Staff Augmentation Process
You tell us the gap, and we take the time to confirm and sharpen the requirements, so the search targets the right fit from the start.
The Monterail lead runs the technical interview against your brief and screens every candidate before you see them.
You meet three or four people, each with the lead's written note on why they fit.
Once you choose someone, we finalize the contract and onboarding begins: setting up access and bringing your specialist into the codebase.
Depends on your urgency and developer's availability.
You pay for the hours that the people you choose actually work. There is no separate placement fee.
A Master Services Agreement with a Statement of Work per role, B2B and under NDA. Each specialist is added by appendix, so terms stay flexible from role to role.
No minimum engagement. Scale the team to the work. Most roles run full-time for three, six, or twelve months.
You own the roadmap and the daily direction. We handle pay, time off, feedback, and growth, so you get the capacity without the management overhead.
Specialists across Europe and beyond, working in English with several hours of daily overlap with your team. EU-only staffing available on request.
Monterail Tech leads
Each tech lead owns the process from scratch, runs the interviews in their specialty, and puts their name behind who they place.
Ula is an Engineering Manager and IT & Product Consultant at Monterail, with a full-stack background across Ruby, Node.js, and React. She previously served as CTO at EL Passion.
Maciej is a Senior Frontend Developer and AI Expert at Monterail, specializing in React.js and Next.js. He leads AI initiatives by helping clients integrate AI technologies into their products.
Expert skillset
Mid- to senior-level, experienced enough to take direction from your tech lead and run with it. We've been building in these stacks since 2010, so we judge a candidate's skill in them firsthand.
Beyond the core, we also source niche and hard-to-fill stacks that are slow and expensive to hire for elsewhere.
The person who vets your hire has shipped software for years and knows the role from the inside, so the assessment is grounded in how the work actually gets done.
Some roles and stacks are slow and expensive to hire for, because judging the skill takes an engineer who has done the work. That is who runs our vetting, so we place the specialists others struggle to source, even on an urgent timeline.
A single Monterail contact stays with you for the whole engagement, so you are not re-explaining context or chasing an account manager after the contract is signed.
We match on skill rather than geography, so you draw on a wider pool than any single country offers. When an engagement calls for it, we staff entirely from within the EU, under GDPR. Either way, you decide where your team sits.
Monterail grew its Go and QA team alongside Flink's own, as the quick-commerce startup opened new markets almost weekly. Adding a warehouse went from an engineering project to a routine operations task, and the backend kept pace as Flink reached 10 million customers across 60+ cities.

Bottimmo needed to migrate a nearly 500-component Vue 2 app to Vue 3, a scale few teams take on lightly. As an official Vue partner, Monterail started with a scoped estimation, then staffed a senior and a mid-level developer matched exactly to the requirements. The team also drove Bottimmo's AI initiatives, completing the full migration in under 6 months.

MindMics needed to know whether their iOS-proven health platform could extend to Android. Monterail embedded an Android developer for feasibility research on GAIA and BLE, while building the core app. The R&D surfaced tech risks and documentation gaps early, letting MindMics sharpen its roadmap and ready the app for its first Android users.

Technical support and development for connected, app, and high-tech concepts is particularly valuable for us. Monterail got the job done well, the brief was met, and the prototypes work.

We moved from reactive scheduling to proactive, data-driven decisions. The ability to see a prototype in one day and scale it to an enterprise-ready solution so quickly was a game-changer for our resource management.

Our customers love Monterail's design. They praise the app for being performant and super-slick. I wouldn't hesitate to introduce Monterail to anyone.

It's a way to extend your team with external specialists who work under your direction, inside your tools and processes, for as long as you need them. You add the exact skill the project needs without a permanent hire, then scale back down when the work is done.
Staff augmentation adds individual specialists to your existing team, where they work as part of it, in your process and your tools. Outsourcing hands a whole project or function to an external vendor who plans and delivers it separately. The choice comes down to what you need: extra hands inside your team, or a finished piece of work delivered by someone else.
All developer roles at mid- and senior-level across the software development process, plus product designers, project managers, and quality assurance specialists. Our core stacks are the ones we build in-house: Flutter and React Native for mobile, Vue.js, Ruby on Rails, and Node.js for web, plus AI/ML. We source niche or hard-to-fill stacks through our vetted partner network.
Our tech leads run technical interviews with every candidate, so the assessment focuses on how they perform in real work. You meet only the three or four people who hold up, each with a written note on why they fit, and you can run your own technical check on any of them.
The rate depends on the role, the seniority, and whether it's full-time or part-time. You pay for the specialist's time at an hourly or day rate, all-inclusive, with no separate placement fee. Sending us a brief is free and non-binding, and you get a specific quote before you commit to anything.
Our specialists work from across Europe and beyond, in English, with several hours of daily overlap with US, UK, and EU teams. If your requirements call for it, we can also staff the engagement entirely from within the EU, under GDPR.
