Freelance Associate Backend Developer Jobs (NOW HIRING)

Role OverviewAbout the role

Node.Js | Typescript | NestJs | MongoDB

Naologic is building the next generation of ERP and system-of-record platforms from the ground up - AI-natively and customizable to any industry with zero-implementation time. We are redefining how enterprise software is built, deployed, and operated at scale.

This is not a typical backend engineering role. We are looking for a Senior Backend Engineer with the mindset of a systems architect - someone who deeply understands enterprise software, ERP systems, and complex business processes.

The strongest candidates we hire think like builders: they understand why they are building something, not just how. If you don\'t have a strong opinion about how enterprise systems should work, this role is not for you.

You will be responsible for the development of backend logic, database architecture, and maintaining the best possible performance, quality, and responsiveness of our platform. You will work at the intersection of AI systems, core platform infrastructure, and real business logic — building the backbone of an AI-native ERP.

What You\'ll Be BuildingThis role sits at the visual and interaction layer of Naologic\'s platform. Your work will directly involve:

• AI Systems Work: Designing and building the backend infrastructure that powers our AI capabilities: From code generation pipelines to intelligent business logic engines.
• Core Builder AI Functionality: Building the systems that allow our AI to generate, validate, and deploy enterprise applications autonomously.
• Workspace Logic Pilot: Developing the backend logic that drives our workspace automation and intelligent workflow systems.
• Prompting & LLM Integration: Deep work with prompt engineering, RAG systems, and LLM orchestration at the platform level.
• Systems Thinking: Every feature you build connects to a larger enterprise system. You must think in terms of data flows, business processes, and system-wide implications.

Responsibilities

• Design and develop backend logic using TypeScript and NestJS.
• Create and maintain server-side application logic.
• Utilize MongoDB aggregations to handle complex data requirements.
• Architect and build AI-powered backend services including prompt pipelines, RAG systems, and LLM integration layers.
• Design event-driven systems that orchestrate complex business workflows.
• Collaborate with frontend developers to integrate frontend components with server-side logic.
• Write clean, high-quality, and testable code.
• Optimize applications for performance, availability, and low latency.
• Focus on security, compliance, and data protection for enterprise-grade systems.

Required Skills and Qualifications

• Expertise in TypeScript / NestJS.
• Expertise in MongoDB aggregations.
• Experience with ERP/CRM systems
• Experience with Node.js and common packages (e.g., fastify, jwt, lodash).
• Knowledge of integrating various data sources and optimizing for different client platforms.
• Experience with scalable Node.js applications and performance.
• Proficiency in version control using Git.
• Advanced knowledge of AI and prompting.
• RAG and prompting technologies.
• Deep understanding of enterprise software, ERP systems, business processes, compliance, and security.
• Systems thinking — the ability to reason about how components interact across a complex platform.
• Strong opinions about software architecture, backed by experience building and shipping production systems.

Bonus Skills

• Background as a systems architect or backend architect.
• Knowledge of Pulumi
• Understanding of manufacturing, supply chain, or industrial business processes.
• Experience with event-driven architectures and message queues at scale.
• Prior work with AI/ML systems in production environments.

Work ExpectationsWe are building something unprecedented, and that requires unprecedented commitment. This role demands the intensity and dedication you\'d find at other high-commitment organizations. Here is what that means in practice:

• Long hours. This is not a 9-to-5. Expect 50–60+ hour weeks as standard, with more during critical builds. We move fast and we ship constantly.
• Hard problems, every day. You will be building interfaces for enterprise workflows that don\'t have established UI patterns. This is frontier work - not landing pages.
• Ownership mentality. Every engineer at Naologic is expected to be hands-on and contribute directly to the company\'s mission. Leadership is earned by those who show initiative and consistently deliver excellence.
• This will likely be the most challenging job you have ever had. We are not interested in candidates looking for a comfortable role. We want engineers who are dead set on dedicating themselves fully to this mission.
• But it will also be the most rewarding - both intellectually and financially. You will work on problems at the cutting edge of AI and enterprise software, with direct impact on how businesses operate worldwide.
• If you thrive on visual precision, move fast under pressure, and want to build the next era of enterprise software - apply. If you struggle with attention to detail or can\'t think in component abstractions, this is not it.

Typescript, NestJS, nx.dev, MongoDB, BigQuery, Scheduling mechanism, Queues & Cache (Redis), Cloudflare Workers/Store/Ai gateway, RAG, Event driven architecture

• Work on the most challenging problems in AI-powered enterprise software.
• Direct impact on the future of how businesses interact with their operations.
• Grow into a senior technical leader at a company defining a new category.
• Competitive salary ($50k - $90k/year) based on experience and impact — top performers are compensated accordingly with frequent salary reviews for rapid advancement
• Considerable equity-based compensation
• Small team, high ownership, zero bureaucracy.
• Work alongside Co-Founders and founding engineers daily.

Interview Process

• Screening: We receive thousands of applications per role and only around 1% will be invited to complete a take-home test. We do a thorough and extensive screening before inviting candidates to the next step.
• Round 1: Take-home test — a real-world problem that tests how you think about systems, not just how you code.
• Round 2: 90 min technical panel interview, discussing the assignment in depth with Founding Engineer and both Co-Founders (representing FE, BE, Product and Design).
• Round 3: Salary and culture discussion with Co-Founder
