You must be based in LATAM for this fully remote role (Our client is located in Canada). Excellent English skills (written & spoken) are required.

Our client is an AgTech SaaS startup that provides a digital platform that helps farmers manage equipment maintenance, service history, costs, and more. Using QR codes and a mobile app, farmers and their teams can easily log repairs, track service history, attach invoices, manage maintenance schedules, and monitor costs for each piece of equipment.

The product is already live and used in production. The company is now focused on hardening the platform, scaling the system, and future-proofing the architecture.

This is a high-ownership role in a small, experienced team where engineering decisions matter.

This role is focused on improving and scaling an existing production system.

We are looking for a Senior Backend Software Engineer to help strengthen and scale an existing SaaS platform. This role is ideal for an engineer who enjoys working on databases, system performance, reliability, and backend architecture rather than building UI features.

You will work closely with the team to identify bottlenecks, improve scalability, and ensure the platform is ready for long-term growth.

This is an opportunistic hire for an A++ engineer. There is a high bar.

Responsibilities:

Own backend initiatives end-to-end, from design to deployment
Design, optimize, and maintain PostgreSQL database schemas, queries, and data models
Improve backend performance, scalability, and reliability across the system
Identify and resolve architectural bottlenecks in existing services
Build and maintain backend services and APIs using Node.js / TypeScript
Strengthen system robustness, monitoring, and long-term maintainability
Collaborate with frontend engineers as needed

This role is NOT for candidates whose experience is primarily feature delivery rather than system scaling, mid-level engineers, or frontend-focused developers.

Must-haves (non-negotiable)

6+ years of professional backend engineering experience in production environments
Deep, hands-on experience with Node.js using JavaScript and TypeScript (not exposure, not side projects)
6+ years working with relational databases, including PostgreSQL, with ownership over:
- Schema design
- Query optimization
- Data modeling decisions
Proven experience scaling and hardening live SaaS systems used by real customers
Demonstrated ownership of backend architecture decisions in startup or scale-up environments
Strong understanding of system performance, reliability, and long-term maintainability
Comfortable working in existing codebases and improving what is already built (not just greenfield work)
Ability to operate independently, identify bottlenecks, and propose solutions without detailed direction

Nice to have (not required)

Experience with Supabase or similar backend infrastructure platforms
Familiarity with frontend frameworks (Vue.js / Nuxt.js) for collaboration context only

Benefits:

Fully remote
Holidays + PTOs
Growth opportunities
