Software EngineerSoftware Engineering

In this remote role, you will design and build high-performance backend systems that support critical platform infrastructure and deliver reliable services at scale. You will lead the architecture and development of low-latency REST APIs, optimize database performance, and strengthen the resilience and security of distributed services. Working primarily with Python, Flask, and SQLAlchemy, you will help establish engineering standards and improve the quality of backend solutions. You will collaborate with cross-functional engineering teams to define API contracts, integration patterns, and scalable architectural approaches. The position combines hands-on technical delivery with architectural leadership, design reviews, and mentorship for engineers at different career stages. You will also explore modern AI tooling and agentic workflows while contributing to secure, observable, and fault-tolerant systems in a cloud-based environment.

Architect, design, develop, and evolve scalable, high-throughput, low-latency REST APIs and backend service layers using Python and Flask.
Design robust database schemas and optimize queries using SQLAlchemy and relational database technologies to maintain performance, consistency, and availability.
Lead technical design reviews, establish backend engineering standards, and promote best practices across development teams.
Mentor junior and mid-level engineers, providing technical guidance and helping strengthen engineering quality and problem-solving capabilities.
Implement authentication, rate limiting, and observability capabilities across distributed backend services to improve security, monitoring, and operational reliability.
Design fault-tolerant services that handle failures gracefully under heavy workloads, using techniques such as circuit breakers, defensive validation, and resilient error handling.
Define and maintain API contracts, versioning strategies, architecture patterns, and integration workflows in collaboration with cross-functional teams.
Apply best practices for RESTful architecture, HTTP protocols, and API security to ensure consistent and reliable service interactions.
Contribute throughout the full product lifecycle, from architectural planning and implementation to testing, deployment, monitoring, and continuous improvement.
Support engineering delivery through effective Git workflows, CI/CD pipelines, cloud platforms, and containerization technologies.
Incorporate automated testing, distributed systems principles, event-driven architectures, and observability tools into backend development practices.
Explore and apply relevant AI tooling, agentic workflows, transformer architectures, and background processing systems to enhance platform capabilities.
