Senior Software Engineer

About the Role

As a Senior Software Engineer at Kixie, you will take end-to-end ownership of critical product subdomains - from architecture and design through implementation and production operations. You'll contribute to a modern, event-driven microservices platform built on Kubernetes and AWS, working across the full stack with a team that moves fast and ships high-quality software. This role requires strong technical judgment, the ability to lead initiatives across teams, and a mindset for building systems that are scalable, reliable, and observable by default.

What You'll Do

• Take full ownership of key product subdomains - including Telephony, CRM Integrations, Billing, and Observability - driving architecture decisions and long-term technical direction.
• Design, build, and maintain full-stack applications using React, Node.js, TypeScript, PostgreSQL, Kafka, OpenSearch, Kubernetes, and AWS Services. - Build and evolve deep integrations with third-party CRM platforms including Salesforce, HubSpot, Pipedrive, Zoho, GoHighLevel, etc.
• Contribute to our event-sourcing, microservices-based architecture - designing resilient, fault-tolerant services that operate at scale.
• Leverage AI tooling and LLM-based systems to enhance product features and build enterprise-grade capabilities that meet strict SLA requirements.
• Help build and enhance our observability platform which captures both system stability and user behavior that feeds into our business intelligence and ai platform.
• Manage and improve our CI/CD and AWS EKS infrastructure using Terraform for cloud provisioning and Ansible for on-premise Kubernetes cluster management.
• Champion best practices, test automation, and code quality standards across the engineering organization.

What We're Looking For

5+ years of professional software engineering experience, with demonstrated ownership of complex, production systems.
Strong full-stack proficiency with React, Node.js, and TypeScript; solid understanding of relational databases (PostgreSQL), NoSQL databases, and data platforms (warehouses, lakes, or lakehouses).
Experience with event-driven or event-sourcing architectures and distributed systems design.
Deep familiarity with AWS and Kubernetes (EKS); experience with infrastructure-as-code tools such as Terraform or AWS CDK/CloudFormation.
Hands-on experience with observability and monitoring tools such as Datadog, Grafana/Prometheus, or CloudWatch.
Experience with CI/CD pipelines using tools like GitHub Actions, Jenkins, or Travis CI.
Strong communication skills and the ability to lead technical initiatives, mentor peers, and influence architectural decisions across teams.
A critical, systems-level thinker who can evaluate trade-offs, propose multiple solutions, and align stakeholders around the right path forward.

Nice to Have

Experience with telephony providers such as Twilio, Plivo, or similar VoIP/CPaaS platforms.
Familiarity with CRM integration patterns and APIs (Salesforce, HubSpot, Pipedrive, Zoho, GoHighLevel).
Experience building or working with AI/ML systems, RAG pipelines, or LLM orchestration frameworks.
