Job description

Senior Software Engineer II - Platform & Integrations (Backend)

Overview

We are looking for a Senior Software Engineer II to design, build, and operate large-scale distributed systems and services for an enterprise SaaS organization. In this role, you will help shape resilient, AI-native software delivery practices while building high-availability services that support modern cloud platforms and customer-facing product experiences.

Who you are

• Extensive experience designing and operating enterprise-grade SaaS systems, distributed services, and cloud operational infrastructure for scalability, reliability, security, and high availability.
• 7+ years of experience with C# and .NET, or another major object-oriented programming language, and web services.
• 3+ years of experience with PostgreSQL or major RDBMS, including performance tuning, maintenance, schema design, and operational best practices.
• Proficiency with Test-Driven Development (TDD), Domain-Driven Design (DDD), API testing, and modern engineering quality practices.
• Experience with event-driven architectures using technologies such as Kafka or RabbitMQ, and in-memory data stores such as Redis.
• Hands‑on experience with container technologies and cloud-native platforms such as Docker, Kubernetes, Istio, etcd, and service mesh architectures.
• Experience with AWS, GCP, or Azure, including deploying and operating containerized workloads on Kubernetes in production.
• Familiarity with CI/CD pipelines, Infrastructure as Code, and tools such as Terraform or Pulumi.
• Experience mentoring engineers, leading design reviews, and influencing technical direction across teams.
• Proven ability to collaborate effectively with product, design, engineering, and globally distributed teams.
• Experience working in a fast-paced, dynamic environment, preferably in a SaaS or technology-driven company.

Preferred qualifications

• Experience with AI-native development tools and platforms such as Claude, GitHub Copilot, Agentforce, or similar tools.
• Hands‑on experience with LLMs, RAG, model integration patterns, AI-assisted workflows, or intelligent product features.
• Experience with observability, analytics, automation, or data platforms such as New Relic, Snowflake, Ansible, or Python.
• Experience with major CRM ecosystems such as Salesforce or Microsoft Dynamics.
• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.

Why this role matters

This role is an opportunity to help build the next generation of enterprise SaaS systems in an AI-native engineering environment. You will have meaningful impact on platform architecture, developer productivity, service reliability, and the intelligent capabilities that power customer-facing products while growing with a collaborative team that values ownership, innovation, and technical excellence.

What you’ll be doing

• Design, develop, and operate enterprise-grade distributed systems and services that are scalable, reliable, secure, and highly available.
• Own end-to-end technical design for key services and subsystems, evaluate architectural trade-offs, and drive implementation decisions across backend services, cloud infrastructure, and data platforms.
• Build and maintain production services using C#/.NET or other major object-oriented programming languages, web services, and modern API patterns.
• Apply AI-native development practices — including LLM-assisted development, retrieval-augmented generation (RAG), and agentic workflows — to accelerate delivery and build intelligent product capabilities.
• Collaborate closely with product management, design, and distributed engineering teams to translate business needs into technical solutions from concept through launch.
• Improve engineering quality through Test-Driven Development (TDD), Domain-Driven Design (DDD), automated testing, observability, and operational excellence.
• Identify and drive improvements to system reliability, performance, scalability, and developer experience across the platform.
• Participate in on-call support rotations and incident response to ensure service reliability, availability, and timely resolution of production issues.
• Mentor engineers, participate in design and code reviews, and help raise the technical bar across globally distributed teams.
