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

• Leadership skills.
• Team player, innovative and creative, able to see the "big picture" and take part in shaping the product.
• Passionate with a strong interest in staying current with industry trends and techniques.
• Excellent communication, analytical and interpersonal skills.

We offer

• Opportunity to design and develop complex integration solutions
• Stable permanent job contract
• Flexible working hours to help you keep the work-life balance and find time for your hobbies
• Partnership approach & communication respecting individual needs and employee development plan ideas
• Possibility to gain professional experience and learn from global industry experts

Про компанію

• Платформа ШІ-агентів дозволяє компаніям розгортати індивідуальні рішення на основі штучного інтелекту (такі як автоматизація документообігу, операційна аналітика та агенти штучного інтелекту) за лічені дні, а не місяці. 

Вимоги до кандидата:

• Освіта та фундаментальні знання: вища освіта в галузі Computer Science (бакалавр або магістр) з акцентом на алгоритми, структури даних та дискретну математику. Обов'язкове глибоке розуміння основ: асимптотичний аналіз (Big O, Theta, Omega), динамічне програмування, графи (BFS/DFS, найкоротші шляхи), дерева (бінарні, AVL, B-дерева), хеш-таблиці, черги, стеки та купи. Кандидати без формальної CS-освіти не розглядаються.
• Інженерний майндсет: Доведений досвід у розв'язуванні складних проблем з фокусом на ефективність, масштабованість та оптимальність. Ми очікуємо, що ви можете пояснити, чому вибрали певну структуру даних для задачі (наприклад, чому Trie краще за хеш-мапу для автодоповнення) та проаналізувати trade-offs (час vs. простір).

• Практичний досвід: Мінімум 2-3 роки в розробці, де ви застосовували CS-концепції на практиці (наприклад, оптимізація алгоритмів у production-коді). Знання мов програмування (JS, C++, Java, Python) на рівні, достатньому для competitive programming.

   

Бонуси (значно підвищують шанси):

• Призові місця на олімпіадах з програмування (IOI, ICPC, Google Code Jam, Facebook Hacker Cup) або регіональних змаганнях.
• Високий рейтинг на платформах: LeetCode (Knight+ або 2000+ rating), HackerRank (Gold+), Codeforces (Expert+ або 1900+ rating). Надсилайте посилання на профіль у резюме – ми перевіримо.
• Участь у хакатонах з фокусом на алгоритмічні задачі (наприклад, перемоги на HackMIT, AngelHack).

Важливо: Ми шукаємо тільки тих, хто має солідний теоретичний бекграунд і може довести його на технічному інтерв'ю (live coding з задачами на алгоритми). Якщо ви самоучка без формальної освіти чи досягнень у competitive programming, ця вакансія не для вас – ми не розглядаємо резюме без підтвердження CS-фундаменту. Подання: надішліть CV з прикладами розв'язаних задач (посилання на GitHub або LeetCode).
