Senior Software Engineer

Location: Vilnius or Kaunas (Office-Based/Hybrid)

Position Summary:

We are seeking a Senior Software Engineer to design, build, and evolve core components of iModel Cloud Sync Services. This role focuses on developing reliable, scalable cloud services that ingest, transform, and synchronize engineering data from diverse sources into the iTwin platform.

As a Senior Engineer, you will work hands‑on with distributed systems and cloud‑native technologies, contribute to architectural decisions, and collaborate closely with product managers, architects, and other engineers to deliver robust, production‑grade solutions.

Responsibilities:

Software Design & Development

• Design, implement, and maintain cloud‑based synchronization and ETL services that transform engineering data into iModels.
• Build distributed, event‑driven, and task‑oriented systems using microservices, messaging, and containerized workloads. 
• Contribute to the design of workflow orchestration mechanisms, including state‑driven execution, retries, and long‑running tasks.
• Develop services that meet performance, scalability, and reliability requirements for global, multi‑tenant deployments.

Cloud Platform & Distributed Systems

• Implement microservices and data pipelines using Azure, Kubernetes, containers, and cloud‑native primitives. 
• Follow best practices for CI/CD, zero‑downtime deployments, configuration management, and secret handling. 
• Implement concurrency control, idempotency, and conflict‑resolution patterns in distributed workflows.
• Build and maintain observability features, including structured logging, metrics, tracing, and alerts.

Data & ETL Workflows

• Develop ETL pipelines for parsing, validation, transformation, and mapping of engineering data formats.
• Implement schema management and versioning strategies for synchronization workflows.
• Ensure pipelines support deterministic execution, fault tolerance, and transactional consistency.

Reliability & Operational Excellence

• Implement resilience patterns such as retries, backoff strategies, circuit breakers, and rate limiting.
• Participate in design and code reviews with a focus on maintainability, security, and operational readiness.
• Help diagnose production issues and contribute to root‑cause analysis and continuous improvement.

Collaboration & Technical Growth

• Collaborate with architects and principal engineers on design and implementation decisions.
• Mentor junior engineers through code reviews, technical guidance, and best practices.
• Contribute to shared engineering standards, document
