About the Role

• Reproduce issues and identify potential root causes.
• Develop and maintain automated tests and scripts using Java or Python.
• Create scripts to automate repetitive troubleshooting and support tasks.
• Improve existing automation and scripting solutions.
• Collaborate with developers and other engineers on investigation and resolution of complex issues.
• Document findings, solutions, and troubleshooting steps.
• Identify recurring issues and suggest ways to prevent or automate their investigation.
• Take ownership of assigned tickets and technical problems from investigation to resolution.

What We’re Looking For

• 2–3+ years of commercial experience in Automation QA.
• Strong knowledge of Java or Python.
• Hands-on experience with test automation and scripting.
• Experience troubleshooting technical issues and working with logs.
• Good understanding of APIs and HTTP.

• Ability to communicate technical findings clearly to developers and other stakeholders.

Nice to Have

• Experience with L2/L3 technical support.
• Experience with microservices.
• Experience with Kafka.
• FinTech or Payments domain experience.

Why Join FreySoft?

🌍 Work with international clients across different domains and modern technology stacks.

🚀 Work on real production issues and solve challenging technical problems.

🎯 Develop your expertise across automation, troubleshooting, and scripting.

🤝 High level of ownership and trust—you’ll have the freedom to investigate issues and improve processes independently.

💡 AI-first engineering culture that values responsible use of modern development tools.

💰 Competitive compensation based on experience and impact.

You'll own design end-to-end — from problem to shipped UI. The role leans UI: visual craft is what sets the bar here. You'll work shoulder-to-shoulder with Head of Product and CTO on what to build and why.
And you'll do all of it with AI deeply embedded in your workflow — for content generation, prototyping, exploration, and production.

What you'll do

• Design end-to-end flows for the SkinnyRx app and web — onboarding, patient dashboards, intake, billing, content surfaces
• Generate and direct AI-produced content — product imagery, illustration, lifestyle photography, micro-animations, video — at a quality that feels intentional, not stock
• Prototype interactively — in Figma when you need precision, in code (via AI tools) when you need realism
• Partner with product, engineering, copy, and marketing on tight shipping cycles
  
  What we're looking for
• 5+ years in product design with a strong UI portfolio of shipped consumer work
• Deep, daily AI tooling across the workflow:
  • Imagery and video: Midjourney, Sora, Runway, Kling, Nano Banana
  • Code prototyping: Cursor, Claude Code, Codex
  • Production: Figma AI, MCP-based workflows
• Self-direction. You come back with options, not blockers
  
  Why join
• Fully remote, async-friendly, any timezone
• High ownership, weekly shipping
• Generous tooling budget — every AI subscription you need
• Comp scaled to your level

Remote | Spanish C1+ | Product IT Company
 

We are helping our partner, a growing product-focused IT company, find a Sales Manager to support and expand their presence in the Spanish market.

This is not a role focused on aggressive sales tactics, rigid scripts, or endless cold prospecting from scratch.

We’re looking for someone who genuinely enjoys working with people, thrives in conversations, and wants to grow within an international business environment while becoming an expert in a valuable product.

About the Role

This position sits somewhere between Sales, Account Management, and Customer Success.

We’re not simply looking for someone who can sell.

We’re looking for someone who wants to understand customers, identify their needs, help them find the right solutions, and build long-term relationships based on trust.

What You’ll Do

• Communicate with customers across the Spanish market.
• Introduce and explain the product’s features and capabilities.
• Work with existing customers to maximize product value.
• Re-engage customers who have stopped using the platform.
• Reach out to potential customers using prepared contact databases.
• Conduct phone calls, online meetings, and day-to-day customer communication.
• Maintain accurate records in the CRM system.
• Identify customer needs and recommend appropriate solutions.
• Collect and share customer feedback with the Product Team.
• Contribute to the growth and development of the company’s Spanish market operations.

Who We’re Looking For

We would love to hear from you if you:

• Have Spanish language proficiency at C1 level or higher.
• Communicate confidently and naturally with different types of people.
• Enjoy building relationships and earning customer trust.
• Have experience in Sales, Account Management, Customer Success, Customer Support, Client Relations, or Call Center environments.
• Are comfortable working with both existing and potential customers.
• Enjoy learning new products and understanding customer businesses.
• Are motivated by personal and professional growth.

Nice to Have

• Living in Spain or previous experience living in Spain.
• Experience working with B2B customers.
• Experience selling to or supporting Spanish-speaking markets.

• Familiarity with the Spanish business culture and communication style.

   

What Matters Most

More than previous experience, we value people who:

• Take ownership and responsibility for their work.
• Are proactive and solution-oriented.
• Enjoy learning and continuous development.
• Are curious and ask thoughtful questions.
• Work collaboratively and support their teammates.
• Respect customers and colleagues.

• Are interested in building long-term relationships rather than chasing short-term wins.

   

What the Company Offers

• A role within a product-focused IT company.
• The opportunity to contribute to the growth of an international market.
• Full product training and ongoing support from the team.
• Real opportunities for career development and internal growth.
• A culture built on trust, ownership, learning, and initiative.
• Fully remote work format.

• Competitive fixed salary plus performance-based bonuses.

   

Why This Opportunity?

This role is ideal for someone who wants more than a traditional sales position.

You’ll have the opportunity to become a trusted advisor for customers, help shape the company’s growth in Spain, and develop your career within a supportive and ambitious team.

If you’re excited about working with the Spanish market, building meaningful customer relationships, and growing alongside a strong product business, we’d love to meet you.

We build and run AI agent systems for founders. Four are in production — German real estate, US legal tech, executive assistance, enterprise HR analytics — with paying clients since 2023 and revenue that renews monthly.

Every one of those clients arrived by referral. Nobody here has ever gone out and found one.

That's the seat. You'd be the first person to do outbound at this company.

What we sell

Technical ownership of a founder's roadmap and its execution, from one person. One weekly call, cancellable at the end of any month. The price is published, not quoted.

Who buys it

Two shapes, and they buy for different reasons:

• A founder with no technical half. Non-technical, or technical enough to judge the work but not to own it. Has money and a specific thing they want to exist, and nobody who can build it. This is often one person — headcount doesn't bound it
• A 3–20 person company with deep domain expertise, owner-operated, doing something valuable by hand. They know their domain better than we ever will and have nobody who can turn it into a system

What they share is that the person on the call is the one whose money it is, and that nobody inside can build the thing.

What you'd do

• Find both shapes — the second one is the half most people forget, and it's the one that's already profitable
• Verify each one against four checkable facts, before any meeting is booked
• Get them onto our founder's calendar
• Sit on the scoping call — you're on every one of them
• Target: four qualified founders a month. That's the entire KPI

What we're looking for

• 2+ years selling custom software development or dev services. Not SaaS seats, not staff augmentation
• At least one deal you closed where the signer was the founder
• You can see when a founder is about to buy, from public signals. Ours have been: money already spent on a prototype with nothing running; an engineering role open for months at a company too small to assess the candidates; the one technical person just left and the roadmap went with them. And on the domain-expertise side: a third hire into the same manual role, or an ops ad whose responsibilities read as a list of steps
• You can tell a real buyer from a curious one before we spend an hour on them
• You work without being managed. There is nobody here to check in on you, set your week, or notice you've stalled. The target is the only instruction you get
• English B2 or better

Format

• Fully flexible, your own hours, we are okay with you being employed somewhere else at the same time or running your own business
• Independent contractor, commission-based — paid per qualified meeting and per closed deal. No base. Figures and full terms come in a two-page sheet after we've talked

Aero is an international team of engineers based in Ukraine. The company was founded in August 2026 and raised its first round of capital.

We're looking for an Aircraft Designer / Aerodynamics Engineer to join the core build team and own the aerodynamic and aero-structural design of an airframe — from CFD and stability analysis through to a flying prototype and first deployments.

What you'll do

• Design and iterate the BWB airframe geometry, balancing aerodynamic efficiency, stability/control, and shaping constraints.
• Run aerodynamic modeling and simulation (CFD, stability & control, performance envelope) to support design decisions.
• Work closely with the Head of Design on composite structure, control-surface actuation, and integration with propulsion and avionics.
• Iterate quickly across a batch-build, test-and-fly development cycle rather than a single "golden" prototype.

What we offer

• A decent stock option plan, but a modest salary for the first 6-9 months (the salary will be increased as soon as we accomplish the plan);
• Opportunity to create an aircraft with unique properties, drive the product development, and grow with us;
• Work in an international team that worked on world-famous products;
• Commitment to global security;
• A lot of work and fun in your new journey with us;
• Reservation from mobilization.

What we expect

• Proven experience and excellent knowledge of the domain;
• Team members learn Ukrainian, but English is still the main team language;
• A great and open-minded human being.
