On behalf of our Client from USA, Mobilunity is looking for a Senior Infrastructure/Platform Engineer 
 

Our client builds a self-hostable inference engine for pre-trained models, a wide catalog of embedding, reranking, extraction, and OCR models packed onto shared GPUs at high utilization, letting customers run them in their own cloud at a fraction of the cost of managed APIs. Search and document processing is the initial focus area, though the engine is general-purpose. The project is open source under a permissive license, holds a recognized security compliance certification, and has an actively growing developer community. The company is based in the US and has raised a sizable round from well-known venture investors.

You’ll help build the engine and own how it gets deployed and operated. That spans the deployment tooling shipped to customers (infrastructure-as-code modules, Kubernetes packaging, deployment guides, air-gapped install paths) and the internal platform behind it (build/release pipelines, multi-architecture GPU images, model caching, evaluation infrastructure). Deployments currently target two major public clouds, with additional providers, including specialized GPU cloud providers.
 

As the company moves toward offering managed clusters, you’ll help define the operational bar that makes that credible: service-level objectives, on-call practices, scale-from-zero behavior, observability, and GPU cost efficiency.
 

The team works in short, multi-week milestones with high autonomy and a workflow built heavily around AI coding agents (substantial token usage weekly). Senior engineers own requirements end-to-end across multiple projects.

Requirements:

• Experience running large-scale systems in production with a real reliability practice: error budgets, runbooks that hold up under incident pressure, data-backed capacity planning
• Background at smaller, fast-moving companies, knows when “shipped” beats “polished” and raises slipping timelines early
• Comfortable working in an agent-heavy workflow: delegating substantial work to AI agents, critically reviewing their output, and recognizing current limitations
• Strong skills in container orchestration (Kubernetes)
• Strong skills in infrastructure-as-code (Terraform or similar)
• Strong GPU infrastructure experience
• Proficiency in at least one lower-level systems programming language (Rust preferred; Go, C++, or Zig acceptable)
• Multi-cloud experience is a plus
• Open-source contribution history is a plus
   

In return we offer:

• The friendliest community of like-minded IT-people
• Open knowledge-sharing environment – exclusive access to a rich pool of colleagues willing to share their endless insights into the broadest variety of modern technologies
• Mobilunity Medical Insurance program designed to attend our teams’ needs
• Paid vacations and sick leaves, including 5 paid days per year that don’t require a sick note
• Perfect office location in the city-center (900m from Lukyanivska metro station with a green and spacious neighborhood) or remote mode engagement: you can choose a convenient one for you, with a possibility to fit together both
• No open-spaces setup – separate rooms for every team’s comfort and multiple lounge and gaming zones
• English classes in 1-to-1 & group modes with elements of gamification
• Neverending fun: sports events, tournaments, music band, multiple affinity groups

On behalf of our Client from Spain, Mobilunity is looking for a Backend Developer.

Our Client is building a new digital product focused on ticketing solutions for the entertainment industry. The platform enables users to easily discover, purchase, and manage tickets for various venues such as clubs, concerts, and other live events.

The product is designed to provide a seamless booking experience, allowing users to access events, manage reservations, and interact with venues in real time.

On behalf of our Client from France, Mobilunity is looking for a Backend Engineer.

Our client is a table management software and CRM that enables restaurant owners to welcome their customers easily. The app is useful to manage booking requests and register new bookings. You can view all your bookings, day after day, wherever you are and optimize your restaurant’s occupation rate. Our client offers a commission-free booking solution that guarantees freedom above all. New technologies thus become the restaurateurs best allies for saving time and gaining customers while ensuring a direct relationship with them.

You’ll be a core engineer on their API Platform team, the squad that connects their product ecosystem to external partners. The team owns the integrations layer that enables POS systems, marketing platforms, booking aggregators, and other third-party services to sync data reliably in real time. This is a backend-heavy role with high external impact: what you build is used directly by partner engineering teams, and the reliability of your work determines whether customers have a seamless experience or a frustrating one. The primary stack is PHP/Laravel, and you’ll also be expected to contribute to TypeScript codebases when needed.

They are looking for someone who doesn’t wait to be asked. If a sync is failing silently, you spot it and fix it. If a partner integration is fragile, you flag it before it breaks. If a new technology could solve a recurring problem better, you explore it and bring back a proposal. Proactivity is not a soft skill there – it’s a core part of the job.

Requirements:

• 5+ years of professional software development experience, with PHP/Laravel as your primary backend stack
• Deep understanding of REST API design – you’ve built and maintained public or partner-facing APIs and know what good looks like
• Experience with data synchronization patterns: webhooks, polling, event-driven architectures, retry logic, idempotency

• Comfortable working in Git-based workflows with pull requests, branches, and CI gates
• Active user of AI development tools (Claude Code, Cursor, Copilot, or similar) — you’ve integrated these into your daily workflow and are curious about pushing them further
• Upper-intermediate to advanced English proficiency

Nice to have:

• Solid TypeScript skills – you can read, write, and review frontend or Node.js code confidently
• Experience with React and/or Next.js
• Knowledge of cloud infrastructure (AWS) and containerization (Docker)
• Familiarity with OAuth2 / OIDC flows and API authentication patterns (API keys, tokens, scopes)
• Familiarity with Keycloak (B2B realm configuration, identity providers)
• Experience with message queues or event streaming (SQS, RabbitMQ, Kafka, etc.)

In return we offer:

• The friendliest community of like-minded IT-people
• Open knowledge-sharing environment – exclusive access to a rich pool of colleagues willing to share their endless insights into the broadest variety of modern technologies
• Mobilunity Medical Insurance program designed to attend our teams’ needs

• Solid TypeScript skills and hands-on experience – you can read, write, and review frontend code confidently
• Strong SQL knowledge: you write queries, understand indexes, and can reason about query performance
• Proven ability to articulate and justify architectural decisions: weighing trade-offs around scalability, maintainability, and explaining the reasoning clearly to peers and stakeholders
• Fluency with REST API design and experience consuming or building JSON integrations
• Comfortable working in Git-based workflows with pull requests, branches, and CI gates
• Active user of AI development tools (Claude Code, Cursor, Copilot, or similar) – you’ve integrated these into your daily workflow and are curious about pushing them further
• A track record of working in Agile environments with cross-functional teams
• Upper-intermediate to advanced English proficiency

Nice to have:

• Experience with React and/or Next.js
• Prior exposure to payment systems (PSP integrations, 3DS, refunds, reconciliation) or other regulated/financial domains
• Knowledge of cloud infrastructure (AWS) and containerization (Docker)
• Familiarity with Keycloak (OIDC/OAuth2, B2B/B2C realm configuration, identity providers)
• Exposure to Domain-Driven Design (DDD) or hexagonal/clean architecture patterns
• Experience with state management libraries (Mobx, Redux, Zustand, etc.)

You are the right fit if:

• You get genuinely curious about new tools, patterns, and frameworks – and you act on that curiosity
• You see AI-assisted development as a craft to develop, not just a shortcut to reach for
• You take ownership of problems rather than waiting to be told what to do next
• You bring care and rigor to a domain where mistakes are visible to users and have financial consequences
• You’re direct in technical discussions and comfortable with disagreement as part of good engineering

In return we offer:

• The friendliest community of like-minded IT-people
• Open knowledge-sharing environment – exclusive access to a rich pool of colleagues willing to share their endless insights into the broadest variety of modern technologies
• Mobilunity Medical Insurance program designed to attend our teams’ needs
• Paid vacations and sick leaves, including 5 paid days per year that don’t require a sick note
• Perfect office location in the city-center (900m from Lukyanivska metro station with a green and spacious neighborhood) or remote mode engagement: you can choose a convenient one for you, with a possibility to fit together both
• No open-spaces setup – separate rooms for every team’s comfort and multiple lounge and gaming zones
• English classes in 1-to-1 & group modes with elements of gamification
• Neverending fun: sports events, tournaments, music band, multiple affinity groups

On behalf of our Client from the Caribbean region, Mobilunity is looking for an Entra Identity Engineer.
 

Our Client is the largest bank in the Caribbean region that serves 14 countries/territories. The aim is to transform this organization from a traditional bank into a new era of fintech, leveraging the cutting-edge of current fintech offerings.

The Entra Identity Engineer implements, configures, and operates Microsoft Entra ID capabilities for workforce, privileged, application, and hybrid identity scenarios. This is a hands-on engineering role focused on secure, resilient identity operations and integration with cloud and on-prem systems.

Responsibilities:

• Implement and manage Microsoft Entra ID tenants, users, groups, roles, and directory settings
• Configure MFA, Conditional Access, Identity Protection, and RBAC policies with least-privilege and break-glass controls
• Integrate Entra ID with on-prem directories for hybrid identity (Azure AD Connect / Cloud Sync), including sync rules and writeback
• Secure service principals, managed identities, and app registrations (certificates/secrets governance, permissions consent, token lifetimes)
• Support identity components for cloud migrations and modern authentication (deprecate legacy auth, enable device compliance and SSO)
• Troubleshoot authentication, authorization, and token-related issues across apps, devices, and protocols
• Enable and support identity requirements for cloud platforms and applications (Azure, M365, SaaS, custom apps, APIs)
• Automate routine operations with PowerShell and/or GitHub Actions/Azure Automation (policy deployment, user lifecycle, access reviews)
• Implement monitoring, alerting, and incident response using Entra logs, sign-in risk, audit trails, and SIEM integrations
• Partner with security, compliance, and application teams to meet regulatory and audit requirements.

Requirements:

• Microsoft Entra ID (Azure AD) administration and troubleshooting across tenants and enterprise-scale environments
• Conditional Access, MFA, Identity Protection policy design, testing, and safe rollout strategies
• Hybrid identity patterns and tooling (Azure AD Connect / Cloud Sync, Pass-through Authentication, Seamless SSO)
• OAuth2 / OIDC token handling and claims mapping; understanding scopes, consent, and grant types
• PowerShell & automation for identity operations (MSOnline/AzureAD/Microsoft Graph modules)
• Monitoring and log analysis for identity events (sign-ins, audit, risky users/sessions, service principals)
• Privileged Identity Management (PIM) configuration, approval workflows, just-in-time access, and access reviews
• Solid understanding of RBAC, directory roles, admin unit scoping, and least-privilege design
• Working knowledge of device-based access (Intune compliance, device registration/Join, FIDO2/Windows Hello for Business)
• Microsoft Certified: Identity and Access Administrator Associate
• Microsoft Entra ID security and governance training
• Azure security fundamentals (e.g., network basics, Key Vault, Defender for Cloud)
• PowerShell automation training and scripting best practices
• Basic OAuth/OIDC protocol training and token troubleshooting

 Experience required:

• 4–7 years in identity or cloud engineering roles
• Hands-on experience with Entra ID in enterprise or regulated environments
• Experience supporting MFA rollouts and secure application access at scale
• Exposure to cloud migration or hybrid identity deployments
• Operational experience supporting identity platforms in production with on-call participation

Success Measure:

• Reduction in risky sign-ins and identity-related incidents
• On-time, low-friction rollout of Conditional Access and MFA policies
• Mean time to resolution (MTTR) for identity incidents consistently trending down
• Automation coverage for routine identity tasks and policy deployments
• Positive audit outcomes for identity controls and privileged access

In return, we offer:

• The friendliest community of like-minded IT people
• Open knowledge-sharing environment – exclusive access to a rich pool of colleagues willing to share their endless insights into the broadest variety of modern technologies
