ABOUT THE COMPANY

Alinea is building an AI-powered investing platform for the next generation. Post-Series A with 2.5M+ downloads, Alinea is scaling its platform and needs the technical foundation to match. The engineering team is lean, four engineers total, including a Head of Engineering, and this hire will be a meaningful addition to the core team, reporting directly to the Head of Engineering and working out of New York City.

ABOUT THE ROLE

As a Software Engineer, Reliability & Platform at Alinea, you'll own the technical foundation of the product — infrastructure, scalability, reliability, observability, and code quality across the full stack. This is a deeply technical, cross-stack role with meaningful architectural impact. You'll lead investigations into complex production issues, optimize systems across iOS, backend services, databases, and AWS infrastructure, and partner closely with product and engineering to drive platform-level improvements. This is a role for someone who has seen scale before, wants to get their hands dirty again, and is ready to own this function as a leader.

TECH STACK

• Swift + SwiftUI

• Node.js (Express) + TypeScript

• MongoDB

• AWS (Elastic Beanstalk, EC2, CloudWatch, CodeDeploy)

KEY RESPONSIBILITIES

• Lead deep investigations into complex production issues across iOS, backend services, and cloud infrastructure

• Perform root-cause analysis spanning API layers, async workflows, data models, third-party integrations, and infrastructure

• Improve backend service reliability, correctness, and performance in Node.js + TypeScript

• Optimize MongoDB queries, indexes, and data access patterns for performance at scale

• Strengthen AWS infrastructure stability across Elastic Beanstalk, EC2, deployments, and monitoring

• Improve observability using structured logging, metrics, and CloudWatch

• Reduce recurring bug classes by improving validation layers, error handling, and system boundaries

• Strengthen CI/CD and release processes to reduce production risk

• Build internal tools and scripts that improve debugging efficiency and engineering velocity

• Partner closely with product and engineering to drive platform-level improvements

REQUIREMENTS

Must-Have

• 3–7+ years of engineering experience — has seen scale and wants to own reliability and platform from the ground up

• Strong debugging skills in live production environments — you trace issues across multiple layers of the stack

• Deep understanding of APIs, async flows, and distributed system failure modes

• Experience building and improving services in Node.js + TypeScript

• Comfort navigating and contributing to Swift/SwiftUI codebases

• Strong understanding of MongoDB performance and data modeling

• Experience operating systems in AWS environments

• High ownership and strong execution in fast-moving environments

• Clear, structured communicator, low ego, collaborative, and direct

• Based in or willing to relocate to New York City

Nice-to-Have

• Fintech or payments experience

• Experience in improving production monitoring and alerting

• Experience hardening deployment pipelines

• Background from a strong engineering program, Georgia Tech, Carnegie Mellon, Stanford, or similar, preferred but not required if experience is strong
