Your Role:

You will have a key role in our rapidly growing, fast-paced organisation. The ideal candidate will be responsible for helping our software development perform manual testing of our web-based product. You will work with our CTO and automation engineers to document and create test cases, and then run them.  We’re looking for a self-starter with experience in QA, a knack for breaking things, finding bugs and problem solving them.

Benefits:

Work from home, flexible hours

Be a key member of a small team

Fast paced startup environment, global team

Get things done while having fun

Help real people succeed in business

Get rewards and bonuses for working hard

Compensation in USD

Unlimited days off

Responsibilities:

Own the manual testing process for our web-based lending platform, from reviewing requirements through to release sign-off

Write clear, comprehensive test plans, test cases and checklists based on user stories and acceptance criteria

Execute functional, regression, smoke and exploratory testing across browsers and mobile web

Use AI assistants (Claude, ChatGPT, Copilot and similar) to draft and expand test cases, generate test data and speed up bug reproduction, then apply your own judgement to verify what the AI produces

Validate data end to end, including API responses (Postman or similar) and database checks with basic SQL

Identify, reproduce, document and track defects in Jira with clear steps, evidence and severity

Perform thorough regression testing before each release and keep the regression suite current

Contribute to QA process improvement: test coverage, test data, environments and release checklists

Previous experience with international or US-based teams

How We Use AI Here:

AI is part of how we work, not a replacement for thinking. You will be encouraged to use AI tools to move faster - drafting test cases, generating realistic test data, summarising regression results and exploring edge cases you might otherwise miss.

What we expect in return is accountability for the result: verify what the model gives you, keep customer and company data out of public tools, and tell us when AI is not the right tool for the job.

If you have not used AI much in QA yet but are curious and quick to learn, that is fine - we will help you get there.

Hiring Process:

Intro call, a short practical QA exercise based on a real scenario from our product, a technical interview with our CTO and a pre-employment assessment. We aim to keep the whole process inside two weeks.

Environment and Culture:

We work hard, days can be long, but we get rewarded for it

We are driving for growth

We are available and responsive

We think ahead, but we get things done quickly

We move fast, but try not to break things

We are hiring on behalf of our client — an American media company with an office in Warsaw. They own and monetize a large newsletter portfolio across finance, health, and business verticals, sending to millions of subscribers in the US. SMS is their next major revenue channel, and nothing exists yet. This role builds it from scratch.
 

The role

This is a full ownership role for someone who has launched SMS programs at scale and knows how to turn a subscriber list into a revenue line. You will design the infrastructure, build the opt-in strategy, own the monetization, run the content operations, and hire a team as the channel grows.

You will not be inheriting an existing program. You will not be coordinating vendors. You will be the person who decides how this is done and executes it directly, with full access to leadership and real resources behind you.
 

What you will own

• SMS infrastructure: platform, vendor ecosystem, sending architecture, segmentation, and message routing
• Opt-in strategy and subscriber growth across newsletter properties, web, and email
• Deliverability, sender reputation, and performance metrics
• Full subscriber lifecycle from opt-in through churn
• SMS content calendar, copy standards, and editorial coordination
• SMS advertising product: rate card, inventory, targeting, advertiser reporting
• TCPA, GDPR, and carrier compliance end to end
• Team building as the channel scales
   

Must-have

• 5+ years in SMS marketing or mobile messaging, at least 2 at high-volume scale
• Proven track record launching an SMS program from scratch — not inheriting an existing channel
• Hands-on experience with a major SMS platform: Klaviyo, Attentive, Postscript, Twilio, or comparable
• Experience building and selling SMS advertising inventory: rate cards, targeting, advertiser reporting
• Deep compliance fluency: TCPA, GDPR, CTIA — lived and enforced, not listed
• Experience hiring and managing a small team
• Data-driven: tracks everything, reports clearly, decides from numbers
• C1+ English, written and verbal
   

Nice to have

• Background in newsletter, media, affiliate, or performance marketing
• Experience with workflow automation tools: Make, Zapier, or similar applied to messaging ops
• Familiarity with A/B testing applied to copy, send timing, and opt-in conversion
• Technical fluency with APIs, webhooks, or basic scripting for platform integrations
   

Compensation and benefits

• Competitive salary + bonuses
• 21 paid vacation days, 15 paid sick days
• Remote or hybrid, Warsaw office
• B2B contract, company covers taxes
