Hi 🙌
We are looking for a Senior/Lead Full-Stack developer with a focus on backend (Node/Nest.js) to join us for long-term cooperation.
You will strengthen our team in developing a comprehensive CRM platform for marketing agents. This is a key operational product for managing marketing agents who buy advertising. The platform integrates accounting, reporting, and budget tracking into a single system, helping our client effectively scale his business.
If you enjoy ownership, smart challenges, and building without bureaucracy slowing you down — we’d love to connect!
🛠️ How You'll Contribute:
- Develop and implement a scalable backend for our high-load platform.
- Optimize PostgreSQL databases for massive data throughput.
- Build and scale microservices to process large volumes of marketing and analytical data reliably (Node.js, NestJS, gRPC).
- Integrate external data and analytics APIs to ingest and sync marketing data seamlessly.
- Occasionally assist with frontend tasks (React) — e.g., dashboards, data and analytics monitoring.
- Collaborate with a team and participate in technical decision-making.
🎯 What Makes You a Perfect Fit:
- 5+ years of hands-on experience building server-side solutions with Node.js and NestJS.
- Mastery of microservices and async processing (gRPC).
- Deep experience designing and optimizing scalable, high-load systems (ideally in data-intensive, analytics, or marketing platforms).
- Deep expertise in PostgreSQL—designing and tuning databases for large-scale data.
- Strong TypeScript skills and a commitment to clean, reliable code.
- Comfortable switching context when needed and supporting frontend if required (React).
- Take responsibility and promote matters independently.
👍 Nice-to-Haves:
- Experience building CRM systems, marketing platforms, or analytics tools.
- Understanding of high-load systems, microservices architecture, and Docker.
- Team lead experience or interest in mentoring others.
🧰 Our Tech Stack:
NestJS, Node.js, TypeScript, PostgreSQL, React, microservices, Docker, AWS, GCP, CI/CD pipelines, high-load architecture, and provider APIs.
🚀 Hiring Process:
The hiring process is clear and concise. It starts with a 40–60-minute intro call with a Talent Partner - an opportunity to learn more about the project, Umber, and the team, as well as to discuss the candidate’s experience.
Next comes a technical interview (~1.5 hours) covering frontend/backend parts. The final step is a ~30-minute conversation focused on managerial topics and organizational details.
