AI-First Developer — Psychable

Location: Remote (US, Eastern Europe, China/Taiwan, or Latin America preferred; Miami is a plus) 

Reports to: Founder & CEO 

Type: Contract-to-hire / Fractional (Full-time path available) 

About Psychable

Psychable is the leading online community connecting individuals with professional, trusted psychedelic therapists, clinics, and wellness practitioners. We operate a content-rich WordPress platform with a practitioner directory, tiered membership program, integration courses, and a growing ecosystem of healing professionals, serving hundreds of thousands of monthly visitors in one of the fastest-evolving sectors in health and wellness.

We are founder-led, mission-driven, and independent. We are at a critical inflection point: the vision is clear, the audience is growing, and the infrastructure needs to match the ambition.
 

Why This Role Exists

Psychable has built meaningful traction on a WordPress foundation with a small, scrappy team. But we've reached the ceiling of what manual processes and off-the-shelf plugins can support. We need someone who can look at what we've built: the directory, the membership tiers, the content engine, the data we're sitting on, the practitioner relationships, and architect the systems that turn all of it into a scalable, revenue-generating machine.

This is not a "maintain the website" role. This is a build-the-engine role.

We need someone who thinks AI-first, not as a buzzword, but as an operational philosophy. Someone who reaches for automation before manual process, who sees a spreadsheet of thousands retreat centers and immediately thinks about enrichment pipelines, who looks at our practitioner onboarding flow and sees where an AI agent could reduce it from 12 steps to 3.

What You'll Build & Own

Platform & Infrastructure

• Evolve our WordPress ecosystem, optimize, extend, or architect the path beyond it as needed
• Build and maintain the practitioner directory with intelligent match/search, filtering, booking integrations, and lead routing that actually works at the membership tier level 
• Implement payment systems, subscription management, and membership automation that reduce manual intervention to near-zero
• Ensure site performance, security, uptime, and SEO technical health across the platform

AI-Powered Automation

• Design and deploy AI agents and workflows that automate practitioner onboarding, lead distribution, content publishing, email/SMS campaign triggers, and data enrichment
• Build internal tools powered by LLMs (Claude, GPT, or equivalent) for content generation, data processing, and operational support
• Create automated pipelines for scraping, enriching, and activating practitioner and retreat center databases from public directories
• Implement AI-driven personalization, matching individuals with the right practitioners based on modality, location, availability, and fit

Data & Growth Systems

• Build the data layer we're missing: CRM integrations, analytics dashboards, membership metrics, practitioner engagement tracking, and revenue attribution
• Design outreach and enrichment systems that turn raw directory data into actionable sales and partnership pipelines
• Connect the dots between our content (SEO), our directory (discovery), our memberships (revenue), and our community (retention) with measurable, instrumented flows

Compliance & Trust

• All messaging systems (email, SMS) must be TCPA/10DLC compliant  
• Health content touches YMYL territory; any AI-generated or AI-assisted content pipelines must respect these standards
• Data privacy, practitioner confidentiality, and platform security are table stakes

Who You Are

You build with AI as a first principle, not an afterthought. You use Claude Code, Cursor, Copilot, or similar tools daily, not because someone told you to, but because you can't imagine working without them. You've shipped real things with AI agents, not just experimented.

You're a full-stack generalist who leans toward backend and systems. You can wire up a WordPress site, build an API, write a Python script to enrich thousands of records, deploy a Next.js frontend, and configure a CI/CD pipeline, all in the same week. You don't need a team of five to get something live. You lean it, do it yourself and get it done, even with AI agents.

You think in revenue, not just in code. When you look at a practitioner directory with tiered memberships, you see the funnel. You understand that the booking integration isn't a feature request, it's how members justify their $600/year. You ask "what does this unlock for the business?" before "what framework should I use?"

You're comfortable in ambiguity. We're a very resourceful team. Requirements won't always be spec'd out. You'll sometimes get a voice note and a Notion page and need to turn it into a working system. That excites you, not frustrates you.

You care about the mission. You don't need to be a psychedelic practitioner, but you understand that this work matters, that connecting people with the right healer at the right time can change a life. You approach the platform with that gravity.

Technical Environment

Current stack:

• WordPress  
• PHP / MySQL 
• Google Sheets / Notion  
• GHL or similar  
• Slack 
• Various WordPress plugins for directory, membership, and payments

What we expect you to bring or introduce:

• Python for automation, scraping, data enrichment, and AI agent workflows
• Experience with LLM APIs (Anthropic Claude, OpenAI) and building production AI workflows, not just prompting, but chaining, function calling, RAG, and agent architectures
• Modern frontend (React/Next.js) if and when we evolve beyond WordPress for specific surfaces
• API design and integration (payment processors, booking systems, CRMs, third-party directories)
• CI/CD, version control, and deployment best practices
• Familiarity with SEO technical requirements (site speed, structured data, crawlability, Core Web Vitals)

Nice to Have

• Experience building or scaling a marketplace or directory platform
• Background in health, wellness, or regulated industries
• Familiarity with Clay, Apollo, or similar data enrichment tools
• WordPress plugin development or WP REST API experience
• Experience with HIPAA-adjacent data handling

How to Apply

Send us:

1. A brief video on why this role calls to you, we want to hear your voice, not a cover letter template
2. One or two examples of something you've built where AI was core to the solution (links, repos, or a short writeup)
3. Your rate or salary expectations and preferred engagement structure (fractional, contract-to-hire, full-time)

We are very intentional. If the fit is right, you'll know within a week.

We welcome applicants of all backgrounds and believe that diverse perspectives strengthen our community and our platform.

About Amplifier AI

We’re building the next generation of surgical planning software for interventional radiology and cardiothoracic surgery. Our platform turns CT scans into interactive 3D models that help surgeons plan complex procedures—from endovascular aortic repair (EVAR) to transcatheter aortic valve implantation (TAVI) and beyond.

Our core library powers 17+ clinical analysis pipelines that perform automated anatomical segmentation, vessel centerline extraction, hemodynamic measurements, and risk stratification. Every algorithm we ship has a direct impact on patient outcomes.

We’re a small, focused team where your code goes from PR to operating-room screen in weeks, not quarters. If you want to work on technically challenging problems that genuinely matter, keep reading.

What You’ll Work On

This isn’t a generic backend role. Here’s what a typical month might look like:

• Extending our NNUnet-based segmentation pipelines (we run 15+ trained models across organs, vessels, bones, and tumors) and validating results against clinical ground truth

• Building automated measurement workflows—think aortic neck angulation, iliac tortuosity indices, or landing-zone diameter calculations that feed directly into surgical reports

• Developing new workspace modules: designing the data flow from raw DICOM volumes through preprocessing, AI inference, post-processing, and 3D scene generation

• Optimizing inference performance for GPU and CPU execution, including memory-aware scheduling and adaptive resolution strategies

• Working with SimpleITK, NumPy, and our in-house volume processing library to manipulate medical images at the voxel level—resampling, label morphology, island filtering, ROI extraction

• Collaborating directly with radiologists and surgeons to translate clinical requirements into algorithmic specifications

Our Tech Stack

• Language: Python 3.12+ (modern typing, dataclasses, async patterns)

• Medical Imaging: SimpleITK, NIfTI volumes, DICOM processing

• AI/ML: NNUnet framework, PyTorch, custom inference pipelines

• Infrastructure: Docker, NVIDIA GPU compute, CI/CD with automated testing

• 3D Visualization: Unity integration (you won’t write C#, but your Python outputs drive the 3D viewer)

• Tools: Git, Jira, Confluence, VS Code / PyCharm

What We’re Looking For

Must-haves:

• Strong Python fundamentals: you write clean, typed, well-structured code and understand performance trade-offs

• Experience with NumPy/SciPy for numerical computing—you’re comfortable thinking in arrays and transforms

• Familiarity with medical imaging concepts (DICOM, NIfTI, voxel spaces, coordinate systems) or strong willingness to learn quickly

• Understanding of machine learning inference pipelines, even if you’re not training models from scratch

• Ability to work independently in a remote-first environment with 4+ hours of overlap with CET business hours

Nice-to-haves:

• Experience with SimpleITK or ITK for image registration, segmentation, or morphological operations

• Background in NNUnet or similar medical segmentation frameworks

• Knowledge of 3D geometry: meshes, centerline extraction, spatial transforms

• Contributions to open-source scientific Python projects

• Domain experience in radiology, surgical planning, or health-tech

A Few Things to Know

To set expectations clearly, here’s what this role involves:

• The codebase is scientifically dense—you’ll work with Hounsfield units, anatomical coordinate systems, and clinical measurement standards. Curiosity about the domain is essential.

• We’re a startup. Processes are evolving, requirements shift, and you’ll sometimes need to figure things out from first principles rather than following established playbooks.

• This is primarily a backend/algorithmic role. If you’re looking for frontend or web development work, this isn’t the right fit.

• We care deeply about code quality—type hints, meaningful tests, clear documentation. We review each other’s work carefully.

Why Join Us

• Direct clinical impact: your code helps surgeons plan life-saving procedures more accurately

• Technically deep work at the intersection of AI, medical imaging, and 3D visualization

• Small team, big ownership: you’ll shape architecture decisions and see your ideas go to production

• Flexible remote setup with asynchronous communication and minimal meetings

• Competitive compensation with equity participation

How to Apply

About the Company

We're a European product company building automation for enterprise clients in regulated industries. Our systems process thousands of business transactions daily through web portals — correctness and reliability aren't aspirational, they're the product. A single wrong number in production isn't a failed test, it's a real-world operational impact on our clients.

The company is established and intentionally lean — experienced engineers, tight processes, zero bureaucracy. Leadership is hands-on — people who write code, debug production, and review PRs alongside the team, not just write requirements. Decisions happen in hours, ownership is real, and AI tools are part of our daily workflow — not an experiment. Our clients are in Italy, Germany, and the UK. You'll join an experienced team, remote-first.

Your Mission

Build the Python platform that drives enterprise web portals for our clients. You write services that process thousands of transactions daily — reliable, monitored, verified. You code, you debug in production, you own the outcome end-to-end. This isn't ticket-and-commit dev work — it's platform ownership.

What You'll Do

Core development

• Write Python services that orchestrate browser automation (Playwright), data flows, and API integrations
• Design retry logic, exception handling, and stateful workflows — real-world portals fail, your code handles it
• Build the backend that processes transactions end-to-end through forms, validations, and confirmations

Production ownership

• Debug overnight failures, investigate data anomalies, find root causes (not symptoms)
• Instrument services with logging, dashboards, and success-rate alerting
• Verify outputs and cross-check against source data — shipping is half the job, operating is the other half

Collaboration

• Active participation in team ceremonies — daily and weekly syncs, planning, retros. Video on, present, engaged.
• Real-time communication on Slack during working hours — fast responses, not "I'll reply tomorrow"
• Proactive status updates — flag risks and delays within hours, not days
• Clear written English for PRs, issue descriptions, and documentation

What We're Looking For

Must-have

• Python, 2+ years of production experience with code at meaningful scale
• Browser automation or stateful web interactions — Playwright, Selenium, or equivalent used in real projects
• Production ownership mindset — you check whether your code works in prod, not just on your machine
• Active AI coding tool usage with the habit of verifying AI output, not rubber-stamping it
• High-quality communication — you stay online, responsive, and engaged during working hours. If you prefer a low-communication, head-down-for-days style, this team won't feel right.
• Written English (B1+) — PRs, issues, docs
• Ukrainian FOP contractor — or able to register before start; we hire directly, not via EOR or staffing
• Overlapping CET business hours — active participation in team ceremonies with video on

Strong plus

• Workflow orchestration (Prefect, Airflow, Celery, or similar)
• REST API design and implementation (FastAPI, Flask, or similar)
• Data pipelines, ETL, and data validation
• AWS basics (ECS, S3, Lambda, CloudWatch)
• SQL (PostgreSQL) for data verification and analytics
• Docker

What We Offer

• Remote-first — work from anywhere in Ukraine or EU
• AI-native environment — we provide licenses for Claude Code, Cursor, or equivalent
• Level-based compensation — $2,200-4,500 net/mo, positioned at Middle, Senior, or Lead based on demonstrated depth. Structured review after probation.
• Direct impact — your work protects real client operations in production
• Lean team — no bureaucracy, decisions happen in hours, your contribution is visible
• Stack: Python, Playwright, AWS, PostgreSQL, Docker, CI/CD

Why This Role

You'll work directly with engineering leadership that stays in the code — writing automation, debugging production, and reviewing PRs with you. No layer between who decides and who builds, no HR filter between you and product decisions. The role has ~60% production maintenance (debugging failed runs, fixing overnight issues, investigating data anomalies) and ~40% building new automation workflows. If you want pure greenfield coding all day, this isn't it. If you want ownership of something real in production, it is.

We hire at Middle, Senior, or Lead — we don't pre-define your level. The interview decides based on demonstrated technical depth and ownership. Compensation scales accordingly within the $2,200-4,500 net band. A structured review after probation adjusts level and pay based on actual performance.

A Note on the Hire

This posting is sourced through RealAd. The role itself is a direct hire into an established European product company — a permanent seat in an experienced engineering team working on the company's own automation platform. Not agency, not outstaffing, not contract consulting. The employer's name is disclosed at the first interview, once mutual interest is confirmed.

Interview Process

We respect your time. Our process is:

1. Application review (≤24h) — we read your profile and cover message. Strong fits get a short behavioral form (12–15 min) to explore work style, ownership, and past experience.
2. Two interviews (30–45 min each) — first with the CTO: technical scenarios, ownership, AI demo, your questions. Second with our tech lead: implementation details and team fit.
3. Feedback within 48 hours after each stage — pass, decline, or move-forward update. Final offers follow within 5 business days of the last shortlisted interview.

You'll know where you stand at every stage, in writing.
