Senior Python Software Engineer - Backend & Architecture

About the Role

We are looking for a Senior Python Software Engineer - Backend & Architecture to join our team at Exandia. This remote position offers an exciting opportunity to lead the design and implementation of core backend services and cloud infrastructure. You will play a crucial role in driving large-scale technical initiatives from problem definition to architecture to delivery.

What You'll Do

• Design, implement, and maintain backend services, APIs, and microservices primarily using Python (FastAPI).
• Architect scalable, resilient systems capable of processing real-time operational data from field devices.
• Lead end-to-end design for complex, revenue-critical features, ensuring technical clarity, documented requirements, and well-defined success metrics.
• Evaluate system bottlenecks and propose architectural improvements in performance, reliability, and maintainability.
• Build and optimize cloud-native data ingestion pipelines using Azure & AWS services such as IoT Core, Kinesis, SQS, Lambda, EC2, EKS, RDS/Aurora PostgreSQL, and S3.
• Collaborate with DevOps to design infrastructure that meets operational and security standards (containerization, Kubernetes, autoscaling, CI/CD, observability).
• Implement distributed processing and efficient handling of large real-time telemetry streams.
• Work closely with product managers and stakeholders to clarify requirements, explore design options, and break down large initiatives into executable engineering tasks.
• Coordinate with frontend teams to align API contracts, data models, and release timelines.
• Provide architectural guidance, code reviews, and mentorship to other engineers.
• Write clean, maintainable, well-tested code following industry best practices.
• Maintain service reliability through robust logging, monitoring, alerting, and automated testing strategies.
• Contribute to improving internal engineering documentation, standards, and design processes.

Requirements

• 4-6+ years of professional software engineering experience, with a strong emphasis on backend systems.
• Excellent/Expert-level Python experience, ideally with FastAPI in production environments.
• Strong understanding of distributed systems, microservice architecture, and API design.
• Hands-on expertise with AWS cloud services (IoT Core, Lambda, Kinesis, SQS, EC2, EKS, S3, RDS/Aurora).
• Experience building or maintaining real-time data processing pipelines or IoT ingestion systems.
• Solid understanding of Docker, Kubernetes, container orchestration, and cloud-native patterns.
• Infrastructure as code (IaC) experience (e.g. Terraform).
• Strong proficiency with SQL and experience working with relational databases (preferably PostgreSQL).
• Ability to independently gather requirements, write technical specs, and drive projects to completion with minimal oversight.
• Strong communication skills and the ability to work cross-functionally with product, frontend, and DevOps teams.

Nice to Have

• Experience with TypeScript and modern FE/backend integration patterns.
• Familiarity with message-driven architectures (Kafka, MQTT, etc.).
• Exposure to machine learning pipelines or algorithmic/analytics workloads.
• Understanding of best practices for security, compliance, networking, and IAM within AWS.
• Prior experience in oil & gas, energy tech, or real-time industrial data processing.

What We Offer

• Competitive salary ranging from $120,000 to $150,000 annually.
• Fully remote work environment, allowing for flexibility in your schedule.
• Opportunities for professional development and growth within the company.
• Collaborative and innovative team culture.
• Access to cutting-edge technologies and tools.
• Health and wellness benefits.
• Support for continuous learning and training.
• Participation in exciting projects across various industries.
