For more than two decades, the biggest and most beloved brands have trusted Voices to find their voices and bring their projects to life.
 
Why join us? We’re on a mission to shape the future of voice, and we’re building a team that’s curious, collaborative, and passionate about making great ideas heard.
 
About the Role  
As a Senior Software Engineer, you’ll join a high-performing development organization working in cross-functional teams to design, build, and evolve modern full-stack systems that power critical workflows for our customers and internal teams. In this role, you’ll take ownership of complex technical initiatives and contribute to system architecture and design decisions within a modern cloud-based environment, helping ensure our platform remains scalable, reliable, and maintainable as it grows. You’ll apply strong full-stack engineering expertise to solve complex technical problems and deliver solutions that balance immediate business needs with long-term technical sustainability.
 
We value thoughtful engineering, steady delivery, and continuous improvement. You’ll collaborate closely with Product, Infrastructure, QA, and Support to ensure solutions are technically sound and aligned with business goals, while proactively identifying opportunities to improve architecture, tooling, and development practices. You’ll report to the Senior Manager, Application Development and be part of a team that values high standards, ownership, and pragmatic problem solving.
 
Responsibilities  
In this role, you’ll take ownership of the following key areas:
 
Application & System Development
  • Design, build, and evolve customer-facing and internal applications using modern full-stack technologies, ensuring scalability, maintainability, and long-term sustainability.
  • Lead the design and extension of applications built on modern frameworks, contributing to architectural decisions and technical direction.
  • Design and maintain internal APIs and third-party integrations (e.g., Salesforce and cloud services), ensuring reliability, performance, and secure data exchange.
  • Drive the delivery of complex product initiatives, owning solutions from technical discovery and design through implementation, deployment, and post-release evaluation.
  • Identify and address technical debt, performance challenges, and structural improvements within the systems you support.
 
Quality, Testing & Security
  • Establish and uphold high standards for automated testing (unit and integration), ensuring long-term code quality and system reliability.
  • Apply and advocate for accessibility (AODA, WCAG) and security (OWASP) best practices across projects.
  • Analyze and optimize system performance, proactively identifying bottlenecks and recommending architectural or design improvements.
  • Provide technical leadership in diagnosing complex defects and production issues, partnering with Product and Support to drive durable resolutions.
 
Engineering Practices & Delivery
  • Contribute to release planning and technical scoping, providing clear assessments of trade-offs, complexity, risk, and long-term impact.
  • Improve development workflows, tooling, and CI/CD processes to increase team efficiency and delivery confidence.
  • Participate in and elevate code review practices, providing thoughtful feedback that strengthens overall code quality and engineering standards.
  • Use AI-assisted development tools responsibly to improve productivity, maintainability, and documentation quality.
 
Documentation & Technical Collaboration
  • Document architectural decisions, APIs, and significant implementation details to support knowledge sharing and long-term maintainability.
  • Contribute to and help evolve shared libraries, internal frameworks, and design systems to ensure consistency and reusability across teams.
  • Collaborate across teams to align on technical patterns, integration strategies, and system design approaches.
 
What You Bring
We’re looking for someone who brings some or all of the following:
  • You want to ship regularly and take pride in delivering meaningful, end-to-end solutions. You approach development with curiosity, ownership, and a commitment to continuous improvement.
  • You write high-quality, maintainable code and understand the long-term impact of design decisions. Your work is well-structured, testable, documented, and backed by comprehensive automated tests that support long-term maintainability and reliability.
  • You’re comfortable working across a varied technical stack - including technologies such as PHP, JavaScript, Node.js, Python, and modern CSS - and modern architectural patterns (e.g., MVC, reactive frameworks, APIs, distributed services), and can reason about system design trade-offs.
  • You have experience designing and evolving application architecture, balancing immediate business needs with scalability, reliability, and maintainability.
  • You have experience writing and maintaining build, migration, and automation scripts to support development and deployments.
  • You have experience designing and operating applications within cloud-based environments, with a strong understanding of distributed systems patterns such as queues, background jobs, caching, and object storage.
  • You are confident diagnosing complex issues, analyzing root causes, and implementing durable solutions in production environments.
  • You can clearly articulate technical decisions, trade-offs, and risks, and collaborate effectively with cross-functional partners to drive alignment and informed decision-making.
  • You are comfortable breaking down complex initiatives into actionable steps, estimating effort, and driving work to completion with accountability.
  • You are skilled in developing full-stack solutions from scratch, creating systems that are reusable, performant, secure, and accessible.
  • You actively contribute to technical discussions, design reviews, and code reviews, helping strengthen engineering standards and shared understanding across the team.
  • You are self-motivated and capable of operating with a high degree of autonomy, taking initiative while collaborating effectively with your team.
  • You enjoy learning, solving challenging problems, and continuously strengthening your technical craft.
  • You have 5+ years experience in software engineering (with expertise in web development), and proficiency with the software development lifecycle (SDLC).
  • You earned a BS or MS in Computer Science, Software Engineering, or have the equivalent work experience.
