Tech Lead / Lead Full-Stack Engineer

Job Description

About Us

We build and operate internal and external software systems for data-driven business processes, CRM automation, reporting, AI-supported workflows, and digital platforms.

Our tech stack includes TypeScript, NestJS, React, PostgreSQL, Prisma, Redis/BullMQ, NX monorepos, Zoho CRM/Books, API integrations, AI/RAG systems, CI/CD, and cloud deployments.

We work with an international development team, including senior developers in India and a junior developer in Morocco.

We are looking for an experienced technical leader who can act as the right hand to the technical leadership team, take ownership of architecture and delivery, guide developers, and help us bring our engineering processes to the next level.

The Role

As Tech Lead / Lead Full-Stack Engineer, you will play a key role between technical strategy, hands-on implementation, and team leadership.

You will guide our developers, structure requirements, review technical concepts, ensure code quality, and make sure that ideas are turned into robust, maintainable, and scalable systems.

This role is ideal for someone who does not just complete tickets, but understands systems, improves processes, and takes responsibility for technical outcomes.

Responsibilities

Technical Leadership & Architecture

You will design and evaluate technical concepts for new systems, features, and integrations. You will focus on scalability, maintainability, security, and pragmatic technical simplicity.

You will work closely with management and internal stakeholders, translate business requirements into clear technical tasks, and ensure that solutions are not only functional in the short term, but sustainable in the long term.

You will support architecture decisions in areas such as:

1. Backend architecture with NestJS and TypeScript

2. React frontends and internal tools

3. PostgreSQL data models and Prisma

4. CRM/ERP integrations, especially Zoho

5. Microservices, queue systems, and background jobs

6. AI-supported workflows, RAG systems, and automation

7. CI/CD, deployment processes, monitoring, and logging

Team Leadership & Delivery

You will provide technical leadership to our international development team and ensure that tasks are clear, complete, and executable.

You will review technical implementations, provide structured feedback, conduct code reviews, and make sure the team works efficiently and according to shared engineering standards.

You will help us to:

1. Technically guide and challenge senior developers

2. Coach and support junior developers

3. Specify technical tasks clearly

4. Translate priorities into executable development plans

5. Identify technical risks early

6. Improve quality, speed, and reliability across the team

Processes, Systems & Enablement

A key part of the role is improving our engineering and IT processes.

We want to use more systems and tools to make work more transparent, enable employees, and track progress more effectively. You will help introduce practical tools and processes without creating unnecessary bureaucracy.

This includes:

1. Better use of issue tracking, documentation, and project management tools

2. Clearer requirements, acceptance criteria, and ownership

3. Improving engineering standards and development workflows

4. Establishing repeatable review and delivery processes

5. Increasing transparency around progress, blockers, and technical debt

6. Improving internal IT systems and automation

Requirements

Technical Skills

You have several years of experience as a Senior Developer, Tech Lead, Lead Engineer, or in a similar technical leadership role. You have already taken technical responsibility for more complex software projects.

You should be highly confident with:

1. TypeScript

2. Node.js / NestJS or comparable backend frameworks

3. React or modern frontend frameworks

4. PostgreSQL or relational database design

5. API design and system integration

6. Software architecture and technical documentation

7. Git, CI/CD, and modern development workflows

Experience with the following is a strong plus:

1. Prisma

2. NX monorepos

3. Redis / BullMQ

4. Zoho CRM, Zoho Books, or other CRM/ERP systems

5. AI integrations, LLMs, RAG, or agent-based systems

6. Cloud deployments, monitoring, and logging

7. Automation of internal business processes

8. Leading international development teams

Personal Profile

We are not looking for a pure coding machine. We are looking for someone with technical judgment, ownership, and leadership ability.

You should be able to:

1. Speak fluent German and English

2. Communicate clearly, directly, and in a structured way

3. Explain technical complexity in understandable terms

4. Lead developers technically and challenge them constructively

5. Make pragmatic decisions

6. Balance business goals with technical quality

7. Identify problems independently and propose solutions

8. Improve processes without slowing the team down

What Makes This Role Challenging

You will not be joining a perfectly predefined corporate setup. We have existing systems, grown processes, many ideas, and a strong need for more structure.

You need to be comfortable working with incomplete requirements and turning ambiguity into clarity.

This role is not for someone who only wants to work through well-defined tickets. It is for someone who wants responsibility, creates technical order, and helps an international team become better.

What We Offer

1. A central technical leadership role with real influence

2. Direct impact on architecture, processes, and tooling

3. Work on business-critical systems

4. International team

5. A modern TypeScript / React / NestJS environment

6. Room for automation, AI integration, and system improvement

7. Close collaboration with technical and operational leadership

Goal of the Position

The goal of this role is clear: you will help us make our technical delivery more structured, predictable, and professional.

You will be the person who brings order to technical complexity, aligns developers, protects quality, and ensures that IT systems are not only built, but actually used, maintained, and improved.
