About the team - Tackle

Tackle, a business unit of AppDirect, is the leading solution built to help software companies generate revenue through data-driven Cloud go-to-market (Cloud GTM). Our platform and team help customers identify the right buyers, grow cloud co-sell relationships, and transact efficiently at scale through AWS, Google Cloud, and Microsoft.

Tackle serves more than 500 software companies-including CrowdStrike, HashiCorp, New Relic, and Snyk-from high-growth startups to the largest software companies in the world.

About You

You'll join a small, high-ownership team building the intelligence layer of Tackle's platform - turning machine learning models into real product experiences that customers use every day. Your day-to-day work spans the full stack: TypeScript on both the backend (Node.js) and frontend (React), running on AWS serverless infrastructure including Lambda, API Gateway, and DynamoDB. Because the team is small, you'll own meaningful portions of the product end to end, collaborating directly with a product manager and a data scientist to ship features that are highly visible across Tackle's customer base. You bring a growth mindset to your work - you're comfortable asking questions, learning new services quickly, and closing gaps through curiosity rather than waiting for perfect prior experience. You communicate clearly in a distributed team setting and take pride in writing code that is testable, maintainable, and ready for production.

What you'll do and how you'll have an impact

• Build and maintain full-stack features on Tackle's propensity-to-buy product, exposing machine learning model outputs directly to customers through a React frontend and TypeScript/Node.js backend.
• Design and implement serverless backend services using AWS-native tools such as Lambda, API Gateway, and DynamoDB.
• Contribute to data pipeline work that moves and associates model outputs with the right users and accounts.
• Take end-to-end ownership of features - from design through deployment - on a team where your contributions are immediately visible in production.
• Collaborate daily with a product manager and data scientist to shape how AI-driven insights are surfaced in the product interface.
• Participate in code reviews to uphold code quality standards and share knowledge across a small engineering team.

What we're looking for

• 2+ years of professional experience building full-stack web applications, with working knowledge of both frontend and backend layers.
• Professional experience with React and TypeScript (or strong proficiency in JavaScript/TypeScript with demonstrated readiness to work in a TypeScript-only codebase).
• Hands-on experience deploying applications on AWS, particularly with serverless services such as Lambda, API Gateway, or DynamoDB.
• Familiarity with data pipelines or moving/transforming data between systems (nice to have, but valuable given how the team operates).
• Exposure to machine learning model integration or building AI-powered product features is an asset, not a requirement.
• A strong sense of ownership, because on a team this small you will hold significant responsibility for product areas and need to drive work forward with limited direction.
• Intellectual curiosity that leads you to understand how your code fits into the broader system - this matters because you'll work across the stack and alongside non-engineering roles where asking the right questions shapes outcomes.
