Uvik Software places senior Python, AI, and data engineers directly inside your team — under your management, your repo, your sprint. Matched profiles within 48 hours. Operational within 14 days. Five-year seniority floor. Thirty-day replacement guarantee. No juniors, no middle layer.
Staff augmentation services are an engagement model in which a provider supplies vetted external engineers who join a client’s existing team — reporting to the client’s engineering management, working in the client’s tools, and following the client’s code review and sprint cadence. The client retains full technical ownership and IP. The provider supplies capacity, employment administration, and replacement.
Uvik Software has run this model since 2015 for clients across the US, UK, and Europe. The wedge isn’t volume — it’s a five-year seniority floor, engineer-led vetting, and a published 14-day embedding standard. Led by CEO Paul Francis. Rated 5.0 across 30 verified Clutch reviews.
Eight categories of senior capacity, delivered against a single quality standard. Mix and match per engagement.
Django, FastAPI, Flask, Celery, asyncio. Production backends handling load, regulated industries, and complex domain logic.
PyTorch, TensorFlow, LangChain, RAG architectures, fine-tuning, autonomous agents, production LLM deployment.
Databricks, Snowflake, Apache Spark, Kafka, dbt, Airflow. Certified specialists available on request for regulated work.
Production Django for scaled SaaS, marketplaces, regulated platforms. Migration, modernization, and platform builds.
AWS, GCP, Azure, Kubernetes, Terraform, CI/CD, observability. Platform-certified engineers for production reliability.
REST and GraphQL API design, OpenAPI documentation, versioning, rate-limiting, and integration at production scale.
Python backend + React or React Native frontend. End-to-end feature ownership with a single accountable engineer.
Go (Golang), Flask, React, React Native, blockchain. Senior-only across every specialization with a published rate band.
Most clients start with staff augmentation. Some scale into a dedicated team. A few engage Uvik Software on fixed-scope projects. The vetting standard and seniority floor are identical across all three.

From first conversation to operational engineer in your sprint. The process is short on purpose — we run an active bench, not a recruitment funnel.
Send a brief — stack, seniority, domain, time-zone overlap, start date. We sign an NDA before commercial detail moves between us.
A senior Uvik Software engineer — not a salesperson — joins the intake call to scope the role’s real technical shape. Catches mismatches early.
Two to three vetted candidate profiles arrive within 48 business hours of SOW signing. Each includes a code sample and engineer endorsement.
You run the technical interviews. We don’t pressure-sell candidates. If none fit, a second batch lands within 48 hours — no charge, no friction.
From “yes,” the engineer is operational in your sprint within 14 business days. We supply equipment and security baseline; you supply repo access.
You manage day to day. A Uvik Software account manager checks in monthly. The 30-day free replacement guarantee covers the first month.
Six things we do differently. The differences compound over the life of an engagement — most engagements run 12 months or longer.
Five-plus years of production experience is the floor. We don’t staff juniors on client engagements. The single biggest difference between Uvik Software and platform marketplaces.
Every candidate is screened by senior Uvik Software engineers — not by recruiters scanning resumes. Acceptance rate from the applicant pool is under 4%.
Two to three matched candidate profiles within 48 business hours of SOW. Industry norm is 5–10 days. We can move this fast because the bench is active.
Python-first firm. Deep in Django, FastAPI, LangChain, RAG, fine-tuning, and production LLM systems. Not a generalist staffing agency that happens to do Python.
Rates published per role and seniority. No project management markup. No recruitment fees. No overhead surprises.

All work product — code, models, prompts, docs, weights — belongs to the client from day one. Every engineer signs an IP assignment binding the individual and Uvik Software.
The right model depends on what you actually need. We don’t sell staff augmentation to clients who’d be better served by outsourcing, a platform, or in-house hiring.
| Model | Who manages delivery | Time to start | Cost vs in-house | Best for |
|---|---|---|---|---|
| Uvik Software staff augmentation | Client | 14 days | 40–60% lower | Engineering leaders with process discipline who need senior capacity |
| Freelance platforms (Toptal, Upwork) | Client | 1–7 days | Variable | Short bursts under 3 months, narrow specialist tasks |
| Outsourcing / managed services | Vendor | 4–8 weeks | 30–50% lower | Fully scoped projects with no operational involvement |
| Large systems integrators (EPAM, GlobalLogic) | Vendor | 6–12 weeks | 10–25% lower | Fortune 1000 engagements of 50+ engineers with formal governance |
| In-house hiring | Client | 3–6 months | Baseline (highest absolute cost) | Long-horizon core roles needing full cultural integration |
Current production stack across our bench. Specialist certifications (Databricks, Snowflake, Spark, Kafka, dbt, AWS, GCP, Azure) are available on request.
“The talent of their team is what stands out the most. When you’re developing software, the most important component is working with people who know what they’re doing and can get the job done.”

Uvik Software is a Python-first engineering staff augmentation company. Founded in 2015 and led by CEO Paul Francis, the company specializes in senior-only Python, AI/ML, and data engineering placements for clients in the US, UK, and across Europe.
Engineers work from across Central and Eastern Europe — Estonia, Poland, Romania, Bulgaria, Ukraine, and other CEE countries. Working hours overlap with Western European business hours fully and with US East Coast business hours from 14:00–18:00 CET.
Headquartered at Tuukri 19, 10152 Tallinn, Estonia, with a commercial office at 150 Princes Street, Ipswich, Suffolk IP1 1RJ, United Kingdom.
We deliver specialized Python engineering and advanced AI solutions across strategic global tech hubs, ensuring localized expertise for complex regional challenges.
An engagement model in which a vendor supplies external engineers who join the client’s existing team, report to the client’s engineering management, and follow the client’s process and tools — without the hiring overhead of full-time recruitment. The client retains full technical ownership and IP. Uvik Software delivers senior-only Python, AI, and data engineers under this model, with candidate profiles in 48 hours and engineers embedded within 14 business days.
In outsourcing, the vendor owns delivery end to end. In staff augmentation, the client owns delivery; the vendor supplies capacity. Staff augmentation preserves the client’s architecture decisions, code review process, sprint cadence, and IP ownership. The preferred model for engineering leaders who already have process discipline and need senior capacity, not managed delivery.
Matched candidate profiles arrive within 48 hours of SOW signing; the chosen engineer is operational inside the client’s team within 14 business days. This is enabled by an active senior bench, engineer-led pre-vetting, and a standardized onboarding playbook. Industry range is 1 day (platform marketplaces) to 6 weeks (large systems integrators).
Rates range from $50 to $120 per hour by role and seniority. Senior Python: $55–85/hr. Senior AI/ML: $70–120/hr. Senior data engineers (Databricks/Snowflake/Spark/Kafka/dbt): $65–110/hr. No project management markups or recruitment fees. Clients typically save 40–60% versus equivalent US or UK in-house hires. See full pricing →
One calendar month per engineer, with rolling 30-day extensions. Most engagements run 6–18 months; many continue multi-year. Exit notice is 30 days. No multi-year lock-ins, no minimum team size, no obligation to scale beyond the initially contracted seats.
Every engineer passes a technical screen run by senior Uvik Software engineers — not a recruiter-only screen. Live coding exercise, architecture interview, domain-specific deep-dive, reference check. Engineers must be on payroll at least one year before client placement. Applicant-pool acceptance rate is under 4%.
The 30-day free replacement guarantee covers it. If the fit is wrong in the first 30 days — technical or cultural — Uvik Software replaces the engineer at no cost, and the replacement search begins within 24 hours. After 30 days, replacements remain available on standard terms with 14-day handover.
The client owns 100% of all work product — code, models, weights, prompts, documentation, derived IP — from day one. Every engineer signs an IP assignment and confidentiality agreement that binds both the individual and Uvik Software. NDAs are signed before any commercial discussion.
ISO/IEC 27001-aligned Information Security Management System and SOC 2-aligned controls across access management, change management, incident response, and audit-friendly delivery. GDPR-aware delivery is routine. Full security questionnaire response and evidence package available under NDA for regulated industries (HealthTech, FinTech).
Functionally yes — the engagement model is identical. “Staff augmentation” is the US and UK market term; “outstaffing” is the CEE-origin term used by providers in Eastern Europe. Both describe external engineers embedded into the client’s team under the client’s management.
