As a Senior Backend Engineer, you will be crucial in designing and building core platform services that demand non-negotiable correctness and unforgiving scale. This role involves architecting systems from first principles, making long-term architectural decisions, and challenging requirements to ensure robust and scalable solutions for B2B companies. You will be instrumental in shaping the platform for years and driving engineering quality across the team.

Key Responsibilities

• Develop and maintain core platform services that manage complex business logic efficiently and reliably at scale.
• Design and oversee integrations with external enterprise systems, effectively handling their unique behaviors, rate limits, and failure scenarios.
• Create APIs that are well-received and easy to integrate by enterprise engineering teams.
• Manage end-to-end production debugging, identifying and resolving issues across services by analyzing logs, traces, and metrics.
• Collaborate closely with product, implementation, and customer success teams, serving as the engineering expert with in-depth system knowledge.
• Incorporate security and compliance considerations into system design and development as a standard practice.
• Lead architectural design and code reviews, establishing and upholding engineering standards.
• Mentor fellow engineers to elevate team performance while maintaining productivity.

Qualifications

• Over 5 years of professional experience in software development, focusing on building scalable production systems.
• Bachelor's degree in Computer Science or equivalent hands-on experience, with solid understanding of data structures, algorithms, operating systems, and networking.
• Proven capability to clearly communicate complex technical challenges, their solutions, and the impact of those solutions.
• Expertise in at least one backend programming language, demonstrating strong engineering judgment.
• Excellent system design skills, including the ability to evaluate trade-offs, anticipate failure modes, and ensure long-term maintainability under pressure.
• Practical experience using observability tools—such as logs, traces, and metrics—for troubleshooting complex problems in distributed systems.
• Knowledge of security and compliance frameworks (e.g., SOC 2, DPDPA) and their implementation implications in engineering.
• Hands-on experience working with event-driven architectures like Kafka, NATS, or RabbitMQ.
• Experience deploying and managing services at scale on cloud platforms, preferably AWS.
• Background in B2B SaaS or enterprise software, including multi-tenant architectures, external system integrations, and enterprise workflow management.
• Strong dedication to maintaining a comprehensive testing strategy, covering unit, integration, and end-to-end tests.
• Familiarity with containerization technologies such as Docker and Kubernetes, as well as CI/CD tools like GitHub Actions.
• Experience working with financial systems, billing platforms, or fintech applications.
• Understanding of SaaS business models and pertinent regulatory compliance standards.
• Demonstrated success in designing and integrating APIs.
