LiquidLabs

We’re building a real-time AI App Builder.

The system architecture and core algorithms are already defined by a Principal Architect.

Frontend is handled by a separate team.

We’re hiring a Senior Execution Engineer, someone who specializes in turning complex backend designs into production-grade code.

This role values precision, correctness, and reliability over architectural creativity.

Your Mission

• Implement the designed architecture faithfully
• Build high-performance streaming endpoints

• Run non-blocking background pipelines:

   

  • billing (token counting)
  • versioning
  • persistence
  • analytics

   

• Ensure correctness under:

   

  • client disconnects
  • retries
  • concurrent requests

   

• Translate diagrams and specs into clean Node.js + TypeScript code

Critical Mental Model

We explicitly separate:

• Request lifecycle (HTTP connection)
• Workflow lifecycle (business logic)

Client disconnects must not:

• cancel persistence
• corrupt state
• leak memory

Candidates who naturally reason in this model will feel at home here.

Tech Requirements

• Strong Node.js + TypeScript
• Web Streams API
• Abort handling & cleanup
• PostgreSQL (schemas, constraints, migrations)
• Concurrency awareness (race conditions, idempotency, immutability)

Runtime Reality

• Next.js 14 App Router
• Some workloads run outside Next.js in long-running Node services
• Experience with Docker / VPS / cloud runtimes is a plus

Nice to Have

• Background job systems
• Streaming infrastructure
• Durable workflows
• Billing or analytics pipelines

We are creating the future of software development: a system that generates and executes applications from natural language in real-time.
 

Backed by a team of ex-FAANG engineers, we are moving fast. Our MVP is nearly ready, and we need a Senior Node.js Engineer to speed up and cross the finish line and scale.
 

The Mission We need clean, rapid execution. We're build ingthe engine that powers real-time AI generation.
 

The Tech Stack & Challenge

• Core: Node.js + TypeScript (Production grade).
• Streaming: Building robust streaming APIs (handling real-time token generation).
• Resilience: Managing concurrency, client disconnects, and heavy background workflows (analytics/billing).
• Database: PostgreSQL.
   

Who You Are

• You have deep experience with Async/Streaming systems (Web Streams API is a plus).
• You understand the difference between a request lifecycle and a background process.
• You write code that handles memory leaks and abort signals gracefully.
• You are a "doer", you want to translate diagrams into working code, fast.
   

If you are a senior dev who loves correctness, performance, and shipping fast, you’ll feel at home here.
 

Interested? Please send a short note with:

1. Your experience with Node.js streaming.
2. An example of how you’ve handled complex concurrency or background jobs.

We’re hiring a Web Designer to join our team and help us deliver polished, high-quality design work in a fast-paced environment. You’ll be working on a variety of web projects; creating layouts, improving existing pages, and supporting ongoing design needs as priorities shift.
 

What we’re looking for:

• Strong web design skills (landing pages, marketing sites, product pages, etc.)
• Ability to work quickly without sacrificing quality or attention to detail
• Confidence working with feedback and making iterations efficiently
• Good visual taste: typography, spacing, composition, and consistency
• Clear communication and reliability with deadlines
   

Nice to have:

• Experience with Figma (or similar tools)
• Understanding of responsive design and basic UX principles
• Familiarity working with developers and handing off designs
   

How to apply:
Please attach your portfolio or include a link to it in your application (dribbble/behance/personal site, anything is fine). Applications without a portfolio won’t be considered.
