How quickly can an engineer start?

We confirm the start date once we have seen your codebase and agreed the role. There is no procurement process on your side.

What seniority do your engineers have?

Senior only. Every engineer has at least five years of experience and is expected to take ownership early, not to need constant management.

Who manages the engineer?

In the team-extension model, you do: they join your stand-ups, sprint planning and tools. With a dedicated team, we manage delivery against goals you set, and a technical lead role is available when your team has no internal leadership.

How is staff augmentation priced?

To scope and value, not by the clock, and always in writing before work starts. We do not publish a figure, because it depends on the role, the seniority and the duration.

What is the minimum commitment?

Engagements run on monthly contracts with a 30-day notice period. There is no long-term lock-in.

Which roles can you fill?

We fill senior Next.js and React engineers, Node.js and backend engineers, full-stack engineers, AI and LangChain engineers, and technical leads.

Can the engineer work in our time zone?

We work on CET, so our hours overlap with a standard working day across most of Europe. We join your daily stand-ups and sprint planning.

Who owns the code and who has access?

You do. Engineers work in your repository and tools, and you have direct access to the source at all times. A data-processing agreement is available on request.

IT Staff Augmentation Services | Senior Next.js Engineers

IT Staff Augmentation & Dedicated Senior Developers

Your lead developer just left mid-project, and a senior hire takes months? Our engineers, all with 5+ years of experience, join your repo, tools and sprints without a hiring process. We confirm the start date once we have seen the codebase.

IT Staff Augmentation

We add experienced engineers (Next.js, AI, mobile, DevOps) directly to your existing team, so the people who join can take ownership from the start.

Outcomes

Senior only: engineers who take ownership, not juniors who need constant management, integrated into your Slack, Jira, GitHub or Linear from day one with CET timezone overlap. Full transparency: direct access to the source and frequent progress reports.

Process

We start by defining exactly what skills and seniority you need, then present matching profiles and get you a working engineer inside your development cycle: no long procurement process.

Senior Talent as a Service

In a staff augmentation model, your velocity depends on the quality of your engineers. That is why we work exclusively with senior talent. We don't provide juniors who need constant management. You get engineers who take ownership early, write scalable code and contribute to architectural decisions, reducing your technical debt from day one.

What IT staff augmentation is

Staff augmentation means adding an experienced engineer, or a small group, to your existing team for a defined period. They work in your repository, tools and sprints, under your direction, without a hiring process on your side.

It differs from outsourcing a whole project: you keep the product decisions and the day-to-day lead, and we provide the people. Each of our engineers has at least five years of experience, and the engagement runs under a contract and, on request, a data-processing agreement.

Flexible Scaling Models

We adapt to your operational needs through two models, both with CET overlap and scoped pricing:

Team Extension: Individual experts integrated into your existing team under your leadership.
Dedicated Team: A full-scale development team (Devs, QA, UI/UX) managing projects autonomously based on your goals.
Timezone Overlap: Operating in the CET timezone, our hours overlap with your standard working day.
Rate Advantage: Engagements are priced to scope and value, not billed by the clock, typically below what comparable senior talent costs in Germany, the UK, or the Netherlands.

When staff augmentation fits, and when it does not

It fits when:

you have a committed delivery date and the team is behind
you have a permanent capacity gap but a full-time hire is not justified
your team lacks one specific skill, such as AI integration, e-commerce architecture or multilingual setup

It does not fit when you want someone to build a whole product with a fixed scope from a short description. That is project work, not team extension. It also does not fit when nobody on your side sets priorities and reviews the work. For that case we offer the technical lead role.

Technical Specialisation

We specialise in the modern stack required for high-performance digital products:

Frontend: Expert-level Next.js, React, and TypeScript development.
Backend & AI: Node.js and TypeScript (LangChain.js, Vercel AI SDK) with advanced LLM integrations.
Mobile: Cross-platform React Native solutions for iOS and Android.
Cloud & DevOps: Professional infrastructure setup on AWS and Vercel.

Direct Workflow Integration

Communication is our foundation. Our engineers become a natural extension of your internal ecosystem:

Tools: We integrate into your Slack, Jira, GitHub, or Linear workflows.
Agile Participation: We join your daily stand-ups and sprint planning sessions.
Transparency: You get frequent progress reports and direct access to the source code at all times.

Contract terms in plain words

Monthly contracts with a 30-day notice period. No lock-in.
Pricing to scope, written before work starts, not billed by the clock.
Working hours on CET, overlapping with your working day.
Code lives in your repository from the first commit, and you have direct access to the source at all times.
A data-processing agreement is available on request.

Our Onboarding Process

Speed to market is critical. Our process lets you scale up efficiently:

Needs Assessment: Defining the specific skill sets and seniority required.
Selection: We present senior developer profiles that best match your project requirements.
Integration: Technical setup and a start date we confirm once we have seen your codebase.

Roles We Fill & Typical Engagement Scenarios

Staff augmentation works best when expectations are clear from the start. Here are the specific roles we fill and how engagements typically take shape.

Roles Available:

Senior Next.js / React Engineer: frontend architecture, performance optimisation, component systems, SSR/PPR implementation
Node.js / Backend Engineer: API development, database design, third-party integrations, serverless infrastructure
Full-Stack Engineer: end-to-end feature ownership, suitable for smaller teams needing one person across the stack
AI / LangChain Engineer: RAG pipelines, agent orchestration, LLM integration, n8n automation workflows
Technical Lead: code review, architecture decisions, junior mentoring, sprint planning for teams without internal leadership

Typical Engagement Scenarios:

Scenario A. Deadline pressure on an existing project: Your team has a committed delivery date and is behind. We embed one or two engineers for as long as it takes to clear the backlog, take ownership of specific feature areas, and hand back a stable codebase.

Scenario B. Permanent capacity gap: You have ongoing work but cannot justify a full-time hire. We provide a dedicated engineer on a monthly retainer, effectively a fractional team member with full context continuity.

Scenario C. Specialist skill gap: Your team is strong but lacks a specific capability (AI integration, e-commerce architecture, i18n). We fill that gap for the duration of the feature build, then step back.

All engagements run on monthly contracts with a 30-day notice period. No lock-in.
