posts, and engage with other creators’ posts by recommending and promoting our app in relevant conversations.
 

Instagram and TikTok content

Create weekly posts and stories for Instagram and TikTok. Produce carousels and reels including showcasing the app, from the initial idea through recording, editing, and publishing.
 

Influencer collaborations

Research potential influencer partners, evaluate opportunities, and make decisions about which collaborations to pursue.

Reach out to influencers, manage messages, follow up, and coordinate collaborations.
 

AI content and tools

Create videos using AI, experiment with cartoons generated with AI, and edit it.

Set up AI agents to support our marketing work and explore ways to use AI in content creation and daily workflows.
 

User acquisition and growth

Keep asking: “How can we get more users?” and “How can we increase our media presence?”

Bring ideas, identify opportunities, and turn them into practical experiments. Your role is not only to publish content, but also to help us understand what attracts people to the app.
 

Google Play and App Store pages

Manage and improve the text on our Google Play and App Store pages.

Experiment with different descriptions, using the testing options available on each platform. Track conversion rates for the different versions and use the results to identify the most effective messaging.
 

Reporting and teamwork

Create monthly performance reports covering our social media channels, Google Play, and the App Store. Summarize results, explain what worked and what didn’t, and suggest what to try next.

Participate in daily calls with the CEO and weekly calls with the whole team.

What we offer

• Base salary of $500+ per month, with salary reviews every few months.
• A performance bonus of $100 for every 1,000 new users.
• Equity/stock after three months of work.
• Learning support and access to experienced specialists. If you have knowledge gaps in marketing or other areas, we can pay for one or two consultations per month with more experienced specialists and purchase educational materials.
   

We don’t expect you to know everything from day one. We’re ready to teach you, help you develop your skills, and give you room to grow alongside the app.

Join an international engineering team building a high-performance data platform used by Fortune 500 companies. As a Middle Java Engineer, you’ll work with distributed, multithreaded systems, solve real-world production challenges, and deepen your expertise with mentorship from senior engineers. Fully remote across Europe, with long-term collaboration and the opportunity to grow in the data engineering domain.

About Our Client
Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.
 

About the Role
We are looking for a Middle Software Engineer (1.5–3.5 years of experience) to join the sustaining engineering team for the data catalog and enterprise data management layer of a large-scale lakehouse platform — the services that automate data ingestion and optimize Apache Iceberg tables for existing customers. The team's mandate is to keep these services running reliably for current clients: investigating and fixing customer-reported issues, resolving defects, addressing performance regressions, and keeping dependencies and security patches current. This is a maintenance and support role, not a feature-development role.
 

This is a backend Java role in a multithreaded, distributed environment where stability and availability for production customers are the baseline expectations. You will work with hands-on mentorship from senior engineers and in daily collaboration with US-based engineering leads and support teams.

Responsibilities
 

• Investigate, reproduce, and fix customer-reported issues and defects in the catalog and data-management services (Java)
• Diagnose production problems from logs, metrics, and thread or heap dumps, and work with support teams and solution architects on customer escalations
• Address performance regressions and stability issues in multithreaded, distributed services.
• Keep the services current: dependency and library upgrades, security patches, and compatibility fixes
• Write regression tests and small supportability improvements (logging, metrics, diagnostics) so issues are easier to catch and triage next time
• Take part in code reviews and follow the team's release and hotfix process
• Track and apply relevant upstream fixes from the Apache Foundation open-source projects used by the platform

• Communicate status, root causes, and blockers clearly in daily syncs with US-based engineering leads

• Comfortable debugging and supporting production systems — reading logs and stack traces, reproducing issues, and finding root causes
• Good grounding in data structures and algorithms
• Working knowledge of multithreaded and asynchronous programming in Java (java.util.concurrent, executors, futures) and the motivation to go deeper
• Care for engineering quality — tests, code reviews, and an understanding of why availability, resiliency, and zero-downtime upgrades matter 
• Comfort with a fast-moving environment, ownership of your work, and an eagerness to learn from and be mentored by senior teammates
• Comfortable with AI-assisted development workflows — using modern AI tools productively while critically validating their output
• English Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team

• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings
   

  Desired Skills

• C++ experience — reading or writing performance-sensitive native code
• Exposure to database internals or query planning
• Familiarity with distributed systems concepts: concurrency control, data replication, storage systems 
• Middle Software Engineer – Catalog, EDM
• Apache Iceberg or other open table formats (Delta Lake, Hudi)

• Messaging systems: Kafka, NATS, or cloud pub/sub servicesи Contributions to open-source projects (Apache projects especially valued)
   

  Details

• Engagement: Long-term contract
• Location: Europe (EU / EEA / UK), remote
• Working hours: EU business hours, shifted 2–3 hours later for daily overlap with the US West Coast team

ABOUT US

We are a US e-commerce company. We run the whole business on one internal web panel that we build ourselves: orders, customer support, call center, hiring, analytics, and ad production with AI video and image models. It is live and the team uses it every day.

THE ROLE

You will be the developer who owns this panel. The founder gives you the idea and a clear "done when". You plan it, build it with AI coding agents (Cursor), review what the agent wrote, test it, and ship it.

This is not a prompt-only job. The agent writes a lot of the code, but you are the one who reads the diff, finds the bug, and says no to a bad change.

STACK

• Next.js and TypeScript
• Supabase (PostgreSQL, SQL migrations)
• Vercel, Cloudflare R2
• A background job queue on a Linux VPS
• External AI APIs (video, image, LLM)

YOU ARE A GOOD FIT IF

• You have 3+ years of real web development with React or Next.js.
• You can write SQL and TypeScript by hand, without an AI tool.
• You use AI coding agents every day and you know where they fail.
• You can explain a technical problem in three simple sentences.
• You write clear English.
• You can work full-time for one company.

NOT A FIT

• Agencies and teams. We hire one person.
• People who can only prompt and cannot read the code.
• People with several other clients at the same time.

HIRING PROCESS

1. A 14-minute online test (code reading, multiple choice). We send you the link in chat right after you apply.
2. A 20-minute written test (a small function, one SQL query, three short answers).
3. A short live call with screen share.

We do not read CVs first. The test decides who moves on, and we reply to everyone who passes step 1.

Java · Selenide · AWS / Azure / GCP · Kubernetes · Terraform

Start here, and go deep

Upwind is a cloud security platform. Companies connect their AWS, Azure and GCP environments to us, and we tell them what's dangerous — vulnerable container images, misconfigured permissions, exposed identities, live attacks in progress.

It's a big product, and nobody arrives knowing it. You'll learn it with us — the cloud, the Kubernetes, the security domain, the automation. That's the deal: you bring the curiosity and the fundamentals, we teach you the rest.

What you'll be working on

Testing features by hand

• Learn a feature area properly, then write test plans for it — onboarding flows, dashboards, scanners, integrations
• Turn plans into clear, prioritized test cases with real steps and expected results
• Check new features against what product actually asked for, and verify fixes before they ship
• Run regression rounds before releases

Writing automation

• Write WebUI tests in Java + Selenide, in a framework that already exists — you'll be adding to it and learning the patterns, not building from zero
• Gradually automate the areas you've been testing manually, so your time moves to more interesting work
• Investigate failing tests: is it a real bug, or is the test unstable? Learn to tell the difference fast

Getting hands-on with cloud

• Set up your own test environments: connect AWS accounts using Terraform and CloudFormation, onboard Azure and GCP projects
• Deploy our sensors onto Kubernetes clusters and Linux servers
• Generate QA workloads and check the platform reacts the way it should
• Compare what the UI shows against the real underlying data — this is where the most interesting bugs hide

Reporting what you find

• Write bug reports engineers can pick up immediately: steps, expected vs actual, impact, environment, and evidence
• Learn to spot when five bugs are really one bug with one cause

What we need from you

• Some commercial QA experience — internship, junior role, or a year or two of manual testing
• Basic Java — you've written and debugged code, and you can read someone else's without panic. You don't need to be a developer.
• Some exposure to test automation. If you've written Selenium or Selenide tests in a course or a small project, that counts.
• Test design fundamentals: equivalence classes, boundary values, negative cases — the ISTQB material, understood rather than memorized
• Curiosity about how things work under the hood: you've opened browser devtools and looked at what requests a page makes
• Basic Linux comfort: you can SSH into a machine and read a log file
• Git and Jira
• English good enough to work in a distributed team every day

Genuinely optional

Cloud experience of any kind · Kubernetes · Terraform · a security course or CTF you did for fun · SQL · CI/CD

If you have none of these, that's fine. If you have one, tell us about it.

What we care about more than your CV

• You want to know why. "It's broken" is where you start, not where you stop.
• You'll set things up yourself rather than waiting for someone to hand you an environment.
• You write clearly. A vague bug report costs the team a day; a good one saves it.
• You want to learn cloud security properly. Not eventually. Now.

What you'll walk away with

Java automation experience in a real production suite. Hands-on AWS, Azure, GCP, Kubernetes and Terraform. A working understanding of how cloud attacks and defenses actually operate.

That combination takes most people years to assemble. You'll build it here, with people who'll teach you.

Bring the curiosity. Apply.

Why this role is worth your next few years

Most QA jobs teach you one product and one process. You learn the checklist, and two years later the checklist is still all you know.

This one is different. You'll work across cloud security on AWS, Azure and GCP — deploying Kubernetes clusters, running infrastructure-as-code, testing threat detection, and writing the Java automation that holds it together. That isn't one skill. It's the stack the entire market is hiring for, learned properly, alongside people who will actually teach you.

You'll start with support and a defined feature area. Within a few months you'll be running that area yourself.

What you'll be doing

Testing and test design

• Own test plans for your feature areas — onboarding flows, dashboards, scanners, integrations — and turn them into prioritized test cases with real exit criteria
• Run feature QA cycles: validate acceptance criteria against the PRD, verify each requirement, sign off before release
• Run regression sweeps and verify fixes before they move forward

Automation

• Write and maintain WebUI tests in Java + Selenide, extending a framework that's already there — you're not starting from a blank file, but you will be shaping it
• Automate the areas you test by hand, so your manual time goes to exploratory and new-feature work
• Keep the suite healthy: investigate failures, separate real defects from flakiness, and fix the flaky ones properly
• Start contributing to how we test, not just what we test — stable selectors, reusable helpers, better test data

Hands-on cloud work

• Set up your own environments: onboard AWS accounts via Terraform and CloudFormation, Azure tenants, GCP projects, and verify off-boarding actually cleans up
• Deploy our sensors on EKS with Helm and on EC2 hosts
• Generate QA workloads and confirm the platform detects and displays them correctly
• Cross-check the UI against the underlying data — where the most interesting bugs live

Working with people

• Daily contact with backend and frontend engineers, PMs and designers inside your feature squad
• Keep test plans, cases and results documented in Jira and Confluence so anyone can pick up where you left off

What you need to bring

• Commercial QA experience covering both manual and automated testing
• Java — enough to read, extend and debug an existing test codebase confidently
• Hands-on UI automation you've done on a real project (Selenide, Selenium, or similar — transferable experience is fine)
• Test design fundamentals, and the judgment to know what not to test
• REST APIs and browser devtools: enough to tell whether a bug is frontend, backend, or data
• Working knowledge of at least one major cloud provider — console, IAM basics, onboarding flows
• Basic Linux and CLI: SSH, systemctl, reading logs
• Git and Jira
• English for daily work with a distributed team

Nice to have — not required

Kubernetes basics · Terraform or CloudFormation · interest in cybersecurity (CVEs, CSPM, IAM) · SQL or OpenSearch · CI/CD · regulated environments like FedRAMP or SOC 2

What actually matters to us

• Curiosity about why something broke. The best bugs on our board come with a diagnosis attached.
• Ownership. You set up your own environments, chase the answer, and follow the fix through to verification.
• Precision in writing. A vague bug report costs the team a day; a good one saves it.
• Willingness to learn fast. You don't need to arrive a cloud security expert. You need to want to become one.

What you get out of it

Real mentorship from engineers who know this domain cold. Depth in cloud security across all three major providers, hands-on Kubernetes and infrastructure-as-code, and a mature Java automation stack.

You'll absorb in months what most people spend years collecting — and come out the other side as an engineer nobody wants to lose.

Curious? Apply.
