What We’re Looking For 

We are looking for a Senior PHP Developer who thinks in terms of architecture, ownership, and real production impact, not just task execution.

• English C1-C2 is a must

   

Strong Advantage

•  Experience with CMS/admin platforms
•  Experience with high-traffic content or affiliate websites
•  Experience improving old systems without full rewrites

Ownership & Product Mindset

You are a good fit if you:

• Think in terms of outcomes, not just tasks
• Challenge requirements when they are unclear, risky, or inefficient
• Understand how technical decisions impact performance, SEO, data quality, and business metrics
• Are comfortable being fully accountable for what goes to production
• Care about system behavior after release, not only about implementation

Not a Fit If

We are looking for a sharp, proactive, and experienced Middle Scraping Engineer to join our team and drive our web data extraction operations forward.

• Research, update, and develop custom unblocking solutions to bypass modern anti-bot protections;

What we expect
 

• Strong Python mastery ("Python Ninja") with clean, scalable code practices;
• Deep expertise in Scrapy, Playwright, and async networking;
• Solid hands-on experience with proxy management (residential, datacenter, rotating networks, session stickiness);
• Experience with advanced unblocking tools and techniques (bypassing Cloudflare, Akamai, Datadome, CAPTCHA solvers, TLS/browser fingerprinting);
• Practical DevOps knowledge (Docker, CI/CD pipelines, container orchestration, monitoring);
• Strong web reverse engineering skills (analyzing network traffic, API endpoints, WebSocket messages, minified JS);

• High level of responsibility, SLA-driven mindset, and target-oriented approach;
• Excellent teamwork, fast thinking, and strong problem-solving skills in high-pressure situations.

You’re gonna love it, and here’s why:
 

• Rich innovative software stack, freedom to choose the best suitable technologies;
• Remote-first ideology: freedom to operate from the home office or any suitable coworking;
• Flexible working hours (we start from 8 to 11 am) and no time tracking systems on;
• Regular performance and compensation reviews;
• Recurrent 1-1s and measurable OKRs;
• In-depth onboarding with a clear success track;
• Competera covers 70% of your training/course fee;

🌀 Malva is an early-stage B2B SaaS startup building a Sales Execution Platform that helps revenue teams improve sales execution, CRM discipline, and forecasting.

We help sales teams focus on the right deals, execute consistently every day, and eliminate the burden of manual CRM updates.

🔍 We’re looking for a B2B Content Marketing Specialist (LinkedIn & X) who will work closely with the founder and become an active part of the Malva team.

This is not a freelance, task-by-task role with scheduled posts. We need someone who can understand the product, our customers, and the sales problems we solve - and consistently turn that knowledge into content that creates qualified leads and conversations.

Your Main Goal

Use founder-led and company content to generate interest, conversations, and qualified leads among our primary US audience:

• Heads, VPs of Sales, Sales Directors and CROs;
• leaders of B2B sales teams with 5+ sales reps;
• companies using Salesforce or HubSpot.

Brand awareness and reach matter, but they are secondary to attracting the right audience and supporting customer acquisition.

Working Model

• Part-time: 4 hours every business day
• Consistent daily involvement rather than deadline-only freelance work
• Remote, hybrid, or office-based in Lviv
• 15-minute daily status sync

🎯 Growth Opportunity

Responsibilities

• Own the content strategy and calendar for the founder and Malva accounts on LinkedIn and X
• Create English text, visual, and video content from product updates, customer interviews, and founder ideas
• Produce demand-generation content for US B2B sales leaders using strong hooks, offers, lead magnets, and CTAs
• Adapt and distribute core ideas across platforms while engaging with the relevant audience
• Test content formats and track ICP engagement, inbound conversations, and qualified leads
• Stay up to date with B2B SaaS, AI, SalesTech, and startup trends

Expected Content Cadence

The weekly output will generally include:

• Founder LinkedIn: 3–4 posts
• Malva LinkedIn: 2 posts
• Founder X: 3–4 posts
• Malva X: 2 posts
• Video scripts according to the agreed content plan
  
  Requirements
• 3+ years of experience in B2B content marketing, founder-led content, or demand generation
• Proven ability to create content that generates qualified engagement, inbound conversations, or leads -not just reach
• Strong copywriting skills: hooks, positioning, offers, CTAs, and lead magnets
• Ability to turn ICP pain points, product value, and founder insights into compelling LinkedIn and X content
• Ability to simplify complex B2B SaaS ideas and write concise video scripts
• Strong written English and the ability to produce natural, publication-ready copy
• Proactive and reliable working style with thoughtful use of AI tools

Nice to Have

• Experience with B2B SaaS, SalesTech, CRM, RevOps, or GTM products
• Experience building founder brands
• Experience generating leads or sales conversations through organic content
• Experience creating downloadable guides, checklists, templates, or other lead magnets

Remote — must be based in Ukraine

ATAS is a professional platform for analyzing financial instruments and market data: footprint, DOM, cluster analysis, and order flow. The product is designed for active traders and is used in exchange-traded and cryptocurrency markets.

The commercial model is direct retail sales worldwide. Payments are made by card on a recurring subscription basis, with one-time licenses used less often. Registration is followed by a free trial and then recurring charges. Customers are located in North and Latin America, Europe, and Asia.

Payments are processed through three processors: Adyen, PayPal, and Medoro. Each has its own interface, reporting, and dispute-handling rules.
 

Why this role is needed

The company is growing, and the number of payment disputes is increasing along with turnover. This is expected in itself. But the volume has reached a point where it can no longer be handled on a residual basis.

There is currently no dedicated owner of the process, and the company does not yet have enough in-house experience to build it correctly. Some disputes are contested but not won, and we do not fully understand the reasons for the losses. There is no model that determines when it makes sense to fight a dispute and when it is cheaper to accept it. The processors’ risk tools require further configuration. The task is not limited to responding to disputes — a comprehensive approach is needed.

The role is to turn this into a manageable process: understand the causes, respond to disputes thoroughly and on time, collect evidence, track metrics, and feed information back into the product about what is causing disputes.
 

What you will be doing

• Handle disputes across all three processors. Review incoming cases, decide whether to contest them, prepare responses, and meet deadlines at every stage, including pre-arbitration and arbitration.
• Build the evidence base. Work with platform logs, account history, correspondence, session data, and device data. Understand what persuades an issuing bank and what does not.
• Analyze the causes. Regularly review processor exports and identify patterns by codes, geography, plans, timing, and transaction types.
• Find root causes in the product and eliminate them. A significant share of disputes is caused not by fraud, but by the way the product, billing, and communications are designed. Regularly go through customer journeys, identify problem areas, formulate tasks for development and support, and see them through to implementation.
• Track metrics. Calculate the dispute ratio and fraud metric for each processor, compare them with the thresholds set by payment schemes and the acquirer, and flag in advance when they are approaching those thresholds.
• Interact with processors. Correspond with support teams and account managers at Adyen, PayPal, and Medoro regarding risk-tool settings, available protection mechanisms, and payment-scheme rules.
• Develop protection tools. Evaluate and implement available mechanisms: automated dispute protection and dispute deflection
   

The first three months

The work starts not with responding to disputes, but with understanding where they come from. It makes no sense to analyze a claim without going through the customer journey yourself: you cannot defend something whose mechanics you do not understand.

• The first stage is an audit of the customer journey. Go through every scenario personally: registration, trial activation, plan purchase, renewal, plan change, subscription cancellation, and refund request. Identify points where customer expectations diverge from system behavior. Review checkout copy, notification emails, charge reminders, and the actual deliverability of those emails.
• In parallel, review existing disputes. Study exports from all three processors, compare customer claims with issues found in the customer journey, and separate conflicts caused by the product design from abuse.
• The second stage is legal documentation. Review the License Agreement, Regular Payments Offer, and refund policy for consistency with how the system actually works and for the applicability of their provisions in disputes with EU consumers. Some wording the company relies on in representations may turn out to be inapplicable.
• The third stage is the process itself. Establish dispute-handling procedures: prioritization rules, templates by claim type, deadlines by stage, pre-arbitration control, and monthly metrics reporting. By the end of the period, the process should operate without manual management from leadership.

The result of the first three months should be not only won disputes, but also a list of product changes with an estimate of how much each issue costs the company per year.
 

What we expect

Required:

• At least two years of experience with payment disputes — on the merchant side, at a payment provider, or with a specialized contractor.
• Understanding of Visa and Mastercard dispute rules: reason codes, dispute stages, deadlines, and evidence requirements.
• Ability to work with data: processor exports, pivot tables, and identifying patterns across a body of cases.
• Fluent English, primarily written. Representations to issuing banks, correspondence with processors, and work with payment-scheme rules are conducted only in English, and the quality of wording directly affects the outcome of a dispute.
• Experience with a subscription model. Conflicts around auto-renewals, cancellations, and refunds have their own specifics here, and without this experience it will be difficult to understand our disputes.
• Attention to detail. In this work, a mismatched date in an attachment or a reference to an inapplicable rule can invalidate the entire document.
• Familiarity with EU consumer law as it relates to digital content and distance contracts.
   

Nice to have:

• Experience auditing customer journeys or in product analytics — the ability to go through the buyer journey and identify where it breaks.
• Hands-on experience with Adyen.
• Experience with Verifi, Ethoca, RDR, or comparable dispute-deflection tools.
• Experience working with high-risk or dispute-heavy verticals
   

Terms

• Any work format: remote, hybrid, or office-based in Riga.
• Workload is negotiable — from part-time to full-time, depending on experience and willingness to take on adjacent payment-operations tasks. The workload is higher in the first months due to the audit and process setup.

We are looking for a Senior Full Stack Engineer with strong experience in VoIP, SIP telephony, and conversational AI to join a Healthcare product.
