Responsibilities

• Designing, developing, testing, and maintaining software within a .NET 4.6 monolithic MVC API and React front‑end environment.

• Building and integrating React front‑end components into existing backend API flows.
• Investigating and resolving complex technical issues, optimizing system performance, and supporting distributed components.
• Providing technical supervision and direction to other engineers on the team.
• Supporting TJ by handling day‑to‑day technical guidance, ensuring that TJ focuses on high‑level oversight rather than operational details.
• Reviewing architecture decisions with TJ, propose improvements, and drive implementation consistency.
• Ensuring developers follow best coding practices, documentation standards, and architectural guidelines.
• Helping prioritize work, clarify requirements, and unblocking engineers during daily execution.
• Acting as a point of stability for the team during active development phases.
• Leading code reviews and maintaining engineering standards across backend and frontend layers.
• Collaborating with product managers, designers, and QA to deliver end‑to‑end features.

• Experience working with monolithic architectures and gradually modernizing them.
• Solid understanding of event patterns, asynchronous processing, and scalable design practices (even within legacy constraints).
• Ability to provide technical direction and guidance to other developers.
• Experience mentoring, supervising, or coaching engineers (formal team lead experience is a plus but not mandatory).
• Ability to structure tasks, clarify technical requirements, and support daily execution to reduce the load on TJ.
• Strong ownership mindset and ability to work semi‑independently while aligning with TJ on strategic direction.
• Level of English – from Intermediate+ and above.
