You will turn product and engineering goals into practical designs, implement critical functionality, and carry improvements through testing, deployment, and production operation.\n\nYou should enjoy understanding how components work together, exploring unfamiliar codebases, and tracing problems beyond the boundaries of a single service. The role combines broad technical judgment with the ability and motivation to go deep into implementation details.\n\nAgentic AI development is central to how we work. We value engineers who use AI agents to expand what they can investigate and deliver, while personally understanding, reviewing, and verifying the systems they build.\nOwnership and Delivery\nTake responsibility from problem definition through implementation, production adoption, and ongoing operation.\nShow initiative: identify gaps, gather context, propose practical solutions, and move work forward with appropriate coordination.\nWork through ambiguity and setbacks, surface blockers early, and follow through on commitments.\nBalance speed with quality, explain tradeoffs, and verify that the result solves the intended problem.\nRemain accountable after release: investigate failures, incorporate feedback, and improve reliability and maintainability.\nShare knowledge and credit, seek input from component owners, and strengthen the team's ability to deliver.\nResponsibilities\nDesign across component boundaries. Translate ambiguous needs into clear designs, evaluate tradeoffs, define interfaces, and consider the effects on the wider system.\nBuild robust server-side software. Implement and improve services with appropriate correctness, performance, scalability, security, and operational visibility.\nInvestigate end to end. Follow requests, data, and failures across components identify root causes and work with component owners to deliver lasting improvements.\nRapid AI-assisted prototyping. Use AI tools to quickly build working prototypes, compare approaches, and validate technical feasibility before developing promising ideas into production-quality software.\nMove between design and code. Prototype approaches, write critical implementation code, review changes, and validate assumptions through tests and measurements.\nUse AI agents effectively. Break work into clear tasks, supply relevant context and constraints, review generated changes, and verify behavior including failure scenarios.\nLearn unfamiliar systems. Use code, documentation, experiments, AI tools, and collaboration to become effective across languages and codebases.\nEvolve software thoughtfully. Improve maintainability and delivery speed while managing compatibility, rollout, and operational risk.\nContribute across the stack. Work with APIs, client integrations, and user interfaces when needed to deliver a complete outcome.\nProvide hands-on technical leadership. Communicate decisions, coordinate across teams, mentor peers, and help others deliver.\nRequired Experience\nSubstantial hands-on software engineering experience, with demonstrated ownership of production systems and meaningful technical decisions.\nStrong system design skills: the ability to reason about interfaces, dependencies, data flows, scalability, reliability, security, and maintainability across multiple components.\nDeep backend engineering skills in at least one relevant language (Go, Rust, Node.js/TypeScript, Java, etc), including effective debugging and performance investigation.\nPractical understanding of distributed systems, concurrency, asynchronous communication, data consistency, persistence, and failure recovery. Experience with databases, caching, cloud platforms, containers, and messaging technologies such as Kafka, NATS, or comparable systems is valuable.\nExperience with automated testing, deployment, observability, and production troubleshooting.\nPractical use of AI coding agents for substantial engineering work, with the ability to explain decisions, identify mistakes, and independently verify results.\nCuriosity and demonstrated initiative to learn unfamiliar technologies and investigate beyond a single component or specialty.\nClear communication and effective collaboration across engineering teams.\nPreferred Experience\nProduction development in Rust or Go.\nFull-stack delivery or meaningful work with client applications, SDKs, or modern frontend frameworks.\nImproving systems under demanding availability, latency, throughput, or cost constraints.\nModernizing existing software and delivering changes across multiple components or teams.\nEvent-driven systems using Kafka, NATS, RabbitMQ, or comparable technologies.\nContact center, telecommunications, or other real-time enterprise applications.\nAI-enabled application development involving tool integration, orchestration, or evaluations.\nEducation\nBachelor degree or equivalent experienceFooter\nApplicants must be currently authorized to work in the United States without the need for visa sponsorship now or in the future.\n\nAvaya is an Equal Opportunity employer and a U.S. Federal Contractor.
