About QOVES
QOVES is a technology company pioneering facial aesthetics, helping consumers make smarter beauty decisions. Every day, people make important decisions about their appearance based on guesswork or generic advice. We help them decide with clarity instead. Our platform gives customers a clear, science-backed understanding of their face, paired with bespoke advice on how they can look better. Our work reaches millions: more than 2.5 million people follow QOVES across platforms and most importantly, our customers are delighted, with 4.8 stars across 600+ reviews; we believe this reflects the care and sensitivity with which we approach everyone who comes to us for guidance. We're a profitable, growing company headquartered in London, with a team across the globe. What guides us is simple: people deserve more than one-size-fits-all advice when it comes to their appearance. Every decision we make (from the science behind our models to the way we communicate results) is grounded in evidence, responsibility, and a broad, inclusive understanding of beauty.

About the Role
You will join the backend team building the computer vision and machine learning systems that power QOVES's facial analysis platform. The non-negotiable is proven production experience: at least 3 years building scalable software in Python, with hands-on work shipping AI or ML features, including computer vision or LLM-based systems, into a live codebase. You will work closely with the AI Research team to translate research prototypes into production-ready code, own delivery end to end across analysis, design, coding, testing, deployment, and support, and optimise applications for performance and scalability as usage grows. You will also work with the wider team to spot problems early and resolve them before they become blockers.

What We're Looking For
• 3+ years of professional experience in production-level scalable software development with Python
• Strong proficiency with Python for building production-grade APIs
• Hands-on experience integrating AI or ML features, including computer vision or LLM-based systems
• Solid grasp of software architecture principles and API design, with the ability to contribute meaningfully to architectural decisions
• Experience owning work across the full software development lifecycle
• Strong sense of code quality, testing discipline, and engineering best practices
• Excellent communication skills, with the ability to articulate trade-offs and design decisions clearly
• A collaborative, proactive mindset with strong problem-solving skills

Nice to Have
• Knowledge of MLOps practices and experience with Data Version Control (DVC) or similar tools
• Knowledge of data pipelines, including designing production-grade GPU inference pipelines for high-throughput workloads
• Exposure to frontend or full-stack development
• Experience working in a startup or fast-paced product environment
• Experience building data pipelines or working with large-scale data processing

Why Join
• Build the computer vision and machine learning systems behind a product used by millions
• Fully remote with real autonomy and direct collaboration with the AI Research team
• A profitable, growing company with a global team

Compensation and Logistics
• Remote, full-time, open to applicants worldwide
• Compensation competitive, based on experience

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.
