About This Position

We are searching for a Senior Software Engineer to join our Fenix24 product team. In this role, you will be responsible for building scalable, cloud-native services that process infrastructure, backup, and asset telemetry data streams and deliver valuable insights to our customers. Your focus will be primarily backend, with opportunities to work across the full stack. Our team operates with the speed and ownership of a startup, backed by the stability of an established company.

Our team has fully embraced AI-assisted, agentic development, guided by a core principle: agentic workflows scale execution, but they don’t always scale judgment. That judgment is what our engineers bring. We spend less time writing code by hand and more time understanding the problem, directing AI tools, and making sure what they produce is right, so we can move fast and in the right direction.

As a Senior Software Engineer, you will lead the delivery of significant features from requirements through release, take long-term ownership of key areas of the platform, and help raise the bar for engineering practices across the team.

Key Responsibilities

• Take end-to-end ownership of software delivery: partner with product to define requirements and success criteria, break work into iterative deliverables, and coordinate contributions from other engineers through release
• Design, implement, and optimize scalable services and data pipelines on Azure that turn resiliency-relevant data from backup, hypervisor, EDR, and cloud sources into actionable insights
• Build reliable integrations with third-party APIs, including handling authentication, rate limits, pagination, and changes in upstream data formats
• Use agentic coding tools as a core part of your daily workflow, providing clear context and direction and critically evaluating generated code for sound architecture, design, and logic
• Serve as a long-term owner of key platform components, ensuring their ongoing health, reliability, and maintainability through robust monitoring, logging, and proactive improvement
• Contribute to planning with a view beyond the immediate task, identifying risks, dependencies, and technical unknowns early
• Foster a culture of learning and improvement by mentoring other engineers, providing feedback, and actively participating in retrospectives to help the team continuously improve how it plans, communicates, and delivers
• Collaborate closely with product, design, and engineering teammates to ensure requirements are met and features are delivered on time
• Other duties as required

Qualifications, Requirements & Preferred Skills

• Bachelor’s degree in Computer Science or a related field, or equivalent experience, is preferred
• 5+ years of professional software development experience in Python or a statically typed language such as C#, Java, C++, or Rust. Working knowledge of Python is required
• Solid grounding in system design, with experience designing and building services, APIs, and data pipelines in a cloud environment, including microservices and distributed systems
• Hands-on experience using AI coding agents to build and ship software, with a clear understanding of how to guide them effectively and evaluate their output
• Proven experience leading the delivery of features or projects involving multiple engineers, from requirements definition through release
• Experience working on agile teams, delivering iteratively, and contributing to a culture of continuous improvement
• Experience with automated testing and CI/CD pipelines for building, testing, and deploying code
• Strong understanding of security best practices, especially as they relate to data protection, authentication, and secure coding principles
• Ability to work effectively on a fully remote team
• Hands-on experience with our technology stack, particularly Azure and our data platforms:
  • Backend: Python, Rust
  • Frontend: TypeScript, Vue.js
  • Cloud: Microsoft Azure (Function Apps, containers, and supporting Azure services)
  • Data: Databricks, Delta Tables, PostgreSQL, Azure Cosmos DB
  • Infrastructure and Delivery: Bicep, Azure Pipelines, Azure DevOps
  • AI Tooling: Anthropic Claude
• Industry experience in cybersecurity or familiarity with common security practices and frameworks
• Experience across multiple languages and technology stacks and interest in working across both backend and frontend
• Background working on an early-stage or fast-moving software product
• Excellent analytical, organization, and problem-solving skills
• Demonstrated strong written and oral communication skills, including strong relationship building skills and leadership capabilities
• Ability to form relationships across all levels of the company while modeling Fenix24’s Culture and Values
