Job description

• At Talkdesk, we build the next generation of our platform using a microservices architecture and strongly autonomous vertical teams. Each team owns its services end-to-end — architecture, delivery, quality, and production readiness.
• We expect senior engineers to set the technical bar. You will make architectural decisions, challenge assumptions, and raise the quality of both our code and our engineering practices. Peer reviews, production readiness, and collaboration are non-negotiable — nothing reaches production without scrutiny.
• This role is full-stack, but frontend excellence is critical. We are looking for someone who deeply understands how systems meet users — performance, usability, reliability — and can confidently move between React-based frontends and Kotlin/Java backend services with some legacy in Ruby.
• If you enjoy owning complex problems, influencing technical direction, and delivering polished user‑facing experiences backed by solid distributed systems, this role is for you.

Duties and Responsibilities

• Take technical ownership of complex features from frontend to backend, including design, implementation, testing, and production readiness
• Design and build high-quality, scalable user‑facing applications, with strong attention to UX, performance, and maintainability
• Develop and maintain events based services and APIs that support frontend needs at scale
• Make architectural decisions and actively influence technical direction, standards, and best practices within the team
• Collaborate closely with Product, Design, and other engineering teams to ensure solutions fully meet business and user requirements
• Act as a technical reference for the team: review code critically, document architecture clearly, and mentor other engineers
• Design and implement integrations with external systems, ensuring data integrity, security, and observability
• Identify and solve complex technical challenges, including performance bottlenecks and scalability constraints
• Advocate for automated testing, CI/CD, and production excellence
• Leverage AI‑assisted development tools (e.g., coding copilots, code review assistants, test generation tools) to improve productivity, code quality, and iteration speed while maintaining strong engineering judgment, code ownership, and security awareness
• Evaluate and integrate AI‑powered solutions where they add real value to product or engineering workflows

Qualifications

• BS/MS Degree in Computer Science, Applied Math, or an Engineering area
• 5+ years of experience in Software Development, especially in cloud‑based applications
• Strong experience with the design and development of web applications
• Strong object‑oriented programming skills and experience with cloud databases
• Component design, state management, and performance optimization
• Solid backend experience with: Kotlin or Java Spring Boot, RESTful APIs and event‑driven systems
• Deep understanding of the design and development of Service Oriented Architecture (SOA, API) and Event‑driven Architectures
• Experience with microservices architecture, APIs, message brokers (Kafka, RabbitMQ)
• Experience with one or more storage technologies (e.g., PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch)
• Experience scaling global web applications
• Advocate for automated testing, continuous integration
• Familiarity with Kubernetes-based production environments and GitHub Actions–driven CI/CD pipelines, with the ability to contribute improvements and troubleshoot issues
• Passion for producing clean, standards‑compliant, secure code
• Be fearless about learning new technologies and technical approaches to application development
• Good written and spoken English
