****JOB SCAM ALERT**** We have been noticing a steady rise in job scams, where scammers are impersonating legitimate companies to defraud unsuspecting job seekers. To ensure your job search is safe, follow these quick safety tips and avoid potential scams: 1. Verify the Company's Legitimacy • Research the Employer: Look up the company online and verify their contact information on the official website. • Cross Check Email Domains: Legitimate companies use official email domains. Be wary of offers from generic email services or variations of the company’s actual domain (e.g., at LeadStack our actual email domain is leadstackinc.com; any variations like @leadstack-inc.com is a scam ). 2. Be Wary of Any Solicitation of Payments • Financial Details: Do not share bank details etc during the initial stages of the hiring process. • Upfront Payments: A legitimate employer will never ask you to pay for training, background checks, or any other job-related fees. 3.

Job description

LeadStack Inc. is an award-winning, one of the nation's fastest-growing, certified minority-owned (MBE) staffing services provider of contingent workforce. As a recognized industry leader in contingent workforce solutions and Certified as a Great Place to Work, we're proud to partner with some of the most admired Fortune 500 brands in the world.

Job Title: Senior Backend Engineer - Node.js/TypeScript, Distributed Systems
Duration: 12+ Months
Location: 100% Remote

Job Description:
The manager is looking for stronger alignment in a few key areas:
• Strong Node.js experience in addition to Java
• Meaningful, recent Azure experience
• Experience working with similar backend systems/platforms
• Resumes that clearly and accurately demonstrate the candidate's experience and work history

Additional Details
  • 12 month contract, with possibility to extend
  • Remote - Candidates can work from anywhere in the US. The current team is spread out.
  • This is a backfill, replacing an advanced/senior advanced team member
  • This role requires leadership skills and the ability to take on a lot of ownership
  • Though not required, prior tech lead experience is a plus. Someone who has architected solutions for a team, and can handle daily standups, scrum, etc.
What Makes Someone Successful
  • Thinks in systems, not just services.
  • Makes sound design decisions within an established architecture.
  • Writes clean, maintainable, and well-tested code.
  • Operates effectively when requirements are incomplete and knows when to ask versus when to decide.
  • Understands the importance of operational excellence and building software that is observable, reliable, and resilient.
  • Balances speed of delivery with long-term maintainability.
  • Communicates effectively across engineering, product, and business stakeholders.
  • This is a Node.js first environment, and Java heavy backgrounds without meaningful Node.js experience will not be sufficient.
Technologies You'll Work With
Node.js, TypeScript, Microsoft Azure, Azure Kubernetes Service (AKS), Azure Service Bus, Azure Functions, Cosmos DB, REST APIs, Docker, Kubernetes, Helm, GitHub Actions, OpenTelemetry, Dynatrace

Required Qualifications
  • 6+ years of professional software engineering experience building backend applications.
  • Strong recent production experience with Node.js and TypeScript, including asynchronous patterns and runtime performance characteristics.
  • Experience designing and building large-scale distributed systems in production environments.
  • Deep understanding of microservice architecture and event-driven application design.
  • Hands-on experience building and operating asynchronous, message-based systems. You should be able to speak concretely about idempotency, out-of-order delivery, retry and dead-letter handling, and consumer lag, from systems you have run rather than read about.
  • Experience developing and maintaining RESTful APIs.
  • Experience with NoSQL databases, including partitioning and consistency tradeoffs.
  • Strong, recent hands-on experience building and operating production applications on Microsoft Azure.
  • Experience with containerized applications using Docker and Kubernetes.
  • Strong understanding of CI/CD pipelines and modern DevOps practices.
  • Ability to diagnose problems from production telemetry: logs, traces, and metrics, rather than only from local reproduction.
  • Ability to work across team boundaries. This platform depends on systems owned by other teams, and you will need to go get answers rather than wait for them.
  • Excellent written and verbal communication skills.
Preferred Qualifications
  • Experience with Azure Kubernetes Service (AKS).
  • Experience with Azure Service Bus, Kafka, or similar messaging technologies, including topics, subscriptions, and filtering.
  • Experience with Cosmos DB or a comparable partitioned NoSQL store.
  • NestJS or a comparable structured Node framework.
  • Kubernetes autoscaling, Helm, and CI/CD pipeline work.
  • Experience with high-throughput systems where latency and cost per request are engineering constraints.
  • Experience implementing observability using OpenTelemetry and an APM platform such as Dynatrace, Datadog, or New Relic.
  • Experience working within large enterprise environments supporting mission-critical applications.
Key Responsibilities
  • Design, develop, and maintain scalable backend services using Node.js and TypeScript.
  • Build cloud-native applications on Microsoft Azure, leveraging platform services to create resilient, secure, and highly available solutions.
  • Contribute to the design and evolution of distributed systems supporting order fulfillment across thousands of stores.
  • Build event-driven services and asynchronous processing pipelines, including the correctness concerns that come with them.
  • Develop high-performance REST APIs that power associate-facing applications.
  • Diagnose performance and scaling behavior in production and lower environments: throughput ceilings, autoscaling, and resource sizing.
  • Extend observability, distributed tracing, and metrics so that system behavior is measurable rather than inferred.
  • Partner with Product, UX, Mobile, and Frontend teams to design APIs and services that deliver exceptional user experiences.
  • Contribute to technical design discussions and architecture reviews.
  • Identify opportunities to improve system reliability, scalability, observability, and operational efficiency.
  • Champion engineering practices including automated testing and CI/CD.
  • Support production readiness and the operational work that follows capacity, failure modes, and incident response.
  • Evaluate emerging technologies, including AI-assisted development tools, to improve engineering productivity and software quality.
