Full-Stack Engineer (Backend Heavy)
Experience: 4–6 Years | Function: Engineering — Product | Location: On-site
About Us
We’re building the next generation of AI-powered business software, and we’re looking for people who want to shape that future with us. With Lumen, we’re reimagining how users interact with CRM — moving beyond screens, menus and dashboards to an intelligent interface where users can simply ask AI to take actions, retrieve knowledge, generate insights and get work done. With Agent Studio, we’re enabling businesses to build, test and deploy their own AI agents for real-world workflows. And with Invorto, we’re bringing AI to voice, allowing businesses to create intelligent voice agents tailored to their customer and operational use cases.
What makes this especially exciting is the stage and scale of the opportunity. You’ll get to work on genuinely hard problems across LLMs, agents, reasoning, orchestration, voice AI, evaluation, reliability and enterprise security — not as isolated experiments, but as products used in real business workflows. You’ll have the opportunity to build zero-to-one, own meaningful parts of the product end-to-end, work closely with customers, experiment rapidly, and see your work reach production at scale.
Why join now? Because the playbook for enterprise AI is still being written. You won’t just be implementing someone else’s roadmap — you’ll help define the product, architecture and experiences that become that playbook. Expect high ownership, fast iteration, hard technical and product problems, direct customer impact, and the chance to build AI systems that have to work reliably in the real world — not just in a demo.
About the Role
We are looking for a Full-Stack Engineer with a strong backend bias to help build end-to-end product experiences across Lumen and Agent Studio. You will own features from database and API design through to the front-end experience, working closely with product and design to ship AI-powered experiences that real business users depend on every day.
What You’ll Do
Design and build backend services and APIs in Python that power core product and AI-agent features.
Build front-end interfaces and experiences that let users interact naturally with AI agents, insights and CRM workflows.
Own features end-to-end — from data modeling and backend logic to UI implementation, testing and release.
Work with product managers and designers to translate requirements into well-architected, scalable systems.
Integrate with LLM-based and agentic backend systems built by the AI/ML engineering team.
Optimize application performance, reliability and code quality across the stack.
Engage directly with customers and customer success teams to understand workflows, triage issues and inform roadmap decisions.
What We’re Looking For
4–6 years of professional full-stack engineering experience, with a clear backend-heavy skill set in Python.
Strong experience designing and building REST/GraphQL APIs, data models and scalable backend services.
Working proficiency with modern front-end frameworks (e.g., React) to build and integrate user-facing features.
Experience with relational/NoSQL databases, caching and cloud infrastructure.
Ability to move fast in a zero-to-one environment while maintaining code quality and system reliability.
Strong communication skills — this is a customer-facing role, and you will be expected to clearly articulate technical concepts, decisions and trade-offs to both technical and non-technical stakeholders, including customers.
Good to Have
Experience building features on top of LLM or AI-agent backends.
Prior experience in CRM, SaaS or enterprise business applications.
Exposure to real-time or voice-based product interfaces.
We are looking for a skilled Full Stack Developer with 3+ years of experience in Python and React.js to join our engineering team. The ideal candidate should have strong experience building scalable web applications, developing backend APIs, and creating responsive frontend interfaces.
Key Responsibilities
- Develop and maintain full-stack web applications using Python and React.js.
- Build scalable and secure RESTful APIs using Django, Flask, or FastAPI.
- Develop responsive and user-friendly interfaces using React.js.
- Integrate frontend applications with backend APIs and third-party services.
- Work with databases such as PostgreSQL, MySQL, or MongoDB.
- Write clean, reusable, and maintainable code.
- Troubleshoot, debug, and optimize application performance.
- Participate in code reviews and follow software development best practices.
- Collaborate with UI/UX designers, QA engineers, DevOps, and other developers.
- Write unit and integration tests to ensure application reliability.
- Use Git/GitHub/GitLab for version control.
