Senior Software Developer

About Us

At Cambio Earth, we are changing the way infrastructure operators tackle climate resiliency. As an enterprise software and AI company with deep earth science expertise, built over 20 years as part of BGC Engineering, we work with customers to embed earth science intelligence into their critical infrastructure operations; helping to safeguard communities, essential services, and the environment.

Floods, landslides, seismic and extreme weather events are becoming more frequent, threatening the integrity of critical infrastructure. That's where we come in – and where you come in. Picture this: roads, railways, mines, pipelines, dams, levees – all protected by real-time situational awareness and insights that turn risks into manageable challenges.

The Cambio Earth team is passionate about making a difference. We love engaging directly with customers. We love building cutting-edge solutions that provide engineers and earth scientists new insights; ensuring the right risk-informed decisions are made at the right time.

The Role

As a Senior Software Developer, you'll help shape the foundation of our software systems as we transition from a distributed architecture to a streamlined, well-structured monolith with a disciplined relational schema. This work is focused on consolidation and clarity—simplifying complexity so our team can move faster and with confidence.

You'll design and implement the target architecture, establish schema discipline across the codebase, and lead our migration from SQL Server to PostgreSQL. Along the way, you'll collaborate with engineers and data specialists to create a backend that's predictable, well-modeled, observable, and easy to reason about—boring in the best way.

Responsibilities

• Define and evolve a modular monolith architecture with clear boundaries and explicit dependencies.
  
• Consolidate parts of the existing distributed system into the new architecture without disrupting functionality, and refactor services, models, and APIs to reduce duplication and complexity.
  
• Bring rigor to database design, including schemas, naming conventions, constraints, indexing, and migrations, and own the overall data model for core product domains.
  
• Establish patterns for safe schema evolution and collaborate with the Data Architect to keep backend and analytics schemas aligned.
  
• Lead the migration from SQL Server to PostgreSQL, including schema redesign, query refactoring, and performance tuning, and implement migration strategies with validation and rollback paths.
  
• Develop backend services and APIs that power web and mobile applications, integrate internal and external data sources, and maintain automated tests around critical business flows.
  
• Contribute to observability through logging, metrics, and diagnostics that make production behavior transparent.
  
• Work closely with other developers, QA, and product teams to deliver incremental, safe changes, participate in code reviews, and document architecture and migration plans for clarity and maintainability.
  

Required Education, Experience & Competencies

• Bachelor's Degree in Computer Science, Information Systems, Software Engineering, or a related discipline or equivalent experience.
• 7+ years of professional experience building and maintaining backend systems in production.
• Strong experience with relational databases: schema design, normalization, indexing, query optimization, and transaction semantics.
• Hands-on SQL expertise in at least one of SQL Server or PostgreSQL; ideally you've worked with both, or have done a migration between major RDBMSs.
• Solid experience with at least one backend language/framework (e.g., , C#/.NET, Python, or similar) and modern engineering practices (code review, CI/CD, automated testing).
• Experience working in a codebase that has real history (legacy behaviors, odd edges) and incrementally improving it instead of starting from scratch.
• Comfortable reasoning about and simplifying distributed systems: understanding where you can safely centralize logic and where you actually need distribution.
• Good communication skills: you can explain technical trade-offs to peers, document decisions, and collaborate across disciplines.
  

Nice to Have

• Direct experience consolidating microservices / distributed monoliths into monoliths or modular monoliths.
• Experience with PostgreSQL-specific features (e.g., JSONB, PostGIS, window functions) and how to use them judiciously.
• Familiarity with geospatial or time-series data and related patterns (though domain expertise can also be learned on the job).
• Experience in safety-critical or high-reliability domains (infrastructure, utilities, transportation, environmental, etc.).
