Trusted by teams across Europe
Staff augmentation is the fastest way to add senior engineering capacity without taking on permanent headcount. We provide vetted Polish engineers who join your team, work in your stack, follow your code review process, and report to your engineering manager. No agency layer between you and the engineer. Week-to-week billing, no exit fees, no parallel commitment to other clients while engaged with you.
| Model | Team size | Who manages daily | Commitment | Best for |
|---|---|---|---|---|
| Staff augmentation (us) | 1 to 3 | You | Week-to-week | Filling capability gap fast |
| Dedicated team | 3 to 15 | You set strategy, our tech lead executes | Month-to-month | End-to-end product ownership |
| Project-based agency | 3 to 8 | Agency PM | Fixed scope, fixed price | Defined deliverable, no scope drift |
| Freelancer (Toptal, Upwork) | 1 | You | Hourly, no SLA | One-off task, prototype |
Honest take: staff augmentation wins when you have strong internal engineering leadership and need 1 to 3 specialists for 3 to 18 months. If you need a full team owning a product end to end, see dedicated development team. For fixed-scope MVP, see MVP development.
Augmentation wins when there is a clear capability gap and strong internal engineering leadership. Pattern across recent engagements: post-Series B US/UK companies plus EU enterprises with sprint-based capacity needs.
Discuss your gap →2 senior DevOps engineers embedded for 9 months while internal team focuses on feature velocity. Then 1 stays as full-time hire post-engagement.
Existing team of 6 needed Stripe, Adyen and PSD2 expertise on a 12-month roadmap. Our 2 engineers worked alongside their team, owned payment integration end to end.
SAP integration project required 3 senior backend engineers. Internal team led architecture, our engineers shipped integration code, with code review by their staff engineer.
Founder needed senior technical leadership while recruiting full-time CTO. Our architect set up CI/CD, code review process, hiring rubric, then transitioned to incoming CTO.
1 senior FHIR-experienced engineer for 4-month Epic integration project. Worked alongside their internal team with weekly review by their CISO and HIPAA officer.
Single sign-on to your Slack, GitHub, Linear/Jira, Notion. Communicates as part of your team, not as external vendor.
9 to 10am EST or your preferred slot. Reports to your engineering manager, not to us. Sprint planning and retros included.
Coding style, branch strategy, PR template, test framework, all yours. We do not impose ours.
1-on-1s with your manager. Performance reviews follow your process. We do not run a parallel HR layer.
PRs reviewed by your senior engineers using your standards. We do not bypass your quality gate.
While engaged with you full-time, our engineer is dedicated to your product only. No moonlighting, no shared time.
All-inclusive hourly rates depending on stack and seniority. Week-to-week billing, no minimum commitment, 1-week notice for off-board. For deep-dive on Polish developer rates and TCO, see cost of hiring Polish developers.
Senior backend or full-stack engineer at $65 to $80 per hour, 160 hours per month. Right for adding focused capability without full team.
Pair of senior engineers, often complementary skills (1 backend, 1 frontend, or 1 full-stack, 1 DevOps). Right for sustained capacity addition.
Small embedded pod. Often used to launch a new product line or own a vertical inside a larger product. Internal tech lead coordinates.
What stack, what gap, what seniority, what timeline pressure. We confirm fit and propose candidate profiles. If we are not the right fit, we say so.
We maintain 200+ pre-screened senior engineers. We send you 2 to 3 candidate CVs matching your stack within 48 hours. Each CV includes years of experience, recent projects, and code samples.
You run your standard interview process. Technical screen, system design, culture fit, references. We do not push candidates. You can reject all and we propose new ones.
MSA plus SOW signed. We invoice weekly or monthly. You provision Slack, GitHub, and tool access. Selected engineer joins your environment.
Standup attended. First PR opened. Pairing with your senior engineer for context absorption. By end of week 1 productive on first ticket.
Joining your Slack, attending your standups, opening PRs in your repo, reviewed by your senior engineers. We handle laptop, benefits, tax compliance and HR. You manage scope, priorities and code review.
Week to week billing, 1-week notice for off-board. After 6 months, no-fee conversion path if you want to hire permanently.
See full case studyStaff augmentation means 1 to 3 senior engineers embedded in your existing team and managed daily by you. Dedicated team means 3 to 15 engineers working as a unit with their own tech lead, reporting to you on a monthly cadence. Augmentation fills capability gaps fast (2 to 3 weeks). Dedicated team is for end-to-end product ownership over 6 to 24 months. See dedicated team page.
We are. The engineer signs a contract with Hauer Power (B2B contract under Polish law most often). You receive an invoice from us, we pay the engineer directly. You do not need a Polish entity, EoR or local payroll provider. We handle laptop, benefits, tools, tax compliance and HR.
Yes, after 6 months of continuous engagement we offer a no-fee conversion path. Before 6 months a buy-out fee applies (1 to 2 month rate, depending on tenure). We do not lock engineers into non-compete clauses that would block your hire.
Tell us. Replacement at no charge if performance issue, with 1 to 2 week paid handover. Most replacements happen within 2 to 3 weeks from your decision.
