Full Job Description

đź“‹ Description

  • • Lead the design, evolution, and production deployment of critical backend platforms that power electricity forecasting, pricing, optimization, and deal execution at scale.
  • • Build and maintain distributed systems using event-driven architectures, asynchronous workflows, and stateful workflows that ensure correctness and reliability in high-stakes energy transactions.
  • • Own and improve the operational foundations of core platform infrastructure, including observability, testing rigor, deployment safety, and incident reduction to minimize system failures.
  • • Design and implement scalable APIs, data models, and workflow orchestration systems that handle complex commercial processes with strict consistency and failure-recovery requirements.
  • • Collaborate directly with machine learning and data teams to productionize forecasting, optimization, and pricing models, ensuring safe, monitored integration into live transaction systems.
  • • Drive major technical initiatives from concept through production, balancing technical depth with business impact across engineering, product, commercial, and data teams.
  • • Mentor senior engineers and influence engineering standards organization-wide, raising the bar for architectural quality, code review practices, and system design documentation.
  • • Anticipate and preempt scaling challenges by proactively evolving platform architecture to support exponential growth in transaction volume and geographic expansion.
  • • Apply first-principles thinking to untangle ambiguous technical and organizational problems, delivering pragmatic solutions that align with customer outcomes and regulatory constraints.
  • • Work hands-on in production environments — writing code, reviewing designs, debugging system-level issues, and improving system resilience through direct contribution.
  • • Enhance developer productivity by improving internal tooling, deployment pipelines, and platform abstractions that reduce friction across engineering teams.
  • • Operate in a regulated domain with high stakes, ensuring systems meet the integrity, auditability, and operational clarity required for energy market infrastructure.
  • • Translate complex business requirements from commercial and customer teams into robust, scalable engineering solutions that directly impact revenue generation and market transparency.
  • • Contribute to technical roadmap planning by identifying architectural debt, proposing modernization strategies, and leading adoption of best practices in distributed systems engineering.
  • • Serve as a technical anchor across multiple engineering squads, unblocking delivery by aligning stakeholders and resolving cross-team dependencies in fast-moving environments.
  • • Evaluate and integrate emerging technologies and patterns that improve system throughput, resilience, and maintainability without compromising correctness or operational safety.
  • • Participate in on-call rotations and incident reviews to ensure rapid resolution of production issues and continuous learning from system failures.
  • • Champion operational excellence by implementing robust monitoring, alerting, and telemetry across the platform to enable proactive system health management.
  • • Support international expansion by designing systems with multi-region, multi-currency, and regulatory compliance considerations built-in from the ground up.
