Stealth LLC

We are a new-generation international product FinTech company with AI at the core of our technology. We use it to rethink how software is built, turning business ideas into production-ready solutions faster than ever.

Every engineer gets access to top-tier AI subscriptions with no usage caps, giving you the tools to solve problems, automate workflows, and ship from day one.
 

What you will do:

• Own features end to end, from understanding the business need to shipping to production, measuring results, and closing the loop with the requester.
• Turn business needs into detailed ClickUp tasks with AI, including context, acceptance criteria, and edge cases.
• Delegate implementation to AI coding agents, review their plans, and verify results using automated tests, review agents, and nightly red-team runs. Manually check anything involving money, security, or merchant data.
• Own the infrastructure behind your work, including servers, CI/CD, monitoring, and incident response.
• Build agents and automations for other teams. If something is done manually twice, automate it.

Requirements:

• Daily use of AI coding agents (ideally Claude Code), with real examples to show.
• Shipped production backends in PHP and/or Go. What you built matters, not years.
• Strong fundamentals (SQL, APIs, concurrency, security) to catch AI when it is confidently wrong.
• Hands-on DevOps: Linux, Docker, CI/CD, monitoring.
• Owner mindset: why before how, and you measure the result.
• Clear English (B2+) with the team, clients and vendors.
• Nice to have: payments or high-risk verticals, your own agents or MCP servers, a startup or side project with real users, security hardening.
   

Nice to have:

• Experience building custom agents, MCP servers, or AI workflows.
• Background in payments, acquiring, card schemes, or high-risk industries.
• A startup, freelance, or side project with real users or revenue.
• Experience with encryption, server hardening, or security audits.
   

Our tech stack:

PHP, Go, SQL databases, queues, caches, Linux servers, payment gateway APIs, and bank APIs - you don't need to know everything on day one.

What we offer:

• AI tools without the usual limits: Top-tier Claude Code subscriptions and internal AI tools.
• Real ownership and impact: Ship to production in days and work on systems processing significant payment volumes.
• A company built around AI: A shared company knowledge base and agents across teams.
• Future-ready experience: Work at the forefront of AI-driven software development.
• Paid vacation: 20 working days of paid annual leave each year to rest, recharge, and return with new energy.
• Paid sick days: 1 paid sick day per month, up to 10 days per year, with no medical certificate required. Certified medical leave is covered in accordance with UA law.
• Birthday day off: One additional paid day off to celebrate your birthday or simply take some time for yourself.
• Company equipment: Corporate equipment is provided after 6 months of full-time work.
   

Hiring process:

Three steps, usually about one week from the first call to an offer. AI tools are welcome throughout.

1. Intro call (40–60 min): Discuss your motivation, how you use AI, and a recent project you shipped with agents.
2. Practical case (about 1 hour): We provide a vague business request. You return a ClickUp-style task written with AI, the agent session log or a short screen recording, the working solution, and a note explaining what you verified with AI versus checked manually.
3. Live session with the CTO (15–30 min): Walk us through your solution, adapt to changing requirements, and drive the agents live. The founder may join at the end.
    

We make a decision within 48 hours of the final step.

About us

We are a new-generation international production company where talent, business, and technology come together to create what comes next. We believe the biggest breakthroughs happen when ambitious people embrace new ideas and use new technology and AI without limits.
 

We are currently looking for a Finance & Payment Lead who will own the accuracy of every figure in our books. With AI covering most of the routine work, we need someone who digs into the data, directs the tools, reviews every output, and personally fixes whatever doesn’t add up.
 

This role is for you if you have:

• A doer approach with a strong ownership: you treat an unexplained $1 as a personal problem until you find the answer.
• Rigour and fast learning: you’re obsessed with where every number comes from, and you keep learning on your own.
• AI fluency: you use AI tools daily to analyse data, reconcile files, write scripts and automate routine work.
• Hands-on team player: you work side by side with a small team, sharing knowledge and setting the pace by example.
• Flexibility beyond a classic 9-to-6: payments run 24/7, so you’re fine with occasional weekend work and being reachable for urgent issues.
• Advanced English; Ukrainian is a plus. 

What you will do:

• Daily reconciliation: match PSP settlements, bank and internal ledger across all processors, tracking every fee, reserve, chargeback, refund and FX spread.
• Recovering funds: find missing or withheld money and follow up with processors personally until everything is settled.
• Audit and close: review flows, controls and AI-produced reports line by line, and prepare external audits and the month-end and year-end close.
• Payments and treasury: make and approve outgoing payments, and manage the cash position across accounts and currencies.
• Smart monitoring: build your own dashboards and alerts with Claude so anomalies surface within hours.
• Working side by side: work hands-on with a small team.

What we offer:

• Meaningful work: Own a critical function with a visible impact on the business and its financial health.
• Freedom to lead: Take ownership of your area, make decisions independently, and shape how finance control works at the company.
• AI-first environment: Work in a company where AI is part of everyday processes, and build the tools that make them better.
• Paid vacation: 20 working days of paid annual leave each year to rest, recharge, and return with new energy.
• Paid sick days: 1 paid sick day per month, up to 10 days per year, with no medical certificate required. Certified medical leave is covered in accordance with UA law.
• Birthday day off: One additional paid day off to celebrate your birthday or simply take some time for yourself.
• Company equipment: Corporate equipment is provided after 6 months of full-time work.
