Senior Full Stack Engineer

About Viamo

Mobile technology is revolutionizing how organizations engage with their end users. More than 96% of the world’s population has access to a mobile phone, meaning it is now possible to reach nearly every single person on the planet. Yet 3 billion people living in emerging markets still lack access to relevant, timely, and engaging information in their local languages, and their voices remain underheard. The organizations that serve them lack the technology and capacity to reach them, and many are unaware of the power of mobile technology to meet their organizational goals.

Viamo connects individuals and organizations using digital technology to make better decisions.

Viamo is the #1 Digital Platform connecting these organizations to the Next Billion users who don't have access to the internet, and we are well on our way to meeting our goal of reaching 100 million people annually.

About the role

We are looking for a Senior Full Stack Engineer to join our growing, multinational team of engineers. We work passionately to improve the quality of life for people in lower and middle income countries through high quality digital services with human centered design bridging the gaps of commerce, education and health. All our users need is a simple mobile phone and a mobile connection to get access to the information and services they need to succeed and thrive.

As a Senior Full Stack Engineer at Viamo, you and your team will be responsible for multiple exciting projects. You will be building, maintaining, and scaling a large-scale platform that handles millions of voice and SMS interactions every month. You and your team will be innovating on and scaling GenAI and language AI voice technologies for people in low-resource languages.

What’s in it for you?

• Generous vacation (unlimited) - Yes, you heard that correctly!


• Health benefits plan - (a plan to make sure that you and your family are happy and healthy)


• Flexible work schedule - We understand that you and your family may have a busy schedule. We can accommodate that!


• Work from anywhere - The beach, a cabin in the woods, anywhere you have an internet connection and can be productive.


• Equipment to be productive - You’ll get a tech equipment allowance to make sure you are happy and efficient!


• Continuous learning opportunities and support for professional development. We want you to grow with us, and we will do anything we can to help!


• AI tools, your way - Our team uses agentic AI coding tools (including Claude Code) day to day, and we'll provide you a paid subscription. Use them as much or as little as you like: our workflows aren't set in stone, and there's room to experiment with how agentic engineering fits the way we build.

Position

As Viamo’s Senior Full Stack Engineer, you have a creative confidence for designing architectured solutions based on your many years of experience building across all layers of web applications. You are comfortable working with legacy codebases as well as greenfield projects.

Key Responsibilities

• Create scalable software that makes a difference to people’s lives:
  
  
  
  • Create solutions and follow-up - collaborate with team members to ensure the solution is driven through to completion.
  
  
  • Take a lead on planning - look at a list of requirements, provide realistic estimates and then work with Technical Project Managers to ensure fully realised tasks are created and ready to be worked on
  
  
  • Contribute to design - provide perspectives on some ways that solutions can be designed, from a developers perspective.
  
  
  • Be accountable to timelines - Make your work estimates visible, understand the impact it has on timelines and communicate with the team so that everyone is up to date on your progress.
  
  
  • Balance quick fixes and long-term quality solutions - build solutions quickly with an awareness of the larger product vision and be able to return and complete the work.
  
  
  • Provide examples - Use consistent coding patterns and implementation ideas to build a familiarity across the team
  
  
  
  

• Become a leader and inspire your colleagues:
  
  
  
  • Collaborate and contribute - Work across disciplines (engineering, QA, Infrastructure) and take responsibility by showing through example how to unleash others and move the team forward
  
  
  • Unblock others - Work with an awareness of the most important tasks to work on now, that will make a difference for the larger team and ask yourself - “What work can I do that will unblock others?”
  
  
  • Contribute to team processes and learning - so that the engineering team meets its goals of becoming smarter, more productive and healthier each sprint
  
  
  • Own what you ship - Take turns as the go-to engineer for production, digging into real-world issues across voice, SMS and AI, and help make our systems more observable, resilient and safe to roll out
  
  
  • Management Opportunities - If this is something that motivates you, you can manage and support your colleagues in their professional development
  
  
  
  

Location and employment

• Remote within Canada. You must be legally entitled to work in Canada.


• Permanent, full-time position. No equity.

Profile

Required

• Web App development experience - This is your thing! You love working across all layers of the application and can bring years of experience to our teams.


• API development experience - You know best-practices around making highly scalable, well-documented, and developer-friendly APIs.


• Ability to balance speed and quality - Based on the task at hand, you strike a balance between working efficiently and writing quality code.


• Build for scalability - You can come up with and implement scalable solutions utilizing all technologies and tools available to you like queues, caches, and smart design patterns.


• Proactive and continuous communication - Given a problem, you collaborate with others and keep everyone in the loop along the way.


• LLM and Language AI technology experience (optional but nice to have!) - Familiarity with using LLMs, speech-to-text and text-to-speech for real-time communication products like Interactive Voice Response (IVR).


• Telephony and audio processing experience (optional but nice to have!) - We work with telecom providers and VOIP technologies to deliver information to those who need it the most!


• Being open to thinking differently - Some designs need to be constrained within technical and/or architectural boundaries and other times designs need outside-the-box thinking! As a senior developer, you are able to understand what a given situation calls for and support designers on both ends of this spectrum. We work in niche areas that can be highly technically challenging and require creative solutions.
