The Job

As a Senior Software Engineer on our Data Management team, you will own the APIs and services that ingest, validate, and transform the IoT data powering our business. We are looking for a strong backend engineer with deep roots in object-oriented design who is ready to apply those skills to modern data challenges. You'll collaborate with a hybrid team of data engineers, software engineers, and data scientists to ensure our data remains a strategic asset, while exploring AI-driven enhancements and leveraging large-scale distributed processing and streaming technologies. If you are a backend engineer who is data-curious-or already data-fluent-this role offers the autonomy to build systems that directly power a sustainable future.

What You'll Do

• At Omnidian we believe in trust and autonomy. How you create an impact is ultimately up to you. Here is an outline of some of the things you'll be doing:

Core Engineering, Data Ingestion & API Systems

• Design and maintain robust backend services using object-oriented principles to manage asset configurations, onboarding workflows, and time-series metadata
• Build and optimize internal APIs that securely and efficiently serve data to other internal teams and stakeholders
• Own and maintain existing API-based ingestion services while collaborating on the evolution of our data platform toward distributed processing and streaming models
• Work alongside Data Science and Data Engineering to integrate AI-driven insights and automated logic into our core services to improve data accuracy and operational efficiency

User & Business Understanding

• Partner with business stakeholders to translate solar energy concepts (like inverter telemetry and battery states) into clean, scalable models
• Act as a consultant for internal data consumers to ensure our APIs and metadata services meet the evolving needs of the organization
• Use data and stakeholder feedback to prioritize service reliability and scalability where it impacts the business most

Grow With The Team

• Learn and contribute to our large-scale distributed processing stack, moving beyond traditional backend services and build knowledge with Spark, Python and Lakehouse architectures
• Explore and champion the use of AI-driven tools and workflows to automate data validation and enhance our predictive capabilities
• Help drive the adoption of Databricks and other cloud-native data platforms as we scale our streaming and ETL capabilities
• Share your expertise in object-oriented design with the broader data team while learning modern data engineering patterns in return

Technical Excellence & Mentorship

• Define and drive engineering best practices, ensuring code is testable, maintainable, and highly observable
• Balance the delivery of new features with the long-term health of our services, proactively identifying and addressing technical debt
• Mentor peers on the nuances of backend architecture, while actively seeking to learn from the team's expertise in data engineering and AI applications

Who You Are

• You are genuinely interested in how software can accelerate the transition to sustainable energy
• You can navigate complex codebases, dive into metrics and logs, and self-serve the answers needed to troubleshoot or innovate
• You thrive in a dynamic, collaborative environment where you might be building a traditional API one day and exploring an AI-driven data validation tool the next
• You are able to learn new concepts, tools, and technologies quickly
• You care about the people your software impacts, have a strong interest in aligning work and requirements with business outcomes
• You demonstrate respect and dignity for all people
• You are curious and have a growth-oriented mindset
• You are able to give and receive constructive feedback

Experience You'll Need

• 4+ years of professional experience in backend software engineering
• Deep proficiency in Kotlin or Java (or another modern OO language) with a strong grasp of design patterns and clean code principles
• Extensive experience building and maintaining APIs & services, specifically those involving complex business logic, high traffic, tight SLAs, or metadata management
• Professional experience working within cloud environments (AWS preferred)
• Ownership mindset with a firm understanding of monitoring, testing, and CI/CD pipelines
• Experience using AI tools to augment and accelerate feature development

Experience That's a Plus

• 2+ years building, maintaining, and optimizing data pipelines
• Full-stack development
• Distributed or asynchronous systems
• Multithreaded or parallel programming
• Experience with (or a desire to learn) Python and distributed processing frameworks like Spark
• Exposure to Databricks, Snowflake, or similar large-scale data environments.
• Familiarity with integrating AI/ML models into production services
• Experience in solar or distributed energy technology
• High-growth startup or fast-paced tech environment experience
• Experience with asynchronous and parallel processing frameworks such as Kotlin coroutines

Logistics

• Our office is in Escazú Village in San José
• We envision this as an in-office role, and we are very excited to build a vibrant environment where you can work alongside your colleagues from different teams.
• We value flexibility, and will work with you to craft a schedule that meets your needs. That could mean shifting your start time a bit to avoid rush hour traffic, or occasionally working remotely
• We plan to have this role start around early June
• We are unable to provide sponsorship for this role, now or in the future

Work-Life & Culture

• Culture of Growth: A collaborative environment with mentorship and opportunities for career advancement.
• Inclusive Community: Global affinity groups, supportive policies, and a commitment to diversity, equity, and inclusion.
• We are a passionate, mission driven team that believes in collaboration, mutual respect and trust. For examples, come Discover our Story!

Grow with Us

• We mentor and invest in our employees and prioritize them for future opportunities. Check out our Instagram reels to see a few career journey examples, or this Omnidian Career Experience overview on YouTube.

• Here are the roles in this career track:

  • Software Engineer I
  • Software Engineer II
  • Senior Software Engineer
  • Staff Software Engineer
  • Principal Software Engineer
  • Distinguished Software Engineer

• We're a fast-scaling growth company, which means we're constantly reinventing processes, adding new products, and asking people to use all of their skills and talents. That means there's going to be a lot of opportunities for you to grow, which also means you will likely be stretched in ways you've never experienced in a job before. If you are resilient, determined, and not afraid of a big challenge, come apply.
