Job summary

Ellume Solar Pvt. Ltd. seeks an experienced backend engineer to own features end to end, from problem definition through design, implementation, testing, rollout and production stability.

You will architect scalable backend services and APIs, model data stores for performance, and ensure smooth deployment and observability in production. Proactive prototyping and strong Go expertise are highly valued.

Qualifications

• 5+ years of backend experience.
• Deep fundamentals in system design, data modeling, concurrency, and API craft.
• Ability to break down unfamiliar problems and make architectural decisions.
• Proficiency in Go; hands-on production experience preferred.
• Working understanding of DevOps — CI/CD pipelines, containers, and cloud platforms (AWS, GCP, or Azure).

Responsibilities

• Lead features end to end from problem definition to production rollout.
• Design scalable, secure, and maintainable backend services and APIs.
• Turn ambiguous problems into clear technical plans and prototypes.
• Model and optimize relational and non-relational data stores for performance.
• Ensure features deploy smoothly, are observable, and recover gracefully in production.
• Mentor engineers, lead code reviews, and raise engineering bar.
• Collaborate with product, frontend, and operations to ship roadmap goals.

Job description

At Ellume, we are pioneering the future of clean power. We operate across three verticals—Renewable Energy, Independent Power Production (IPP), Engineering, Procurement & Construction (EPC), and Technology—committed to driving innovation across the renewable sector.

Responsibilities

• Lead features end to end — take ownership of a feature from problem definition through design, implementation, testing, rollout, and production stability.
• Design for scale and reliability — architect backend services and APIs that are scalable, secure, and maintainable, making deliberate trade-offs you can explain.
• Navigate the unknown — turn ambiguous, loosely specified problems into clear technical plans, and de-risk early through prototypes and spikes.
• Own data at the core — model, structure, and optimise relational and non-relational data stores for correctness and performance.
• Oversee delivery operations — work with the team to ensure your features deploy smoothly, are observable in production, and recover gracefully when things go wrong.
• Raise the engineering bar — write clean, well-tested code, lead design and code reviews, mentor other engineers, and level up the team's practices.
• Collaborate across functions — partner with product, frontend, and operations teams to turn roadmap goals into shipped outcomes.

Requirements

• Typically 5+ years of professional backend experience — we weigh scope of ownership over years served.
• Deep backend fundamentals: system design, data modeling, concurrency, and API craft, with the architectural understanding to shape how systems are designed, built, and operated.
• Comfort with ambiguity — able to break down an unfamiliar problem, make sound architectural decisions, and ask the right questions rather than wait for a complete spec.
• Willingness to become highly proficient in Go; hands-on production experience with Go is strongly preferred but candidates from other languages eager to make the jump are welcome.
• Working understanding of DevOps — CI/CD pipelines, containers, and cloud platforms (AWS, GCP, or Azure). Expertise is not required, but you should reason comfortably about how your code builds, ships, and runs.
• Nice to have: event-driven architectures and message brokers, multi-tenant SaaS platforms, IoT / telemetry / high-throughput data ingestion, the renewable energy or asset performance domain, and Clean or Hexagonal Architecture principles.
