You will work on a cutting‑edge intelligent assistant that automates and streamlines payroll workflows, enabling practitioners to manage payroll operations efficiently through a conversational AI experience. You will contribute across the full stack — from micro frontends and web components, through REST APIs and relational databases, to cloud‑hosted AI agents — and integrate with multiple enterprise payroll systems.

What we’re looking for

• 7+ years of experience as a Full‑Stack or Backend Engineer working with Python and/or .NET in complex enterprise environments.
• Strong experience designing and building Python‑based services, ideally including AI agents or integrations with cloud AI platforms.
• Solid experience with .NET Core for building RESTful APIs and backend services.
• Experience with modern frontend frameworks, ideally Angular, and with web components (Stencil or similar) and micro frontend architectures.
• Strong knowledge of relational databases (preferably SQL Server): writing complex queries, understanding schemas, and integrating with existing data models.
• Experience with infrastructure as code, ideally Terraform, and cloud deployments (Azure/AWS/GCP).
• Solid understanding of software architecture and distributed systems (modularization, scalability, resilience).
• Experience integrating with or modernizing legacy enterprise systems without impacting existing functionality.
• Good understanding of security best practices: identity and access management, trust boundaries, idempotency, audit trails, PII protection, feature flags/kill switches.
• Hands‑on experience with CI/CD tools (Azure DevOps, GitLab CI, Jenkins, GitHub Actions, etc.) and use of Git.
• Strong knowledge of software engineering best practices: clean code, design patterns, testing, code review, documentation.
• Professional level of English, able to collaborate with international teams – your day‑to‑day work will be in English.

What you will do

• Design, build, and maintain Python‑based AI agents using modern agentic frameworks and cloud AI runtimes.
• Develop and maintain .NET Core APIs that act as downstream services for the AI agent layer.
• Build and integrate Angular micro frontends and Stencil web components into an existing enterprise shell application.
• Work with SQL Server databases: write and optimize queries, understand and evolve schemas, and integrate with existing payroll data models.
• Write and maintain Terraform code to define and manage cloud infrastructure for the platform.
• Integrate new AI and automation capabilities into legacy enterprise payroll systems without breaking existing functionality.
• Collaborate closely with frontend, backend, AI, and infrastructure teams to deliver end‑to‑end features.
• Implement and enforce security and compliance best practices across the stack (identity, auditability, PII redaction, feature flags, etc.).
• Contribute to technical design documentation, READMEs, and the team knowledge base, helping to spread best practices and onboard new team members.
• Strong problem‑solving skills and analytical thinking, with the ability to understand complex business and technical domains (payroll, HR, compliance).
• Excellent communication skills and ability to work in multidisciplinary teams (engineering, architecture, product, operations, business stakeholders).
• Proactive attitude, strong sense of ownership, and focus on continuous improvement and automation.
• Comfortable working in agile environments (Scrum, Kanban), participating in ceremonies and contributing to team rituals.
• Experience in financial services, payroll, HR tech or other highly regulated sectors.
• Experience with event‑driven architectures and messaging systems (Kafka, RabbitMQ, etc.).
• Experience with DevSecOps tools (SAST, DAST, dependency analysis, secrets management).
• Familiarity with observability and reliability practices (monitoring, logging, alerting, SRE concepts).
• Experience with API gateways, service mesh, or service discovery tools.
• Career growth: 70% of our senior leaders started in junior positions.
• Continuous learning: access to our Technology Academy, Udemy courses, webinars, and company‑funded certifications.
• Flexibility: remote work options, flexible working policies, and social benefits (meal vouchers, transport, childcare support, private health insurance, etc.).
• Well‑being: our WeCare program supports employees in critical situations.
