The client automates the daily operational workflows of hospital groups in Europe. The team is small — a tech lead and a CTO who write code themselves. We offer long-term, remote and full-time cooperation within usual CET working hours.

Location, in order of preference: Spain (a strong plus) · any EU country · Ukraine

What you will do:

— Own a set of automations end to end: build, deploy, monitor in production, fix.

— Automate hospital portals that have no API. These portals exist only in production — there is no test copy, and some actions cannot be easily undone.

— Verify your own output: there is no QA engineer and no QA team. You will not be left on your own — the tech lead and the CTO both write code daily and we share knowledge constantly — but checking your own area of work is your responsibility.

— Use AI coding agents daily; you review and stay responsible for everything they produce.

Stack

Python 3.11+ · Playwright (async Python) · Prefect 3 · PostgreSQL (SQLAlchemy 2, Alembic) · Pydantic v2 · FastAPI · uv (package manager) · AWS (ECS, S3, CloudWatch) · Textract and Bedrock (OCR and LLM in production) · Docker · GitHub Actions.

Must have:

— Python in production — automations or services you built and ran yourself, not only in test.

— Browser automation of a portal with no API — Playwright, Selenium or Puppeteer, on at least one real, live site you automated yourself.

— Actions that cannot be undone — a repeated or resumed run never performs a completed action twice: idempotency, checkpoints, dry runs, a check before the action.

— You verify your own output — against the real data: in logs, in the database, in the output itself.

— Systems thinking — you consider how a change affects the systems around it, and you direct AI agents while keeping control of the code.

• English B1+

Nice to have

Healthcare or another regulated domain · experience on teams with no staging environment and no QA team · building your own tooling around AI agents · Italian or Spanish.

We need a senior engineer who owns the question of whether our AI features actually work. About 70 percent of the job is quality and evaluation in agent-based development: harnesses, datasets, regression gates, and the standards around them. The other 30 percent is raising the quality of everyone else’s product work. You review code across the Node, React, and React Native apps, coach engineers on resilient design, and shape features before they are built. You write production code too, but to keep your judgment current, not as your primary output.

That stack is Node services, React and React Native front ends, PostgreSQL, and AWS. Playwright for web, Maestro for mobile, GitHub Actions for CI.

If you want a pure test automation role, this is not it. If you want to be the person who defines what good means on a team building with coding agents, and who has the credibility to hold that line in review, keep reading.

What you will own

Quality and evals, about 70 percent of the work

• Eval harnesses, golden datasets, and scoring for production agentic workflows.
• Regression gates in CI. Nothing merges without an eval verdict.
• The Playwright web and Maestro mobile end-to-end suites. Fast, and honest about failures.
• Engineering standards: code review practice, architectural patterns, targeted refactors.
• Production instrumentation for AI features, and the loop that turns real failures into new eval cases.

Product craft and resilience, about 30 percent of the work

• Code review across the Node, React, and React Native codebases. Not rubber stamps. Specific feedback that leaves the author better than you found them.
• Coaching on resilient design: error handling, retries and idempotency, failure isolation, and the tests that prove the behavior.
• Quality designed into features up front. You are in feature design early, not reviewing at the end.
• Light hands-on contribution to production code, enough to keep your review credibility and your context current.
• Game day. When something breaks on a Saturday, you are in the troubleshooting: reading traces, reproducing the failure, and driving it down.

Requirements

• 5+ years building and operating production web software.
• Strong JavaScript and TypeScript. You know the runtime, not just the framework.
• Node and React in production. React Native shipped to the app stores is a strong plus.
• PostgreSQL: schema design for read patterns, index design, query plans, migration under load.
• AWS in production: ECS or Lambda, Secrets Manager, CloudWatch, IAM. You can read the bill.
• Playwright or equivalent, used on a suite you personally had to keep green.
• CI/CD work in GitHub Actions, including making a slow pipeline fast.
• A track record of raising code quality: reviews, architectural patterns, refactors that landed.
• You have reviewed and mentored other engineers on production code. You can name specific practices that spread across a team because of you.
• Strong asynchronous written communication.

AI engineering and evaluation

A hard requirement, not a preference. Expect detailed questions.

• Daily work with frontier models and agentic coding tools such as Claude Code, Codex, or Cursor.
• Evaluations you built yourself for an LLM or agent system. What you scored, how you scored it, and what you did when the score moved.
• Dataset construction. You can explain how you sourced cases, handled labeling, and kept the set from going stale.
• Judgment about failure modes. You can name the ways an agentic workflow breaks that a unit test will never catch.
• A repeatable method for giving agents context: instruction files, tool definitions, MCP servers, subagent roles.
• Cost awareness. You track token spend and wall-clock time per unit of shipped work.

Nice to have: eval platforms such as LangSmith, Braintrust, or Langfuse; agent frameworks and SDKs; internal tooling and MCP servers; mobile end-to-end testing; multi-tenant SaaS; sports, scheduling, or field-services domains

Mission of the Role:

You are the first content hire and the first public face of the brand: you own the engine end-to-end, from strategy to the post itself, across Instagram, LinkedIn, and X, with an AI stack that lets one operator do the work of a small content team. Turn longevity science (dense, fragmented, intimidating) into content American consumers actually understand, save, and share.

Core Responsibilities:

• Own the content strategy from zero: positioning, tone of voice, content pillars, and a rolling monthly calendar for a US audience. There is no brand book and no brief waiting for you. You write both.
• Run the channels end-to-end: Instagram (Reels, carousels, Stories), LinkedIn (including posts under the founder's name), and X. Each channel gets native formats, not one post copy-pasted three ways.
• Produce the creative yourself: visuals in Canva/Figma, short-form video shot on a phone and cut in CapCut. There is no designer and no producer. Taste is part of the job spec.
• Build the community: comments, DMs, early-user relationships. The first cohort of people who care about Chia is yours to find and keep.
• Own social metrics end-to-end: reach, engagement, saves, follower growth by channel. Weekly hypothesis → test → learning loop, documented so it compounds.
• Run an AI-native content workflow: Claude/ChatGPT for research and drafts, Midjourney/Ideogram for visuals. Target: content throughput that would otherwise require three people.

Requirements:

Must have:

• 2–4 years in social media / content / community at a US-facing product company: in-house, not agency or outsourcing. You owned a brand, you didn't execute someone else's brief.
• Native or near-native English: you write for a US audience with cultural fluency and a real voice. This is a writing role in English; there is no localization step and no editor behind you.
• A portfolio of live accounts you personally ran, from strategy through publishing. With numbers, and with an honest account of what didn't work.
• Full-cycle execution: idea → copy → visual → publish → analyze, done by you, without handoffs.
• Instagram as your core surface: Reels, carousels, Stories, and the direct-message layer underneath them.
• Hands-on creative production: Canva (required), Figma (plus), phone-shot video and CapCut editing.
• Comfort with ambiguity: pre-seed means there's no playbook. You're inventing the process while running it.
• Strong AI workflow practice: daily Claude/ChatGPT use, hands-on with content automation.
• Personal interest in the topics: health, wellness, longevity.

Nice to have:

• Professional background in longevity, wellness, healthspan, or biohacking.
• Track record launching an account from zero to a meaningful US audience.
• Experience building a founder's personal brand.
• Familiarity with FDA-friendly marketing claims (or willingness to learn fast).
• Pre-seed/seed startup experience where you had to invent the playbook, not follow one.

Explicitly not a fit:

• Strategists who direct a team of designers and copywriters: there is no team.
• Performance/paid acquisition specialists: that is a different role at Chia.
• Portfolios of polished decks with no live accounts behind them.
• Anyone whose English works for messaging but not for writing brand voice.

Expected Results (Probation KPIs, 90 days):

Day 30: Content strategy and tone of voice documented and approved. All three channels live and posting on a consistent cadence (target: ≥X posts/week per channel, we'll align on numbers). Baseline metrics established.

Day 60: A repeatable weekly content engine running (concept → creative → publish → review) with the founder-voice LinkedIn track fully owned by the SMM. Measurable engagement and follower growth vs. the Day-30 baseline, with documented learnings.

Day 90: Content calendar owned independently one month ahead. At least one format proven to outperform baseline and scaled. Community layer active: DMs and comments handled within 24h, first cohort of ≥Y engaged US followers identifiable.

Qualitative: CEO trusts the SMM to publish under his name without line-editing. Content ideas originate with the SMM, not with the founder.

What to Expect in the Interview Process:

• Culture Fit / Soft Skills Interview (up to 60 min), with Recruiting Manager. Values alignment, communication style, and vibe check. We're listening for directness and clarity of thinking.
• Work Product Review / Portfolio Deep-Dive. Candidate walks through 2–3 live accounts they personally ran: what the strategy was, why those formats, what the numbers did, what they'd do differently. No prep needed: real accounts, not a polished version. We're looking for taste, systems thinking, and honesty about what flopped. We follow up within 3 business days.
• Technical Interview with CEO (60 min). Deep dive into hard skills: what you built, decisions made, what you'd do differently. We also cover Chia's mission and your motivation for working in longevity at pre-seed.
• Test Assignment (up to 1 hour, if needed). One short, realistic task (for example, a founder-voice LinkedIn post or a Reels script for Chia) if the portfolio left open questions. If it didn't, we skip this step.
• Reference Collection. 2–3 references from former managers or collaborators. We actively probe for challenges and failures, not just highlights.
• 2-week paid trial. Real tasks with the team, mutual evaluation: the first two-week content plan, live posts, and the AI workflow in action happen here, paid, not as an unpaid take-home.
• We send candidates a short prep doc with links to our product, market, and content references, so everyone walks into the process with the same baseline.
