Requirements

• 5+ years of web development, with a strong focus on back-end technologies, frameworks, and tools.

• University degree in Computer Science, related field, or equivalent experience.

• Proven experience designing and implementing Web SaaS multi-tenant systems.

• Expert knowledge of Transact-SQL.

• Strong expertise in back-end architecture, including performance optimization, security, and scalability.

• Solid experience building .NET Web APIs using C#.

• Experience with Azure technologies and services, such as Application Gateway, Queues, Azure Functions, and Azure B2C.

• Familiarity with Angular using TypeScript and Jasmine (front-end experience is beneficial but not the primary focus).

• Experience working in Agile Scrum development environments.

• Excellent interpersonal skills.

• Must be willing to learn new technologies and processes as needed.

• Strong work ethic and professionalism.

Responsibilities:

• Work on a performance optimization initiative for a high-volume bulk upload pipeline by redesigning the processing workflow to improve throughput and scalability. The project involved atomizing the bulk upload operation into individual entry processing tasks, allowing uploads to run asynchronously and at lower priority relative to core day-to-day system operations. This architecture ensured that large uploads would not degrade real-time platform performance.

• Following the architectural change, focused on optimizing the single-entry processing path by identifying bottlenecks, reducing processing overhead, and improving execution efficiency. Established and monitored performance benchmarks to achieve a defined throughput target measured in lines processed per minute. The work included iterative profiling, optimization, and validation to ensure the system could sustain high-volume uploads while maintaining reliability and operational stability.

Key Outcomes:

• Enabled Bulk Uploads to run without impacting primary system workloads.

• Improved processing efficiency through single-entry pipeline optimization.

• Achieved measurable throughput targets (lines per minute) through performance tuning.

• Increased scalability and reliability of the data ingestion workflow.

We offer:

• US and EU projects based on advanced technologies.

• Competitive compensation based on skills and experience.

• Regular performance appraisals to support your growth.

• Flexibility in workspace, either remote or our welcoming office.

• Bonuses for article writing, public talks, and other activities.

• Generous time off, including vacation, national holidays, sick leaves, and family days.

• Personalized learning programs tailored to your interests and skill development.

• Free tech webinars and meetups organized by Svitla.

• Regular corporate online activities.
