Fullstack Engineer

Proto is hiring a full stack engineer to build and maintain the software and infrastructure behind our AI agent platform – the products that put AI agents in the hands of governments, regulators and businesses across emerging markets.

You will own features from first idea to production, learn our SaaS products inside out and use AI tools every day to move faster and ship better. You will work in a lean, remote-first team where good ideas become live code in days, not quarters.

Location: Pakistan

You will turn complex AI capability into products that people actually use.

• Build and develop the applications, servers, services and databases that form the foundation of our platform

• Develop a complete understanding of our SaaS products and take part in end-to-end product development

• Use AI coding assistants and agentic tools daily to design, write, test, debug and review code – and share what works with the team

• Proactively improve the architecture and pay down technical debt

• Keep the codebase healthy – maintainable, scalable, secure and bug-free – and hold quality to the highest standard, including for code generated by AI

• Collaborate with our product, QA and client support teams

You are a builder who is equally at home on the server and in the browser.

• 3+ years' professional experience with Python and TypeScript development

• A proven habit of using AI tools – coding assistants, agents, automated testing and review – to raise your speed and output, while checking everything they produce

• Good judgement in choosing the right tool for each task, rather than building everything in-house

• Strong Python 3 and FastAPI skills, including multi-threading, asyncio and performance optimisation

• Strong relational database skills: writing SQL queries or using an ORM

• Experience with Docker and Docker Compose

• Experience with AWS and managing deployments

• Experience with micro-services and Kubernetes

• Experience with Celery and RabbitMQ

• Sound knowledge of React and TypeScript

• Understanding of modern web principles, and responsive web design

• Ability to troubleshoot performance issues using developer tools

None of these is essential, but each will help you hit the ground running.

• Background in natural language processing or computational linguistics

• Previous experience at a SaaS or AI company

• Fluency in multiple languages

• Experience integrating LLMs or AI agents (APIs, prompt design, retrieval)

• Familiarity with messaging channels such as WhatsApp, SMS, voice or web chat

Proto is a Canadian-registered AI communication platform company deploying AI agents for governments, regulators and private sector organisations across emerging markets. The work is real, the impact is public and the team is small enough that you will shape what we build.

• Real-world impact: your code serves citizens, institutions and businesses in markets where good technology changes daily life

• Ownership: a lean team means broad scope, fast decisions and visible results

• Global reach: work with clients and colleagues across multiple countries and regions

• Growth: learn from the frontier of applied AI, with room to grow into technical leadership

• Remote-first: we have worked remotely since the start, with a tested process for team collaboration that maximises productivity
