HEDLYNER  ·  Senior Full-Stack Engineer

Part-Time Contract  ·  100% Remote

About Hedlyner

Hedlyner is B2B workflow SaaS for the live music booking industry — the operational backbone that talent buyers, booking agencies, and venue operators use to manage high-frequency, recurring live music programs at scale. The platform automates contracts, artist communications, scheduling, payment tracking, and reporting for teams running dozens to hundreds of bookings per month. Artists receive secure, invitation-based offer links and confirm electronically — no artist account required. We are a pre-revenue startup with a small distributed engineering team across Ukraine, Ethiopia, and Europe. Our stack is PHP 8.2 / Laravel (backend) + React 18 / TypeScript / Vite (frontend), deployed on DigitalOcean with Docker.

The Role

We need a Senior-level Full-Stack Engineer who can serve as a technical force multiplier for our existing team. You will own code reviews, unblock sprints, contribute architecture decisions, and fix bugs that require deep system knowledge.  This is not a junior support role; we need someone who can jump in with minimal hand-holding, writes production-quality code and can lead by example.

What You'll Do

• Review pull requests and provide substantive, educational code feedback within 1 business day of of submission
• Diagnose and fix complex backend bugs in our Laravel application (API layer, queues, payment integrations)
• Contribute to frontend work in React/TypeScript when needed — mostly component logic and API wiring
• Participate in asynchronous architecture discussions via ClickUp
• Occasionally pair with junior engineers to unblock them on hard problems

• Flag design issues early — before they become production incidents

   

Requirements

• 7+ years of professional PHP development; 4+ years with Laravel in production — you know the internals (service container, Eloquent internals, queue system, middleware pipeline)
• 3+ years React 18 + TypeScript in production SPAs — hooks, custom hooks, component architecture; working knowledge of shadcn/ui, Radix UI, and Tailwind CSS
• Demonstrable experience doing code reviews as a principal or senior engineer — not just approving, but teaching with clear explanations of trade-offs
• Fluent in DDD layered architecture: Route → Controller → Service → Repository → Model with strict layer separation; no business logic in controllers
• Strong grasp of MySQL: query optimisation, indexing strategy, migrations at scale, N+1 elimination via eager loading
• Comfortable with PHPStan / Larastan static analysis and Laravel Pint code style — our CI enforces both
• Experience with REST API design, Docker/Docker Compose, and GitHub Actions CI/CD pipelines
• Writes tests alongside implementation (TDD): PHPUnit 10 for backend feature + unit tests, Vitest for frontend unit tests
• English proficiency sufficient for async written communication (Slack, PR comments, ClickUp) — B2 minimum

• Can deliver agreed sprint milestones within the 2-week sprint window; responsive to async communication within 24 hours.

   

Nice to Have

• Elasticsearch 7.x — we use it for search; query DSL familiarity is a plus
• Laravel Cashier / Stripe subscription billing — we run subscription payments through Cashier
• HashiCorp Vault or secrets management tooling — our production environment uses Vault for runtime secret injection
• Conventional commits workflow (commitlint / Husky) — our frontend CI enforces it
• Golang exposure (one of our engineers works in Go)

• Previous work at a startup in a lead or principal capacity

   

Compensation & Logistics

• Milestone-based payment, not hours.
• Engagement: Part-time contractor. Invoiced monthly. No equity. No benefits.
• Trial: Paid 2-week trial sprint with defined scope. Payment upon sprint completion.
• Tools: ClickUp, GitHub, Twilio, Stripe, DigitalOcean, Sentry, Postman.

How to Apply

Send the following with subject line: "Senior Full-Stack – [Your Name]"

• Link to your GitHub (or GitLab) — public repos showing PHP/Laravel and React/TypeScript work
• 2–3 sentences describing the most complex system you have architected or debugged
• A short code review of this snippet (we will send it after initial contact) OR a link to a PR where you did a substantive review
• Your current availability and timezone
• Your expected sprint rate

We read every application. No recruiters or agencies, please.

LCNC Platform Experience

Experience designing and implementing drag-and-drop builders (e.g., visual editors, form builders, workflow designers) - Advantage

Experience building end-to-end low-code / no-code platforms, including visual modeling, rule engines, and runtime execution layers - Advantage.

Core Idea in LCNC Context

In an LCNC platform, end-users compose applications by dragging/dropping/recombining blocks (pre-built components with their own data schema, UI, validation rules, permissions, etc.). When a user connects a "User Profile" block with a "Billing Info" block (and maybe a "Custom Metadata" block), the platform must:

1. Dynamically compute the resulting data shape (merged schema).
2. Preserve all metadata (decorators, validation rules, OpenAPI extensions, UI hints, relations, etc.).
3. Generate runtime artifacts efficiently: TypeScript interfaces for backend services, JSON Schema for forms/validation, GraphQL types, database migrations, etc.
4. Do it at scale without exploding memory or compile time.

For a Team Lead role on a Low-Code/No-Code (LCNC) platform, this question is not just a syntax check. The interviewer is testing your architectural vision for metadata-driven development, visual modeling, and system scalability.

In an LCNC platform, you are building the blocks that other people use to build applications.

Why It Matters for a Low-Code/No-Code Platform

• Visual Schema Composition: LCNC platforms rely on users dragging and dropping blocks (e.g., combining a "User Profile" block and a "Billing Info" block). IntersectionType() is exactly how you dynamically merge those two visual schemas on the backend into a single, valid API contract.
• Dynamic Metadata Generation: Your platform must automatically generate API documentation and forms based on user layouts. You need utilities that preserve decorator metadata at runtime to achieve this.
• Performance and Memory: Creating thousands of distinct, hardcoded classes for every user configuration wastes server memory. Class composition helpers allow you to create dynamic schemas efficiently.

What to Have for this position

• 7+ years as a Full Stack Developer
• 3+ years in Backend web development in Node.Js
• 5+ years with React +Redux frontend web applications.
• 2+ years leading design and delivery
• Deep Knowledge and experience with JavaScript, TypeScript
• Experience with Databases - MongoDB
• Deep knowledge of software architecture design and REST API
• Experience owning your code quality by writing tests, automation, and monitoring dashboards
• Strong object-oriented design and development capabilities
• B.Sc. degree in Computer Science or equivalent practical experience
• Experience in SaaS or multi-tenant or cloud-based environments or scalable platforms (born in cloud or cloud native companies) - Must
• Experience in working in a foundation/platform team - Advantage
• Experience designing and implementing drag-and-drop builders (e.g., visual editors, form builders, workflow designers) - Advantage

• Experience building end-to-end low-code / no-code platforms, including visual modeling, rule engines, and runtime execution layers - Advantage

   

Personal skills

We offer

• Opportunity to design and develop complex integration solutions
• Stable permanent job contract

Про компанію

SaaS AI-платформа, яка дозволяє підприємствам налаштовувати та впроваджувати AI-рішення відповідно до своїх конкретних потреб. Платформна команда є ключовою для цього процесу — вона відповідає за інфраструктуру, спільні компоненти та внутрішні інструменти, від яких залежить вся інженерна команда.

Роль

Це інженерна позиція з впровадження з акцентом на практичну реалізацію. Ви будете займатися розгортанням, налаштуванням та інтеграцією платформи для корпоративних клієнтів, трансформуючи їхні вимоги у робочі рішення, які розгортаються в інфраструктурі клієнта.

Роль знаходиться на перетині продуктової розробки та customer success: технічно глибока, але з розумінням реальних потреб клієнтів.

Ви тісно співпрацюватимете з платформними інженерами та бізнес-командами, інколи беручи участь у бізнес-обговореннях для уточнення технічних вимог або пояснення деталей реалізації.

Чим ви будете займатися

• Впровадження та конфігурація платформи для корпоративних клієнтів
• Побудова інтеграцій між платформою та системами клієнта
• Співпраця з внутрішніми командами для розуміння вимог клієнтів і трансформації їх у технічні рішення
• Розвиток інструментів для впровадження, документації та повторюваних процесів розгортання
• Виявлення та усунення проблем під час і після розгортання

• Періодична участь у дзвінках із клієнтами для збору вимог або надання технічних консультацій
