Full job description

MyHealthAngel is a performance marketing and insurance distribution company. We run paid- media campaigns that generate inbound insurance calls and leads across Medicare Advantage, Final Expense, Hospital Indemnity, Auto, and other verticals, and sell those calls to carriers, agencies, and call buyers on a pay-per-call and CPA basis. We also operate a licensed insurance agency and a direct-to-consumer subscription product.

Our finance operation is heavily automated: invoices are generated from call-tracking data, and AI agents produce daily P&L, revenue, and reconciliation reports. We are looking for a Controller who will own the numbers, set the rules our systems follow, and keep our books accurate, well-controlled, and ready for investor or lender review.

This is a high-ownership role, not a data-entry position. You will report directly to the owners and manage our Billing & AR Specialist.

Responsibilities:

• Lead the accounting function and manage the Billing & AR Specialist; maintain a documented close calendar and SOPs
• Own the general ledger, chart of accounts, classes, and products in QuickBooks Online

• Prepare monthly P&L, balance sheet, and cash-flow statements, plus segment reporting by business unit and vertical
• Keep the media/lead-generation business, insurance agency, and subscription business clearly separated in the books
• Review and approve weekly, semi-monthly, and monthly invoice runs generated from Ringba call-tracking data
• Manage month-end cutoffs, including billing weeks that cross month-end
• Reconcile billable calls and revenue against buyer platforms (CallGrid, Retreaver, Everflow) and client CPA sheets; resolve disputes
• Own collections, AR aging, credit terms, and cash application; report cash collected separately from revenue invoiced
• Oversee AP for media spend (Meta, Google/YouTube, native, programmatic), telecom, vendors, and contractors
• Calculate and control tiered media-buyer profit-share payouts
• Record carrier commission revenue, including chargebacks and clawbacks, and account for Stripe subscription revenue and deferrals
• Design and enforce internal controls: segregation of duties, approval authority, dual authorization, role-based system access
• Build and maintain a rolling 13-week cash forecast and manage working capital
• Deliver profitability analysis by client, vertical, media channel, and business unit, and flag unprofitable relationships early
• Act as finance owner of automated workflows: define business rules, review exceptions, and approve changes before production
• Coordinate with our US-based CPA and tax advisors on tax filings, 1099s, audits, and quality- of-earnings work

Requirements:

• 5+ years of progressive accounting experience, including 2+ years as Controller, Assistant Controller, or Accounting Manager
• Bachelor’s degree in Accounting, Finance, or a related field
• Experience keeping books for US companies under US GAAP, including US-style month-end close
• Fluent professional English, written and spoken
• Availability for at least 4 hours of overlap with US Eastern Time (4:00–8:00 p.m. in most of Eastern Europe), with extra availability during billing cycles and close
• Experience managing at least one accounting or billing team member
• Advanced QuickBooks Online skills (classes, products, journal entries, reconciliations, reporting)
• Advanced Excel or Google Sheets skills
• Hands-on experience designing and enforcing internal controls
• Proven ability to reconcile high transaction volumes across multiple systems

Nice to have:

• Experience in pay-per-call, lead generation, performance or affiliate marketing, or insurance commission accounting
• Familiarity with Ringba or similar call-tracking platforms, Stripe, Zoho, and ad-platform billing
• ACCA, CPA, CMA, or equivalent certification (or in progress)
• Previous remote work for a US-based company
• Basic SQL or BI experience (BigQuery a plus)
• Experience with a company preparing for investment, a sale, an audit, or a QoE review

We offer:

• Competitive monthly pay of 3,000–5,000 USD, based on experience
• Fully remote, full-time position
• Direct access to the owners and real influence over how the company operates
• The chance to build a scalable, trusted accounting function in a data-rich, automated environment

How to apply:

Submit your resume and a brief summary of your experience with US GAAP, QuickBooks Online, month-end close, high-volume reconciliations, and internal controls. Please include your availability for overlap with US Eastern Time and your monthly compensation expectations

Job Type: Full-time

Pay: $3,000.00 – $5,000.00 per month

Application Question(s):

• How many years have you worked as a Controller, Assistant Controller, or AccountingManager?
• Do you have experience keeping books for US companies under US GAAP?

What You'll Actually Do:

· Make 100+ cold calls daily to dealership owners and managers

We build AI-heavy software for commercial real estate lenders, covering loan origination, servicing, document extraction, and financial analysis.

We’re looking for an AI Product Manager to own the path from requirements → development → QA → release.

This is not a traditional PM or project coordinator role. We use AI agents to do the mechanical work — drafting tickets, documentation, test cases, and other delivery tasks. Your job is to define the work precisely, build effective agent workflows, and apply judgment to what comes back.

Schedule — read before applying

This role connects a European development team with a US business team:

• 10:00–12:00 Kyiv time — development team, Mon–Fri
• 19:00–21:00 Kyiv time — US team, Mon–Fri

Both are fixed. The hours between are flexible. Apply only if this schedule works for you long term.

What you’ll own

• Product delivery: sprint planning, backlog, scope, priorities and capacity
• Requirements: feature specs, acceptance criteria, and keeping wiki/designs/tickets aligned
• AI workflows: build agents that generate tickets, documentation, test plans, etc.
• QA: test new features, run regression, validate AI document extraction, and file defects with evidence
• Design review: compare implementation against Figma and catch gaps before release
• Product: participate in scoping and design decisions and represent the user

What we’re looking for

• 3+ years in product management, delivery management, product operations, QA, or a combination
• AI is already part of your daily workflow
• Hands-on experience with AI agents / Claude Code / MCP / Claude Skills / Cowork or comparable tools
• You can write specifications precise enough for an agent to produce useful output
• Strong judgment about when AI output needs verification — and you actually verify it
• Comfortable with Jira, Confluence/wiki, Figma, PDFs, spreadsheets and structured data
• Strong spoken and written English and Russian
• Comfortable running calls with both technical and business teams

Not a fit if your background is primarily marketing, growth, sales, or content.

Nice to have

• Commercial real estate, lending, fintech or insurance
• QA experience
• SQL or basic Python
• Document-heavy B2B software

How we work

AI tools are paid for and expected to be used daily. Small teams, short release cycles, direct access to customers, and a lot of autonomy.

You’ll be the connection point between the European development team and the US business team.

Employment: [Contract / EOR / Full-time]
Benefits: [Benefits, equipment budget, learning budget]

Opportunity to grow into a Lead role and own the Growth Design direction as the team scales 

We're looking for a Senior Growth Designer to join our flagship B2C AI product and take ownership of one of the most business-critical parts of the user journey - the path from landing page through quiz to paywall, checkout and upsell.

‍You'll work hands-on with web funnels for paid traffic: landing pages, quizzes, paywalls, checkout, upsells and everything in between. The product operates at scale, so design here isn't just about making screens look better - it's about testing ideas, understanding user behavior and finding solutions that move conversion and revenue.

You'll partner closely with Growth, User Acquisition, Product, Analytics and Engineering.

Responsibilities:

• Design and iterate on web funnels - landing pages, quiz screens, and paywalls - built around specific hypotheses and A/B tests.
• Build reusable visual components for our internal funnel builder (quiz screens, paywall blocks, etc.) so the team can assemble new funnels quickly, consistently, and systematically.
• Contribute to product screens, user flows, and UX beyond pure growth work.
• Partner closely with Growth, Acquisition, and Product - pick up hypotheses, turn them around quickly and accurately, and keep status visible to the team.
• Own and maintain the design system and Figma hygiene - clean file structure, component consistency, and tracking of hypotheses and versions.
• Join syncs on key metrics, understand funnel performance, and let data - not just taste - drive design decisions.

What we look for:

• 4+ years of experience as a Growth Designer, Product Designer, or Web Designer, with a strong track record in web funnels and performance design.
• Strong understanding of web funnels and their business logic.
• Professional-level Figma - components, auto-layout, design systems, clean file organization.
• Hands-on experience with Claude Design.
• Solid analytical skills and comfort working with key metrics; understanding of conversion and funnel performance, with the ability to connect design decisions to results (deep analytics background not required - data-driven thinking is).
• Ability to quickly dive into complex problems and develop effective solutions.
• High level of autonomy and accountability.
• Creativity and ability to generate unconventional, bold hypotheses and fresh design directions, not just "safe" ones.
• Design expertise that goes beyond execution - developing alternative concepts and pushing back with arguments when a decision breaks the user flow.
• Strong results orientation and a focus on solutions rather than problems.
• English proficiency - B1 or higher.

Nice to have:

• motion/micro-animation skills, performance ad-creative experience, background in subscription or AI products.

What matters to this role:

• Proactivity and initiative - come with proposals rather than waiting for a spec; if you see a problem, bring a solution; follow through on what you commit to.
• Attention to detail - precision (text, elements, states) is part of what we mean by seniority.
• Communication and responsiveness - stay reachable, keep the team updated on status, and join urgent syncs when needed.
• Structured process - follow agreed workflows, track hypotheses and tasks, document decisions.
• Involvement in metrics and product - engage with growth and product numbers, participate in discussions on what worked, not just the visuals.

We offer:

• Real ownership and measurable impact - your work will directly influence funnel conversion, monetization, and the first-payment experience, with clear visibility into how design decisions perform.
• A strong voice in Growth decisions - you won't be treated as an execution-only designer. You'll have room to challenge ideas, propose alternatives, and shape how hypotheses turn into user experiences.
• A chance to build systems, not just individual screens - contribute to our internal funnel builder and create reusable design patterns that make experimentation faster and more scalable.
• A fast, data-driven environment - work closely with Growth, Acquisition, Product, Analytics, and Development, run frequent experiments, and see the impact of your work quickly.
• Competitive compensation based on your experience, expertise, and impact.
• Access to available AI tools.
• Reimbursement of professional courses and trainings.
• Flexible working hours.
• Professional equipment and access to the necessary programs.
• Paid vacations, sick days, and other benefits.
• Medical insurance.
• A variety of corporate events and team-building activities.

We are looking for a Senior System Analyst to participate in the preparation of a detailed Software Requirements Specification (SRS) for a complex enterprise platform.

The specialist will work closely with a Business Analyst and Solution Architect / Tech Lead. The BA is responsible for business and functional requirements, while the Solution Architect is responsible for the solution architecture. The System Analyst’s role is to detail system logic, data, and interactions to a level sufficient for architecture design, accurate development estimation, and subsequent implementation.

Key Responsibilities

- Analyze requirements, Features, Business Rules, and Use Cases prepared by the BA.
- Identify gaps, contradictions, ambiguities, and missing scenarios.
- Detail Use Cases: triggers, preconditions, main flows, alternative flows, exception flows, and postconditions.
- Describe system behavior and interactions between system components.
- Define object states and lifecycles: states, transitions, events, and constraints.
- Design and document APIs and integrations: endpoints, request/response structures, JSON/XML, authentication, error codes, callbacks/webhooks, retries, and timeouts.
- Prepare OpenAPI/Swagger specifications.
- Create Sequence, Activity, State Machine, Component, and other required UML diagrams.
- Work with BPMN 2.0 together with the BA.
- Develop data models: entities, attributes, relationships, identifiers, ERDs, and data mappings.
- Detail validation rules, error handling, edge cases, and system constraints.
- Describe synchronous and asynchronous interactions, events, queues, and integration flows.
- Define RBAC/permissions, audit requirements, and security-related system requirements together with the Solution Architect.

- Conduct technical requirements reviews together with the Solution Architect.
- Assess Features for Estimation Readiness and eliminate ambiguities that could affect development estimation.
 

Requirements

5+ years of experience as a System Analyst / Senior System Analyst.

Hands-on experience with:

Strong Advantage

Experience with Cybersecurity, telecom, security-sensitive enterprise systems, IAM, audit/logging, encryption, high-load, or distributed systems.

Cybersecurity domain experience is not mandatory if the candidate has strong system analysis and integration experience.

Еxpected Outcome

The SRS must be detailed enough that developers performing the estimation do not need to independently infer system logic, states, data structures, integrations, exception scenarios, or expected system behavior.

Important: We are looking for a hands-on System Analyst who independently creates specifications, models, and diagrams — not someone whose role is limited to team coordination or high-level requirements documentation.

I am Olena, I built Modaal.dev, an AI app builder that creates native Android apps in Kotlin and native iOS apps in Swift.  I’m looking for  brilliant people to help us get there by creating tons of cool TikToks, YouTube Shorts, and longer videos  

What you’ll do:

• Create and publish 2–3 videos a day, from short clips to 5–10 minute videos. These are examples of the style and quality you should be able to create: longer video · Short.
• When useful for your videos, build apps or prototypes with AI and show your journey—the wins, the failures, and the “wait, this actually works!” moments.
• Follow what people are building and saying about mobile vibe coding. Get inspired, learn from what works, and add your own twist.
• Write scripts and post copy, film yourself, edit, and publish on YouTube and TikTok.
• Experiment with different angles and re-record content with new hooks to see what works.
   

Who I’m looking for: You love creating videos and filming yourself. You know how to edit, what hooks and sub-hooks are, and how to keep people watching. You’re proactive and self-driven. I can share ideas and feedback, but I won’t manage your day-to-day work. You’ll take ownership and make things happen.

You use AI a lot in your everyday life. You’re technical enough to build apps with vibe coding tools and understand the differences between React Native, Swift, Kotlin, and Flutter.
