Svitla Systems Inc. is looking for a Lead Java Engineer for a full-time position (40 hours per week) in Ukraine. Our client is a Canadian courier and package delivery company. The company delivers nearly 500,000 parcels daily across Canada thanks to a technological platform offering more than 3500 optimized routes to independent delivery employees. The company’s services are provided via a digital order tracking platform that lets suppliers and logistics service dealers accept bulk orders, track parcel delivery routes, check and communicate shipment details, manage bills and invoices, and fasten the cargo shipment processes by partnering with certified transporters, enabling clients to request and enjoy secured transportation of their parcels and cargos by being able to track them in real-time. The client’s customers include Amazon, Pitney Bowes, and Landmark Global, which handle shipping for Etsy and eBay.

About the project:

The squad is currently working on a third-party system that the client doesn’t own but relies on, as it is the company’s backbone. However, the plan is to rebuild this system, so they want the internal team to focus on deploying the new system. The team continues working on the legacy system. They expect the business to continue sending new features, bug fixes and changes to handle. The project is not “very clean”. It means there are no automated tests and no plan to add more (it is challenging to add the first test, which would require lots of investment). This means that the developers must be able to navigate the code without a safety net. There is also minimal documentation in the code, and most of the knowledge is transferred by developers. It is a big monolith performing lots of work. There is a UI portion, but no UI is expected to be coded; they simply disable parts of the UI to prevent users from making big, long queries.

Requirements

• 6+ years of experience in software development.
• Experience in tech-leading
• Strong knowledge of Java and system design.
• Knowledge of Groovy.
• Solid experience with Hibernate.

Responsibilities

• Lead the squad of 3 senior engineers.
• Write high-quality Java code and resolve technical issues.
• Thoroughly test the code written with unit, integration, load, and end-to-end tests.
• Develop innovative, scalable, secure, and fault-tolerant software solutions.
• Contribute to software design and alignment with long-term goals.
• Create and maintain technical documentation.
• Guide the team in making technical decisions and staying updated.
• Ensure software quality and adherence to standards.
• Participate in project planning, tracking progress, and managing risks.
• Facilitate team communication and bridging gaps.
• Take responsibilities for other duties as assigned, related to system integration and software
