About the role

As a Senior Fullstack Engineer you'll play a key role in shaping and building our product at Zenjob. Working across the full stack, including event-driven backend services and polished user-facing interfaces, you'll collaborate closely with product managers and stakeholders, set engineering standards, and mentor others along the way.

What you'll do

• Build and evolve backend services and frontend applications using TypeScript and Java, leveraging gRPC as our primary service communication protocol.
• Collaborate cross-functionally with business, product and data to deliver high-value, high-reliability features.
• Champion continuous value delivery by advocating for quality and elevating engineering practices.
• Help drive architectural and process decisions, bringing your experience to bear on choices that affect the whole engineering organisation.
• Mentor and support other engineers, fostering a culture of learning, feedback, and continuous improvement.

What you'll need

• Collaborative and communicative skills, with the ability to clearly articulate trade-offs, influence technical direction, and work effectively with both technical and non-technical stakeholders.

• Empathetic and inclusive, with a broad understanding of the different roles and functions within a product engineering team.
