Remote Freelance Full Stack Developer Jobs in Orlando, FL

Worth AI, a leader in the computer software industry, is looking for a Senior Engineer to join our Platform team with a singular mission: to make our engineering organization faster, more reliable, and more joyful. In this role, you won't just be building features for end-users; you will be building the "Product for the Engineers." You will act as a force multiplier by identifying friction in the development lifecycle, architecting shared patterns, and unblocking technical debt that slows the team down. You are part architect, part investigator, and part educator.

• Conduct regular interviews with engineering teams to find pain points in their daily workflows and prioritize the creation of tools or architectural changes to eliminate them.
• Design and implement reusable patterns using Nest.js, React.js, and TypeScript that enable other engineers to ship high-quality, performant services and interfaces by default.
• Take ownership of systemic performance issues, such as optimizing slow PostgreSQL queries or refining Kafka producer/consumer patterns to ensure reliable message delivery.
• Own and evolve our Kubernetes and ArgoCD configurations to ensure seamless, automated, and safe deployments across the organization.
• Lead nebulous, cross-team technical challenges such as re-architecting shared libraries or evolving our service-to-service communication and drive them to a concrete resolution.
• Identify "sticky" or overly complex codebases and lead the effort to refactor them into maintainable, testable, and modern modules.
• Actively mentor and coach engineers across the organization, helping them level up their technical skills and understanding of our core architecture.
• Research, prototype, and roll out new internal tools, libraries, or frameworks that improve CI/CD, local development, or system observability.
• Introduce new frameworks or architectural shifts to the team and provide the documentation, workshops, and 1:1 support needed for successful adoption.
• Lead by example in code reviews, coaching others on maintainable design, testing strategies, and system-level risk mitigation.
• Communicate complex technical trade-offs effectively across functions, using empathy and self-awareness to handle conflict and align differing perspectives.

Technology Stack

• Languages & Runtimes: Node.js, TypeScript
• Frameworks: Nest.js, React.js
• Data & Messaging: PostgreSQL, Kafka, Redis, Redshift
• Infrastructure & Orchestration: Kubernetes, ArgoCD
• Monitoring: DataDog

Requirements

• 8+ years of experience in software engineering with a proven track record of leading teams and providing technical direction.
• Deep passion for mentorship with a history of developing the technical careers of associate and intermediate engineers.
• Prior experience specifically within Platform, Infrastructure, or Developer Experience (DevEx) teams.
• Deep professional expertise in the Node.js/TypeScript ecosystem, including experience scaling Nest.js backends and React.js frontends.
• Hands-on experience managing containerized workloads using Kubernetes and ArgoCD.
• Strong proficiency in PostgreSQL (query optimization and schema design) and Kafka (event-driven architecture).
• Proven ability to "unroll" complex legacy code and replace it with scalable, maintainable architecture.
• Experience navigating high-ambiguity environments and translating vague technical frustrations into prioritized roadmaps.
• Demonstrated ability to build psychological safety and trust within a team while raising the engineering quality bar.

• DORA Metrics Improvement: Drive measurable improvements in Deployment Frequency, Lead Time for Changes, Change Failure Rate, and Mean Time to Recovery (MTTR).
• System Latency: Successfully optimize core services to meet strict P90 and P99 latency targets, specifically targeting slow endpoints and database bottlenecks.
• Developer Velocity: Engineers ship code faster and more confidently due to the shared components, patterns, and tools you've built.
• Knowledge Distribution: The broader engineering team demonstrates increased proficiency in our core stack (Nest.js, React, Kafka) through your mentorship.

• Proven expertise with AWS services including MSK, RDS, EKS, S3, and Lambda.
• Strong background in Redshift, encompassing schema design, ETL pipeline management, and query optimization.
• Practical experience using Infrastructure-as-Code (IaC) tools like Terraform for managing large-scale cloud environments.
• Hands-on experience with Redis and implementing distributed system caching strategies to resolve bottlenecks in high-throughput applications.
• Proficient in Python, including libraries like Celery and SQLAlchemy.
• Familiarity with serverless computing approaches.
