Position Overview

Join Avaya’s Agent Experience team to build the agent desktop for Avaya Infinity, our flagship enterprise omnichannel contact-center platform. The desktop brings together real-time voice and digital interactions, integrated modules, extensions, and CRM capabilities into a reliable agent workspace.

You will deliver features across a React/TypeScript desktop and Go/Rust backend services, applying strong computer science fundamentals to state management, client/server coordination, messaging, and media integration. Our platform serves deployments from small environments to large enterprises, running on Kubernetes across Azure AKS and Google GKE, with on-premises support planned.

We expect hands-on experience with agentic AI development, using tools such as Codex or Cursor to move from rapid prototypes to well-designed, verified production software.

Responsibilities

• Build features across the agent desktop and supporting services, partnering with product, design, and platform teams.

• Define where state belongs and how clients and services synchronize, recover from failures, and preserve user work.

• Design session and media ownership across tabs, browsers, virtual desktops, and embedded clients, preventing conflicting actions.

• Develop real-time communication and media integrations, selecting appropriate APIs, streaming, and messaging patterns.

• Build extensibility and CRM integrations with clear contracts for lifecycle, shared context, permissions, and failure isolation.

• Make observability part of the experience through connection and media health indicators, useful diagnostics, and correlated client/backend telemetry.

• Deliver accessible, responsive, secure applications with meaningful tests covering critical workflows, concurrency, and recovery.

• Use AI agents effectively, contribute to architectural decisions, mentor engineers, and support production systems.

• Required Experience

• Computer science fundamentals and first-principles reasoning: strong understanding of concurrency, networking, and distributed systems, with the ability to explain tradeoffs and turn designs into production software.

• Full-stack delivery: experience building complex, stateful applications across clients and services. Hands-on backend experience, with Go/Rust proficiency or demonstrated ability to become productive quickly.

• Front-end engineering: strong React, TypeScript, and browser fundamentals, including asynchronous behavior, component architecture, state synchronization, performance, and accessibility.

• Real-time reliability: experience with persistent connections, concurrent sessions, state ownership, event ordering, idempotency, reconnects, and partial failures.

• Integration design: experience with APIs, event-driven interfaces, modular applications, authentication and authorization, and working knowledge of databases and caching.

• Observability and quality: ability to investigate issues across browser, network, and service boundaries using logs, metrics, traces, and automated tests.

• Cloud delivery: experience with automated build and deployment pipelines, containers, and working familiarity with Kubernetes.

• Collaboration and ownership: ability to clarify ambiguous requirements, coordinate across teams, and own software through production operation.

• Agentic AI Development

• Prior hands-on experience with coding agents is required, along with the ability to rapidly deepen that capability.

• Work prompt-first, providing clear requirements, codebase context, architectural constraints, and verification criteria.

• Choose the right approach for the task: AI pair programming, delegated implementation, multiple agents, or rapid prototyping and spikes.

• Guide agents through implementation and testing, critically evaluate their output, and rework prototypes into production-grade designs.

• Own the correctness, security, maintainability, and performance of delivered software, following company policies for AI use.

• Preferred Experience

• Contact-center or other real-time communications applications, including voice and digital interaction workflows.

• WebRTC and browser media integration, including diagnostics for jitter, packet loss, and latency.

• Multi-instance coordination, Citrix environments, desktop extensions, client SDKs, or CRM integrations such as Salesforce.

• Production Go or Rust; WebSockets, SSE, NATS, or comparable messaging technologies.

• OpenTelemetry, AKS/GKE, and on-premises deployments.

Education

• Bachelor degree or equivalent experience in Computer Science or Engineering

• Pay Transparency

• The pay range for this opportunity is from $134,925 to $180,000 + benefits. This range represents the anticipated low and high end of the salary plus bonus for this position. Actual total compensation will vary and is based on factors such as a candidate’s qualifications, skills, and competencies.
