Staff Backend / Database Infrastructure Engineer

Talentica is a fast-growing, YC-backed startup building critical infrastructure for the voice AI ecosystem. We are looking for a highly hands-on Staff-level engineer to lead database and backend architecture, helping us scale our platform from thousands to over 100,000 concurrent voice calls.

Key responsibilities

• Lead the design and development of a purpose-built database and indexing architecture.
• Scale the simulation engine to support high-throughput ingestion and query infrastructure.
• Develop systems for processing call recordings, transcripts, metadata, and evaluation results.
• Improve reliability, latency, and performance across the platform’s highest-load paths.
• Own projects end-to-end, from ambiguous problems to production deployment.

Requirements

• At least 5 years of production backend engineering experience.
• Hands-on experience building or core-contributing to a database, queue, indexing layer, or large-scale data system.
• Strong understanding of storage, ingestion, and query paths in distributed systems.
• Ability to discuss previous systems quantitatively, including throughput, data volume, and failure modes.
• Availability for substantial daily overlap with US working hours.

What we offer

• Opportunity to shape the technical direction of a system that serves as a long-term company moat.
• Autonomy to work in a small, senior, and highly technical team that values shipping and iteration.
• A role that remains a highly technical individual-contributor position with the potential for future leadership.
• A fast-paced environment where you can make key architectural decisions and see them implemented quickly.
