Location: Remote (US/EU time-zone overlap required) 

Type: Full-time 

Reports to: Board of Directors

The role: 

UEX.US is a cryptocurrency exchange shipping Trading Pro, a savings/rewards product, and a payments stack. We move fast, and we ship. What we don't yet have is one person who owns the answer to: Is this product actually good, is it actually competitive, and does it actually do what we told users it does?

That's this job. You are the user's advocate inside the building and the quality gate for the devs.

This is an AI-first role: We are not hiring a product manager who occasionally uses ChatGPT. We are hiring someone who has rebuilt their entire working method around AI and produces the output of a four-person product team. If that isn't already how you work, this role will be uncomfortable, and you should not apply.

What you'll own:

- User feedback as a system. Discord, support tickets, app-store reviews, churn conversations — pulled in continuously, tagged, quantified by AI pipelines you build and maintain, turned into a ranked list nobody has to argue about. Anecdote becomes evidence, weekly, without a research team.

- Competitive intelligence, continuously. Binance, Kraken, Bybit, Coinbase, MEXC, Gate. Fees, spreads, listings, UX flows, onboarding friction, what they ship weekly. Automated monitoring and AI-generated teardowns — you should know what our competitors changed this week before they announce it.

- Test everything we already have. Every existing feature, hands-on, repeatedly — deposits, withdrawals, order types, KYC, rewards accrual, mobile. AI-assisted test scripts and regression checks where they help; your own hands where they don't. You find the breakage before users do.

- Promise integrity. Every claim on the site, in the app, in the ToS and in support macros must match what the product actually does. Where it doesn't, you flag it and drive it to zero. This is a regulated money services business — a UI label that overstates what a feature does is not a copy problem; it's an exposure.

- Priority discipline. You set the roadmap with the board, then you make it real: specs the devs can build from, acceptance criteria, sprint follow-through, and honest weekly status. Shipped-and-verified, not shipped.

- Metrics. Define them, instrument them, report them. Activation, retention, volume per active trader, support-ticket rate per feature.

## AI requirements — the hard bar

This section carries the most weight in our evaluation. You must be able to demonstrate, live, in the interview:

- Daily production use of frontier models (Claude, GPT, Gemini) as your primary working environment — not as a novelty, as the place your work happens.

- Prompt engineering at a professional level: structured prompts, XML/JSON output contracts, few-shot examples, chain-of-thought, evaluating and iterating on prompt quality rather than accepting first output.

- Building repeatable AI workflows, not one-off chats. Projects, custom instructions, saved prompt libraries, reusable analysis templates that a teammate could run.

- AI over large unstructured datasets: feeding thousands of support tickets, Discord messages and reviews into a pipeline that returns a defensible, quantified priority list — and knowing how to check that it didn't hallucinate the numbers.

- Agentic and tool-using AI: Claude Code, Cowork, MCP connectors, browser agents, or equivalent. Comfortable letting an agent run a multi-step task and reviewing its work.

- API-level literacy. You can call a model API directly, batch a job, chain calls, and estimate what a workflow costs before you run it. Light scripting (Python or JS) to glue things together.

- AI-assisted data work: natural-language querying over product data, generating SQL and validating it, building dashboards without waiting on an engineer.

- AI for spec and QA production: drafting PRDs, acceptance criteria, edge-case enumeration, test matrices, and user-facing copy — then editing hard, because the first draft is never the shipped one.

- Judgment about where AI fails. Hallucination, false confidence, stale knowledge, silent arithmetic errors. You verify anything that touches money, compliance language, or a user-facing promise. AI output that reaches a customer is your responsibility, not the model's.

- Discretion. You understand what customer data, KYC material, and internal financials may and may not be pasted into a third-party tool.

In the interview, you will screen-share your actual setup and run a real task in front of us: take a raw dump of feedback and produce a ranked, evidence-backed priority list, live. We are evaluating your workflow, not your vocabulary.

Who you are:

- 3+ years in product, ideally consumer fintech, trading, or crypto. Exchange experience is a strong plus.

- You've traded. You understand orderbooks, spreads, slippage, fee tiers, custody, and on-chain settlement well enough to argue with a trader and be right.

- SQL or equivalent; comfortable in analytics tools without waiting on an engineer.

- Obsessive about detail and unbothered about saying "this isn't ready."

- Written English strong enough to write specs and user-facing copy.

Nice to have: experience with a licensed/regulated platform, market-maker or API-trader relationships, design sense, Russian/Ukrainian or Spanish.

How we work:

Small team, no bureaucracy, decisions in hours, not weeks. You report directly to the board and work day-to-day alongside the engineers. AI tooling and API budget are provided — we expect them to be used.

Compensation is $2,500–$4,500/month during the 3-month remote test period, increasing to $6,000/month after relocating to Madrid.

Who we are

We build APIs and tools for businesses working with creators. We're profitable, growing 30% month over month, and our founders have sold three businesses for seven figures or more.

We're expanding into a single API for multiple creator and social platforms. Customers should be able to integrate once and get consistent responses, webhooks and SDKs.

The work

Some platforms have undocumented APIs, bot detection and changes that arrive without notice. We need someone who can understand how those integrations work and keep them reliable when the platform, traffic or data changes.

We're hiring a senior full-stack engineer to keep production reliable and customer data correct. You'll plan for a workload of 50 million jobs a day, including bursts, slow upstream services and retries. You'll also build integrations and customer-facing features in Laravel 13, Inertia and React.

What you'll do

• Investigate production problems using logs, metrics and the actual request and job flow. Identify who is affected, contain the problem and verify the fix.
• Keep queues and webhook delivery reliable. Handle retries, duplicate events, rate limits and worker failures without losing data or letting one account hold up everyone else.
• Reverse engineer undocumented APIs and maintain integrations for authentication, posting, messaging, media and analytics.
• Make different platforms work through a consistent API. Keep documentation, SDKs and MCP tools aligned with the behaviour customers receive.
• Build useful dashboards and internal tools in Laravel 13, Inertia and React. Make the data accurate and the interface clear.
• Improve database queries, worker capacity and scheduling based on measurements. Add tests for the failures we cannot afford to repeat.
• Protect our APIs against abuse and check integrations when upstream behaviour changes.
• Challenge a decision when you think we're solving the wrong problem. Explain the alternative and its tradeoffs.
• Production incidents and incorrect customer data take priority. We agree with the team which integration and product work comes next.

What we need from you

• You've shipped and maintained Laravel applications with real users, and you're comfortable building in React. Inertia experience helps, but is not required.
• You have operated queue or worker systems in production at substantial volume. You understand concurrency, retries, duplicate execution, backpressure and how databases and external services limit throughput.
• You can describe a production incident you personally investigated, the evidence that led to the cause and how you proved the fix worked. Explain the workload you owned in concrete numbers.
• You have reverse engineered an API, web client or similar integration. You can reason about HTTP headers, cookies, request signing, TLS fingerprints and rate limits.
• You check that data means what the product says it means. Missing information, failed requests and legitimate zero values need different handling.
• You use AI regularly and can show how it improves your work. You verify its output and understand the code you ship.
• You investigate problems independently, keep the team informed and raise blockers early. You know when to involve someone else in a decision.
• You don't need to have handled exactly 50 million jobs a day. Tell us what you have operated, how it failed and how you measured its limits.

Nice to have

Proxy infrastructure, published SDKs, OpenAPI, MCP tools, security testing, PostHog or experience with creator platforms. Public code is welcome; confidential commercial work also counts if you can explain your contribution.

How we work

We're a small team. We work asynchronously and review progress weekly. Keep the team informed about decisions, blockers and incidents. We care about work reaching customers and continuing to work after release.

We will discuss working-hour overlap, incident coverage, response expectations and any on-call arrangement before an offer.

Remote, with a Prague office available. Czech Republic, Ukraine, Poland or UK preferred.

How we hire

A paid debugging exercise, a 30-minute technical walkthrough, then a decision. We agree a fixed fee before you start, and payment does not depend on the hiring decision. You have six-seven 🤷‍♂️ hours, including setup. The process usually takes under two weeks. You can use AI throughout; we'll ask you to explain your code and decisions.

Apply

Briefly describe a production problem you investigated, how you found and verified the fix, and the traffic or job volume involved. Tell us how you use AI and give an example of something you caught it getting wrong. A concrete example gives us more to talk about than a cover letter.
