Software Engineer (L2)

See yourself at Twilio

Join the team as Twilio’s next Software Engineer (Fullstack), L2.

About the job

This Full Stack Software Engineer (L2) role is focused on delivering scalable capabilities in the Phone Numbers domain powering how customers search, buy, provision, configure, and manage numbers globally. You’ll help build products that developers love and are fast to adopt, easy to understand, and dependable at scale. You’ll own end-to-end experiences across modern, responsive UIs and the backend systems behind them, building low-latency APIs and services designed for high throughput and operational reliability. You’ll be part of a team that values clean architecture, pragmatic iteration, and engineering excellence.

We’re entering a stage where platform maturity and speed both matter. You’ll help evolve core Phone Numbers experiences, reduce friction in onboarding and provisioning, and ensure our systems perform under real-world traffic while still shipping features customers can feel.

Responsibilities

• Collaborate with Product, Design, and Engineering to brainstorm, scope, and deliver new customer-facing capabilities

• Design, build, and maintain highly available, scalable backend services that perform reliably under real-world traffic

• Build lovable, accessible UI experiences that are intuitive, performant, and maintainable

• Continuously improve performance, reliability, and maintainability for services that power key products and drive meaningful business impact

• Own production outcomes: contribute to SLA/SLO goals, participate in on-call rotations, drive incident resolution, incorporate customer feedback, and participate in blameless postmortems

• Demonstrate strong engagement in the team setting through design reviews, code reviews, documentation, and collaboration that raises engineering quality across the stack

Required:

• 3+ years of experience building and operating mission critical user facing production systems in a distributed environment including on-call/incident response, SLA/SLOs & observability

• Proficiency in object oriented programming language such as Java and familiarity with common frameworks in that ecosystem

• Experience building modern web UIs using React + TypeScript (or equivalent), including integrating with APIs and maintaining component-based frontends

• Experience with datastores (relational like MySQL/Postgres and/or NoSQL), including data modeling, indexing and performance/debugging fundamentals

• Familiarity with scalable architecture patterns (caching, background jobs/queues, rate limiting) and reliability practices (timeouts, retries, monitoring/alerting)

• Strong cross-team communication and collaboration skills; comfortable giving/receiving feedback in an Agile environment

• Knowledge of SDLC best practices across build, test, release, and operation (code reviews, testing, CI/CD)

• Bachelor’s degree (or equivalent practical experience)

Desired:

• Experience with event streaming/messaging systems (e.g., Kafka, Pub/Sub, SQS) and asynchronous processing patterns

• Familiarity with additional languages commonly used in web stacks (e.g., PHP) and/or Node.js services at scale

• Experience using AI-assisted development tools (e.g., GitHub Copilot, ChatGPT/Claude/Gemini) to accelerate coding, debugging, test generation, and documentation, with effective prompting and careful evaluation of outputs (correctness, security, and bias) before use.
