Senior Software Engineer

Skillable is a 100% remote technology company modernizing training through skills-based learning solutions. The Senior Software Engineer owns projects and systems end-to-end, designing, building, and maintaining server-side infrastructure, client-side interfaces, APIs, databases, and design systems for custom labs and related applications. The role also leads AI-assisted engineering practices, automated testing, technical quality, cross-functional collaboration, and mentoring.

Responsibilities:

• Design, scope, and decompose complex software features into well-defined implementation plans, leveraging AI-assisted development workflows to accelerate delivery while maintaining engineering rigor
• Guide and direct AI agents through feature development, serving as the primary architect, reviewer, and decision-maker to frame the problem, set constraints and make the calls that ensure solutions are aligned with business requirements and technical standards
• Build effective scaffolding that enables AI tools to generate high-quality, maintainable, and scalable code, project context management, reusable skills, agent workflows, prompt frameworks and automated quality checks
• Drive comprehensive automated testing and verification practices for every feature before release, ensuring unit tests and validation scenarios are tied back to the requirements
• Own the quality of all delivered software by rigorously reviewing AI-generated output, challenging assumptions, finding the gaps, and validating that solution fully resolves the problem
• Identify and mitigate risks associated with AI-assisted development, ensuring generated solutions meet expectations for security, maintainability, correctness, and long-term sustainability
• Continuously raise the team capabilities in AI-driven engineering by improving workflows, tooling, agents and best practices other engineers depend on for quality outcomes
• Create and maintain documentation of features, design decisions, configurations, and other key technical areas of the application
• Resolves ambiguity and turns ambiguous problems into defined, scoped work for themselves and others
• Actively collaborate with other developers, QA engineers, designers, and product experts in a cross-functional scrum team
• Assist with scope and estimation for proposed features, leading to accurate cost and timeline estimates
• Propose, prototype, and champion technologies and processes that continuously help Skillable advance integration solutions
• Mentor other members of the software team to foster skill development and knowledge sharing
• Establish quality development patterns and practices, ensuring the team adheres to these standards
• Communicates technical decisions clearly and gives feedback to peers in code reviews and beyond
• Propose alternate designs that improve time-to-market or reduce cost or complexity
• Explore and recommend new technologies, patterns, and methods to accomplish items on the technical and product roadmaps
• Recommend standards and best practices for non-functional requirements such as system performance, usability, reliability, adaptability, security, legal and other operational aspects
• Participate in team on-call rotation during evenings, weekends, or holidays for emergency support or special events
• Consistently review work to ensure quality, avoid errors and maintain high standards
• Contribute to interviewing and selecting new team members
• Support and promote the company values through positive interactions with both internal and external stakeholders on a regular basis
• Other strategic business initiatives or special cross-functional project involvement as required

Requirements:

• Bachelor's degree in related field (computer software, computer science, software development, etc.) or equivalent work experience
• 8+ years of professional experience as a software developer in an agile product team
• 5+ years working with .NET Framework and C# required, AND Typescript or JavaScript required
• Hands on experience delegating real implementation work to AI agents and reviewing and verifying what comes back for delegated engineering, not autocomplete
• Proven experience regularly use of modern AI tools/agent tools including GitHub CoPilot and Claude Code or similar as a standard practice in building software that is not experimental
• Strong fundamentals in system design, debugging and code review so AI raises the bar for, supporting existing coding skills
• Exceptional judgment in AI-generated output, preventing pursuits of ineffective solutions and technical dead ends and ensuring course correction early
• Demonstrated experience in MSSQL and Entity Framework
• Proficiency in collaborating with UX designers to translate designs into working software
• Proficiency in creating and consuming RESTful APIs
• Proficiency in Unit Testing, including writing comprehensive, maintainable, and efficient test cases to ensure code correctness, reliability, and performance
• Experience working with cloud native applications
• Proactively addresses challenges, seeking opportunities for continuous improvement
• Self-motivation and the ability to contribute effectively with minimal supervision, within a collaborative team environment
• Ability to adapt to dynamic project needs while maintaining quality and focus
• Ability to participate in team on-call rotation during evenings, weekends, or holidays for emergency support or special events
• Experience working with hands-on technical training environments, virtual labs, or learning platforms is highly desirable
• Evidence of building scaffolding around AI tools: custom agents, MCP servers, eval harnesses or enablement that made AI work more efficiently for a team or department, strongly preferred
• Experience with the following is appreciated but not strictly required: Authentication (e.g., OIDC, OAuth, SAML), NextJS, ExpressJS, and Building pipelines and DevOps practices
