The platform integrates accounting, reporting, and budget tracking into a single system, helping our client effectively scale his business.

🛠 How You’ll Contribute:

• Work closely with our designer to implement modern user interfaces using React, TypeScript, and Ant Design.
• Develop admin dashboards and management interfaces for various business operations, including CRM interfaces for marketing services.
• Build user-facing features for platform management, budget tracking, and detailed marketing analytics.
• Implement real-time updates and notifications for system status, campaign operations, and agent activities.
• Occasionally assist in maintaining backend services using Node.js/ NestJS.
• Create or modify simple APIs for internal tools and work with data models.
• Work with PostgreSQL databases to manage business data and ensure correct data flow between the server and UI.
• Collaborate with a team and participate in technical decision-making.

🎯 What Makes You a Perfect Fit:

• Good experience with Node.js and NestJS for backend development.
• Experience with REST APIs, authentication, and data validation.
• Good understanding of PostgreSQL and database design principles.
• Experience working with designers and implementing UI/UX designs.
• Experience with version control (Git) and collaborative development.
• Understanding of modern CSS/styled-components and frontend tooling.
• English proficiency for technical communication.

👍 Nice-to-Haves:

• Experience building CRM systems, fintech platforms, or marketing tools.
• Understanding of high-load systems, microservices architecture, and Docker.
• Experience with testing frameworks (Jest, React Testing Library).
• Experience with Ant Design components and theming.

 🧰 Our Tech Stack:
React, NestJS, Node.js, TypeScript, PostgreSQL, microservices, Docker, AWS, CI/CD pipelines, high-load architecture, and provider APIs.

 🚀 Hiring Process:
The hiring process is clear and concise. It starts with a 30–40 min 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 both React and Node.js. The final step is a ~30 min conversation focused on managerial topics and organizational details.

We’re Umber - a small hands-ond development team working with fintech systems and complex business platforms. We’re opening aremote Manual QA Engineer role to join our team and support two web products that are currently in active development.

About the role and projects

You’ll work across two web products for a long-term client, both currently in active development. 

One of them is a web platform for crypto traders, focused on trading logic, competitions, and internal product flows. The second one is a business platform at the intersection of ATS, HRM, and job boards, built to manage people, roles, workflows, and payouts at scale.

Until now, quality has mostly been covered by engineers. We’re now looking for a dedicated QA to bring more consistency into the process: clearer test coverage, structured checklists, and predictable regression before releases. 

The role focuses on day-to-day quality assurance: testing new features and business logic, exploring edge cases, and maintaining lightweight QA documentation.

How You’ll Contribute

• Validate core flows and calculations (amounts, balances, reporting consistency)
• Design and maintain clear test cases, checklists, and regression coverage
• Run smoke and regression checks before releases
• Log and track issues in ClickUp, following them through to resolution
• Work closely with PM and engineers to clarify requirements and keep QA documentation up to date

What We’re Looking For

• 2–3 years of experience in manual QA for web products
• Experience working with complex business logic (fintech, trading, internal platforms, etc.)
• Ability to structure QA work: test cases, checklists, and basic documentation
• Strong attention to detail and a responsible, reliable approach to work
• English level sufficient for documentation and day-to-day team communication

Nice to have: basic API testing experience (Postman / Swagger)
 

This role is focused on manual testing and quality ownership. Due to the projects’ current stage and fast iteration cycles, test automation is not part of the scope, and we’re not planning a transition into automation in the near future.

Tech & Tools

You’ll work around a modern web stack and typical delivery tooling: Node.js, NestJS, TypeScript, PostgreSQL, TypeORM, microservices, Docker, AWS, CI/CD pipelines, provider APIs. (Devs use Jest for unit tests.)

Hiring Process

• Intro call (30–40 min) with Talent Partner
• Technical interview (60–90 min) with the CTO: a mix of experience-based discussion + a short practical QA task (e.g. exploratory testing on a demo environment, or test-case / checklist design)

Terms & Benefits

• Full-time, contract-based cooperation (FOP)
• 3-month probation period
• 24 paid days off per year, plus company days off for New Year and Christmas
• Fully remote work, no time trackers
• Annual performance review
• Occasional company gifts on holidays or special occasions

Your next challenge is waiting. Let’s connect, talk about the impact we can make, and see if we’re the right fit for each other!
