Job description

Intro

Come join our Engineering team! High velocity, high intensity, high trust, high bar, high impact, and a will to win. If that resonates deeply with you, this could be your next career move. We're seeking someone who leads with humility, pursues audacious goals, and is motivated by meaningful impact on people and the world.

Our Mission

At FutureFit AI, our core mission is to help more people get to better jobs faster and cheaper, with a specific focus on those facing barriers to opportunity. Our work helps resolve the growing issue of economic inequality, ensuring that no one is left behind in the future of work. Our AI-powered platform brings efficiency and insight to workforce development, replacing outdated systems and unlocking human potential at scale.

Important Note

Important note: Data shows that men typically apply when meeting 3/10 requirements, while women often wait until it's 10/10. We encourage you to apply if you see a strong (not necessarily perfect) fit.

Our Company

Team: 30 to 50 people across the US and Canada, with main hubs in New York and Toronto

Funding: Built from 0 to 1 with no external capital (a rare feat for tech startups), then raised one round of funding led by JP Morgan, which fueled significant growth

The Opportunity

We're seeking a Senior Backend Engineer (Integrations & Platform) to build the backbone our platform runs on. You'll design scalable backend systems that power complex data integrations with government and enterprise partners, remove manual operational work, and help the team move faster with less friction.

This is a build role and an operate role: when a sync fails or a record looks wrong, you can trace it back to the cause and fix it.

Your Role

Our integration footprint has grown quickly, and the most demanding piece is a bidirectional data sync with an external partner that requires sophisticated error handling, async workflows, and operational automation. You'll start there, then turn what you build into the patterns and infrastructure we use for integration reliability across the platform. This is hands-on, high-impact work where you'll see results quickly: fewer production issues, faster support resolution, and systems that scale with confidence.

What You'll Own

• Complex data integrations: Design, build, and maintain deep, bidirectional data integrations with government and enterprise partners, including partners with limited documentation.


• Asynchronous workflows: Build reliable async processing using queues, retries, idempotency, and eventual consistency patterns, handling duplicates, missing dependencies, and validation failures defensively.


• Operational automation: Eliminate categories of manual support work through backend services, Lambda functions, and internal tools that let non-technical teammates diagnose and resolve issues themselves.


• Observability: Implement structured logging, metrics, tracing, and alerting so issues surface before support tickets do.


• Production reliability: Stay close enough to running systems to debug them, including code you did not write.


• Reusable patterns: Establish integration standards the rest of the team can build on.


• Partner collaboration: Work with external vendors on API changes and coordinated deployments.

Your 30/60/90 Day Plan

1. First 30 Days: Learn and Integrate
   - Build relationships with the engineering, customer success, and support teams who interact with our integration systems daily
   - Deep dive into our most complex integration: the bidirectional sync architecture between our platform and external partners (APIs, data models, async workflows, error patterns)
   - Get hands‑on with our debugging tools: MongoDB queries for async job tracking, CloudWatch Logs Insights for distributed tracing, SQL queries for data validation
   - Ship your first small fixes or improvements: resolve straightforward integration bugs or improve observability in one workflow


2. Days 31 to 60: Own and Execute
   - Take ownership of your first major automation initiative: eliminate a category of manual support work
   - Build and deploy backend services and Lambda functions that reduce manual intervention in the integration pipeline
   - Implement comprehensive observability (structured logging, metrics, and alerting) so issues surface before support tickets
   - Work with the support team to validate that your automation eliminates manual work, and identify the next highest‑impact opportunity
   - Document runbooks and create internal tools that empower non‑technical team members to diagnose and resolve common issues independently
   - Collaborate with external partners on any API changes or coordinated deployments your automation needs
   - Begin identifying patterns and infrastructure that can be reused across other integrations or platform systems


3. Days 61 to 90: Lead and Amplify
   - Measure and communicate the impact of your automation: reduc
