Full-Stack Developer - Sales & Marketing Technology (Contract , Remote)

OUR HIRING PROCESS:

• We will review your application against our job requirements. We do not employ machine learning technologies during this phase as we believe every human deserves attention from another human. We do not think machines can evaluate your application quite like our seasoned recruiting professionals—every person is unique. We promise to give your candidacy a fair and detailed assessment.

• We may then invite you to submit a video interview for the review of the hiring manager. This video interview is often followed by a test or short project that allows us to determine whether you will be a good fit for the team.

• At this point, we will invite you to interview with our hiring manager and/or the interview team. Please note: We do not conduct interviews via text message, Telegram, etc. and we never hire anyone into our organization without having met you face-to-face (or via Zoom). You will be invited to come to a live meeting or Zoom, where you will meet our INFUSE team.

• From there on, it’s decision time! If you are still excited to join INFUSE and we like you as much, we will have a conversation about your offer. We do not make offers without giving you the opportunity to speak with us live.

INFUSE is committed to complying with applicable data privacy and security laws and regulations. For more information, please see our Privacy Policy

Innovation is a core value of INFUSE. We bring together people who look into the future to better understand how technology will shape businesses - people who create and navigate projects with meaningful impact. We are looking for a motivated Full-Stack Developer to join our dynamic team and contribute to the successful execution of our projects.

Role Overview: build the code that powers our AI-driven sales and marketing automation products. You'll develop front-end interfaces, back-end services, and integrations that work alongside n8n workflows, taking ownership of technical projects from architecture through deployment. This role is ideal for a developer who wants to build products that directly impact revenue and sales team effectiveness.

Key Responsibilities

• Own end-to-end development of features and services, from technical design to production deployment

• Build and maintain back-end services (APIs, data pipelines, integrations) that connect with n8n workflows built by the team

• Develop clean, responsive front-end interfaces for internal tools and customer-facing features

• Integrate with third-party APIs (email providers, CRMs, AI services) and ensure reliable data flow

• Write maintainable, well-tested code following engineering best practices

• Collaborate with the automation team to define integration points between your code and n8n workflows

• Troubleshoot and optimize system performance across the stack

Requirements

• Strong full-stack development experience with hands-on work in both front-end (React, Vue, or similar) and back-end (Node.js, Python, or similar)

• Solid understanding of software engineering fundamentals: version control, testing, code review, CI/CD

• Experience building and consuming REST APIs

• Familiarity with n8n and basic experience building or modifying workflows. You should be comfortable reading, debugging, and working within existing automations

• Familiarity with AI/LLM APIs (OpenAI, etc.) and integrating them into applications

• Experience with relational databases and basic data modeling

• Self-directed problem solver who takes ownership and sees projects through to completion

Nice to Have

• Experience building products for sales or marketing teams (CRM integrations, email automation, content tools)

• Familiarity with PDF manipulation libraries or document generation

• Experience with containerization (Docker) and cloud deployment

• Background with LangChain, FastAPI, or similar AI tooling

• Comfort with ambiguity and evolving requirements in a fast-moving environment

What We're Looking For

We value ownership and follow-through over years of experience. If you're earlier in your career but can demonstrate strong fundamentals, a bias toward action, and the ability to ship quality work independently, we'd love to hear from you.
