Senior IT Solutions Architect – Mobile & Cloud Banking
About the Client
Our client is Poland’s largest financial institution and a market leader in digital banking, delivering cutting-edge services to millions of active daily users.
Please note: Optiveum is acting as the recruitment partner for this role. You will sign a long-term B2B contract directly with a reputable IT outsourcing company, dedicating your expertise full-time to this Bank's technological transformation.
About the Role
We are seeking a Senior IT Solutions Architect to co-define the target architecture for Poland’s premier mobile banking ecosystem. Operating at the intersection of product and platform engineering (50/50 split), you will design microservices-based, distributed, and cloud-native solutions designed to handle high-concurrency traffic with near 100% availability.
What You Will Do
•
Architect High-Scale Systems: Design complex, distributed software architecture and system integrations for high-volume mobile banking services.
• Bridge Platform & Product: Split your focus 50/50 between driving core Tech Platform architecture in the Foundation team and supporting dedicated domain product teams.
• Define Engineering Standards: Establish requirements for hardware, infrastructure, tech stack, service orchestration, and software development best practices.
• Integrate & Document: Model system integrations (C4/UML) and maintain complete, high-quality architectural documentation.
• Ensure Security & Performance: Partner with cybersecurity experts on access layers, OAuth 2.0/OIDC implementations, and cryptographic standards.
• Drive Data-Backed Decisions: Independently gather technical domain context across the organization to recommend and implement architectural optimizations.
What We Expect
•
Experience: 5+ years in IT solution architecture and complex system integrations.
• Domain Knowledge: Proven track record in designing architecture for mobile applications and high-availability, high-concurrency systems in the financial sector.
• Modern Stack & Practices: Practical experience with microservices architecture, Kubernetes (k8s) orchestration, containerization, and cloud CI/CD delivery pipelines.
• Platform Engineering: Solid grasp of domain-driven platform teams supporting product engineering teams.
• Security & Auth: Strong understanding of authentication/authorization protocols (OAuth 2.0, OIDC) and cryptography (digital signatures, PKI, encryption).
• Code & Modeling: Hands-on ability to model in C4/UML, read/analyze code in Java, Kotlin, or Swift, and work with Git.
• Education & Languages: Higher degree in Computer Science (or related) and fluency in reading technical documentation in English.
What is Offered
• Salary: 180 – 190 PLN/h net + VAT (B2B contract, depending on experience).
• Work Model: Hybrid (minimum 2 days/month in the Warsaw office).
• Contract Duration: 6–12 months (with a high probability of long-term extension).
• Location: Warsaw, Poland.
• Impact & Scale: Direct influence on an application powering the daily financial transactions of millions of users using a modern tech stack.

co-define the target architecture
Twoja rola będzie polegać na współtworzeniu architektury, a nie na jej samodzielnym definiowaniu od zera.
🔴
Operating at the intersection of product and platform engineering (50/50 split)
Oznacza to, że będziesz musiał balansować między pracą nad platformą technologiczną a wspieraniem konkretnych produktów, co może wymagać elastyczności i adaptacji.
🔴
designed to handle high-concurrency traffic with near 100% availability
Choć brzmi to ambitnie, 'near 100%' może oznaczać, że sporadyczne, krótkie przerwy w działaniu są akceptowalne.
🔴
Split your focus 50/50 between driving core Tech Platform architecture in the Foundation team and supporting dedicated domain product teams.
Podział pracy 50/50 może być trudny do utrzymania w praktyce, a priorytety mogą się zmieniać w zależności od potrzeb projektu.
🟡
high-quality architectural documentation
Wymaga to nie tylko umiejętności projektowania, ale także skrupulatności i poświęcenia czasu na tworzenie i utrzymywanie dokumentacji.
