Senior Platform Backend Engineer - Battery Storage

About the Role 

Plus Power recruits outstanding energy industry professionals who are driven to develop, build and operate assets safely and reliably to decarbonize the power markets while growing their careers. Our team looks for data-driven and fact-based mindsets, engaging and collaborative behaviors, and personal growth-focused professionals.   

We are seeking a Senior Platform Engineer to join our technology team, with a focus on backend systems, cloud-native platforms, and data infrastructure. This role is ideal for an engineer who comes from a data platform, backend, or analytics engineering background and has developed deep expertise operating those systems in AWS at scale. It is especially well suited for engineers who have built or operated data platforms and are looking for deeper ownership of the cloud and backend systems that power them. 

You will work at the boundary between data platforms, application engineering, and cloud infrastructure, helping Plus Power build reliable, scalable systems that support asset operations, analytics, and power market participation. This is a hands-on role with meaningful technical ownership: you will write production code, shape system architecture, and ensure the systems you build are observable, resilient, and operable in real-world conditions. You will focus on bringing transparency, efficiency, and consistency to our cloud systems, ensuring secure and flexible deployment patterns, and advocating for best practices, all while contributing directly to business-critical solutions. 

In this role, your impact goes beyond ticket-based support or reactive operations. You will lead and own solutions end-to-end, from design and implementation through deployment, monitoring, and ongoing evolution. You will be working across disciplines to continuously improve the platforms and systems our teams rely on.

• Work closely with data engineers and analysts to ensure systems meet requirements for data correctness, availability, and performance. 
• Set and evolve best practices for cloud-based data management through platform design, automation, and standards. 

Operational Excellence & Reliability 

• Build and evolve CI/CD pipelines that test, validate, and deploy both application and infrastructure code. 
• Establish and maintain observability standards using metrics, logs, and alerts. 
• Participate in on-call rotations and lead root cause analysis and long-term system improvements following incidents. 

Skills & Qualifications 

• 5+ years of professional experience across platform engineering, backend engineering, data engineering, CloudOps, or SRE roles. 
• Strong backend development experience, including building and operating production services or internal platforms. 
• Prior experience on data platform, analytics, or ML infrastructure teams preferred. 
• Significant hands-on experience with AWS, including services such as VPC, IAM, EKS/ECS, RDS, S3, and related managed services. 
• Familiarity with event-driven architectures, messaging systems, or streaming data patterns preferred. 
• Experience with Infrastructure as Code (Terraform and/or CloudFormation). 
• Experience operating containerized workloads using Docker and Kubernetes in production environments. 
• Solid understanding of CI/CD, Git-based workflows, and automated testing. 
• Strong operational mindset, including comfort owning production systems and participating in on-call rotations. 
• Experience building or evolving internal developer platforms or shared infrastructure services preferred. 
• Experience working with relational databases and data-intensive systems. 
• Excellent written and verbal communication skills, with the ability to present complex technical information to diverse audiences. 
• Demonstrated ability to work collaboratively and effectively in a cross-functional environment with both technical and non-technical team members who are geographically dispersed 
• Proven ability to stay connected and maintain communication across distributed teams in hybrid or remote settings.
