Senior Full-Stack / Tech Lead (Next.js, NestJS)

LenGreo is a full-cycle digital marketing & development company. We’re currently building a new social-media-driven platform — a creator–fan ecosystem similar in spirit to modern content-sharing networks, with the ability for fans to support creators financially.

We’re looking for a Senior Full-Stack / Tech Lead who can define the technical vision and lead the build of the platform from the ground up.
 

Why this role matters:

We’re designing a high-traffic, content-heavy platform with real-time and media-rich functionality. The system must be architected from day one for scalability, reliability, security, and fast iteration.

As a Senior Full-Stack / Tech Lead, you will make the core architectural and infrastructure decisions that shape how the product is built, launched, and scaled.
 

What you’ll do:

• Define and own the overall technical architecture and system design of the platform.
• Lead technical strategy and architectural decisions across frontend, backend, database, and infrastructure layers.
• Design scalable, secure, and maintainable architecture suitable for high content volume and growing traffic.
• Collaborate closely with Product, Business Analyst, Designer, and Project Manager to translate requirements into technical solutions.
• Lead technical planning for MVP and future scaling stages.
• Select and validate frameworks, tools, and third-party services.
• Prepare realistic development estimations based on approved requirements and designs.
• Own technical delivery within agreed scope and assumptions.
• Establish development standards, architecture patterns, and code quality practices.
• Guide developers, review implementations, and support team growth.
• Design and oversee CI/CD pipelines and deployment workflows.
• Lead infrastructure and environment setup for a project starting from scratch.
   

Core technology stack:

• Frontend: Next.js
• Backend: NestJS (Node.js, TypeScript)
• Database: PostgreSQL
• Storage: S3-compatible object storage"
   

Required expertise:

• Strong production experience with Next.js frontend applications.
• Strong backend architecture experience with NestJS and Node.js.
• Proven experience designing and launching complex platforms from scratch.
• Experience architecting systems for content-heavy and high-traffic applications.
• Strong experience with PostgreSQL schema and performance design.
• Experience integrating S3 or S3-compatible storage for media-heavy platforms.
• Experience designing API architecture and service boundaries.
• Experience setting up CI/CD pipelines, automated builds, and deployment processes.
• Experience with cloud infrastructure and environment setup.
• Proven experience making architecture decisions balancing MVP speed and long-term scalability.
• Experience integrating multiple third-party services and providers.
• Solid experience with technical estimations and delivery ownership.
• Strong product and systems thinking.
   

Nice to have:

• Experience with high-load distributed systems.
• Experience with media processing and delivery pipelines.
• Experience with CDNs and caching strategies.
• Experience with real-time systems (chat, notifications, streaming).
• Experience with multi-provider payment integrations.
• Experience with user-generated content platforms.
   

Engagement format

• Full-time, remote
• Long-term collaboration anticipated.|
   

We look forward to hearing from you!
