About Upstack Data
Upstack Data is a Miami-based SaaS building marketing automation for Shopify merchants. Our flagship product, Signal, replaces broken browser-based pixels with reliable first-party server-side events to Meta, TikTok, and other ad platforms. We're a lean, AI-first team running offshore-first - most of our engineering, GTM, and operations roles are filled with PH talent.

About This Role
We are seeking a talented and product-minded Senior Software Engineer (Backend) to join Upstack Data. In this role, you will own our backend infrastructure — building and maintaining the serverless APIs, data pipelines, and integrations that power our customer identity resolution platform. You will work directly with our CEO to translate business requirements into reliable, scalable backend systems, making independent architectural decisions throughout the product development lifecycle from initial concept to deployment and optimization.

A distinguishing aspect of this role is your ability to design robust, event-driven systems without extensive hand-holding. You will influence product and technology decisions, establish backend patterns and best practices, and build systems for complex features including data ingestion pipelines, third-party integrations (Shopify, Meta, Google Ads, Klaviyo), webhook processing, and high-throughput analytics queries. This is an excellent opportunity for someone passionate about building performant B2B SaaS infrastructure with a strong understanding of what makes platforms like Segment, Stripe, and Mixpanel reliable and scalable.

What You'll Do
Design, develop, and maintain scalable backend services and APIs using Node.js, TypeScript, and AWS Lambda
Make independent architectural decisions on data models, API design, service boundaries, and system reliability that create robust, maintainable systems
Collaborate with the CEO on product requirements, providing technical perspective on feasibility and proposing alternative approaches that balance user value with engineering effort
Establish and maintain backend patterns, coding standards, and best practices to ensure consistency and reliability across the platform
Build and optimize data pipelines for ingesting, processing, and analyzing customer behavior data at scale
Integrate backend services with third-party platforms including e-commerce systems, advertising APIs, email marketing tools, and payment processors
Participate in code reviews and contribute to establishing backend engineering standards and best practices
Optimize application performance focusing on response times, database query efficiency, and cost optimization
Write comprehensive tests using modern testing frameworks to ensure code quality and reliability
Monitor and analyze backend performance metrics, addressing issues proactively
Implement proper error handling, logging, and alerting to maintain system health
Support deployment, monitoring, and troubleshooting of applications in production environments
Stay current with AWS serverless ecosystem trends and emerging backend technologies to continuously improve our platform

Requirements
3+ years of hands-on experience developing production Node.js applications with TypeScript
Expert proficiency in serverless architecture patterns using AWS Lambda, API Gateway, and related services
Strong experience with both SQL (PostgreSQL) and NoSQL (DynamoDB) databases, including data modeling and query optimization
Solid understanding of event-driven architectures, message queues (SQS, SNS, EventBridge), and asynchronous processing patterns
Experience building and consuming RESTful APIs, with knowledge of authentication patterns (OAuth, JWT, API keys)
Strong experience integrating with third-party platforms and APIs (payment processors, e-commerce platforms, advertising APIs, marketing tools)
Familiarity with infrastructure-as-code tools (Serverless Framework, AWS CDK, or Terraform)
Experience with Git workflows, CI/CD pipelines, and modern deployment practices
Knowledge of backend testing frameworks and best practices for code quality
Understanding of monitoring, logging, and observability practices (CloudWatch, DataDog, or similar)
Excellent communication skills and autonomous problem-solving abilities
Available for 4–5 hours overlap with US Eastern timezone
Strong English verbal and written communication

Nice to Have
Experience with e-commerce platforms (Shopify, WooCommerce, BigCommerce)
Familiarity with advertising platform APIs (Meta Marketing API, Google Ads API)
Experience with data warehousing or analytics pipelines
Background in identity resolution, customer data platforms, or marketing attribution
