Extend Your Engineering Team

Senior engineers who join your team and work in your Jira, your repos and your stand-ups. You keep the backlog, the architecture and the priorities. We take care of hiring, HR and replacements. The team is based in Poland and works in UK and EU business hours.

When the Roadmap Outruns Hiring

The backlog is clear and the budget is approved, but the people are not there yet. Each usual way to close the gap has a cost.

  • Local hiring takes months

    A senior role often stays open for three to six months. The release date does not move with it.

  • Freelancers come and go

    Quality varies from person to person, and the knowledge leaves when the contract ends.

  • Project outsourcing is a black box

    The work happens outside your process, so you see the result but not how it was made.

  • Team extension keeps you in control

    Engineers work inside your team, under your tech lead and your definition of done, for as long as the roadmap needs them.

How You Stay in Control

Team extension works only when nothing about the work is hidden from you. These rules apply from the first day.

  • You choose the people

    You see the profiles, run your own interviews if you want to, and approve every engineer. You also set the seniority mix, up to an all-senior team.

  • Two-week trial

    Every engineer starts with a two-week trial. If the person does not fit, you do not pay for those two weeks.

  • Your tools and your rules

    The work happens in your Jira, your repositories and your CI. Your tech lead assigns tasks, reviews the code and decides what is merged.

  • Your metrics

    Velocity and quality are measured the way you measure your own team, so the numbers can be compared directly.

  • Replacement on request

    If an engineer stops fitting, tell us. We find a replacement and organise the handover.

  • Scale up or down

    Add engineers as the roadmap grows. To reduce the team or to stop, give two months' notice.

Rates and special terms are in a one-pager. Leave your email and we will send it.

Three Ways to Extend Your Engineering Team

The format depends on how much of the delivery you want to lead yourself. Not sure which one fits? A 30-minute call is enough to decide.

  • Role augmentation

    One or several engineers with the skills your team is missing: Java, mobile, frontend, QA automation, DevOps or AI. They report to your tech lead or engineering manager.

    • A skill gap or an open role you cannot fill quickly
    • Your tech lead plans and reviews the work
    • Bridge capacity while you hire permanent staff

  • Engineering pod

    Developers and QA who take a stream of work together. You bring the product owner and the architecture, the pod brings implementation and quality.

    • You have a product manager and an architect, but not enough hands
    • A backlog that needs steady throughput, sprint after sprint
    • Part-time DevOps support alongside the pod

  • Squad

    A cross-functional team that owns one product area with agreed boundaries: its own backlog slice, its own releases, your overall direction.

    • A separate product, module or domain
    • A long horizon measured in quarters and years
    • Your in-house team stays focused on the core

  • Need us to run delivery?

    If you would rather have a team with its own project manager that estimates the work, agrees the dates with you and takes responsibility for delivery, that is a managed dedicated team.

    • No spare engineering management on your side
    • One accountable partner for delivery

Staff Augmentation That Goes Beyond a CV

Plain staff augmentation often ends when the CV is accepted. Our responsibility for the engineer lasts for the whole engagement.

  • Screened before you see a profile

    We check each engineer against your stack and the seniority you asked for, so you get a shortlist to choose from and not a pile of CVs.

  • Retention is our job

    Employment, training and career growth stay with us. The people who have learned your product have a reason to stay on it.

  • Backup and replacement

    If someone leaves or stops fitting, we organise cover and a replacement. You do not restart your own hiring.

  • Knowledge stays with you

    Code, documentation and runbooks live in your repositories. When an engineer changes, the handover is planned, and you can ask for a full handover at any time.

Roles You Can Add

In-house engineers and vetted network specialists go through the same screening. Everyone on your team is employed and managed by Smartym Pro.

  • Backend engineers (Java / Spring, Node.js, Python)

  • Frontend engineers (React, Angular, Vue)

  • Mobile engineers (iOS, Android, Flutter)

  • QA engineers, manual and automation

  • DevOps and platform engineers

Transparency, Knowledge and Security

  • Daily communication in your Slack, email and video calls

  • Code, documentation and runbooks live in your repositories

  • Knowledge-transfer plan and full handover whenever you ask

  • ISO 27001 certified processes, NDA and access rules agreed up front

  • AI tools in the workflow only within your standards, with human review

Frequently Asked Questions

Yes, those are the market names for it. The engineers work in your team and under your management, while we stay their employer. What we do not do is hand over a CV and disappear: we keep responsibility for the engineer's performance, backup and replacement.

In team extension you lead the work day to day and keep full control. In a managed dedicated team our project manager estimates the work, agrees the dates with you and runs delivery. In a project we commit to a defined scope. If you want an outcome without being involved in the backlog, team extension is the wrong model.

Often it does. Permanent hires are right for the core team, and they take months. Extension engineers cover the gap while the roles are open, then the team shrinks or stays, depending on your plan.

Typically two to six weeks from your request, depending on the stack and seniority. We tell you in our reply which profiles are available now and which need a search.

Our engineers are based in Poland, and we have offices in Warsaw and London. The working day overlaps with UK and EU business hours, so stand-ups, reviews and calls happen in real time. For teams in the US we agree the overlap window before the start.

Yes, this is where most of our work is. Our engineers have built an open banking API hub under PSD2, a trading platform, and wallet and payment apps. On a regulated product the engineers follow your access model and compliance rules and work in your tools, so the audit trail stays with you.

We provide the laptops and the workplace. You grant access to your systems under your own access model and can revoke it at any time.

One or two engineers is a normal start. The model is built for work that lasts months, not for a two-week task.

Yes, two weeks for every engineer. If the engineer does not fit, you do not pay for the trial and we propose another person.

Yes. You decide the seniority mix, and the team can be fully senior. You approve each engineer, so the level stays under your control.

You tell us and we replace the person. Backup, handover and the search are on our side, so you do not restart your own hiring.

With two months' notice. That gives time for a proper handover of the work and the knowledge to your team.

You own the code and everything produced for you; it lives in your repositories. We sign an NDA, follow your access model and work from the EU. Details are agreed before the start.

You pay for the time each engineer actually works on your project. Vacations and sick leave are not billed. The rate covers salary, taxes, equipment and our management. Rates and special terms are in a one-pager that we send by email on request.

Yes, where your policy allows it. AI assistants speed up drafts, tests and documentation. An engineer reviews and owns every change, and it passes the same CI checks as any other code.

That is recruiting, a separate service. Tell us in your request and we will point you to the right team.

Tell us which roles you need and by when

Stack, seniority and start date are enough for a request. We will come back with profiles that match.
