Job description

About the Company:

Stable Kernel is a technology services firm and custom software developer building scalable software solutions for cutting-edge, innovative enterprises to move their business forward. We are headquartered in Atlanta, GA.

We're a privately held, Great Place to Work Certified Company™ with a multi-award-winning culture and an impressive 10-plus-year trajectory of sustainable growth. At Stable Kernel, we support our employees in ways that help them do some of the best work of their lives.

About the Role:

As a Stable Kernel Senior Software Engineer , you play an essential role in setting our portfolio of world-class clients up for success through the development and delivery of their most innovative, transformational initiatives. You will collaborate daily with other engineers and product team members, make decisions that influence the path of a product roadmap, leverage software development best practices, and become a more well-rounded engineer as you learn new technologies. Your knowledgeable practice, reliability, and consultative nature make you an engineer that stakeholders and teammates trust.

Senior Software Engineers may be classified as individual contributors or people managers with individual contributor responsibilities.

Core Responsibilities Include:

Technical Impact:

• Designing and implementing scalable, maintainable React Native components and screen flows that serve both iOS and Android from a shared codebase.
• Establishing and evolving the front-end architecture, including state management patterns, navigation structure, and shared component libraries.
• Defining and enforcing code quality standards through pull request reviews, linting rules, and automated checks.
• Building and maintaining integrations with RESTful APIs and backend-for-frontend (BFF) services, including error handling, caching, and offline-resilient patterns.
• Collaborating with design to implement UIs, animations, and interaction patterns that feel native on both platforms.
• Designing test strategies and owning CI/CD pipeline reliability for mobile builds, including unit, integration, and end-to-end testing.
• Identifying and resolving performance bottlenecks, including render optimization, memory management, and startup time improvements.
• Providing expert feedback that improves the overall delivery of work.
• Ensuring a high standard of quality across the project.
• Using AI-assisted development tools such as Claude Code or Cursor to accelerate delivery while maintaining code quality and architectural standards.

Business Alignment:

• Understanding the client's business and goals and using them to improve the definition of teams' projects.
• Identifying opportunities to provide additional value for our clients by suggesting and delivering improvements based on observations.
• Contributing to the estimation of work for high-level planning and costing that clearly identifies gaps, risks, and assumptions.

Interacting with Others:

• Coordinating with people outside your team, including product and design leadership.
• Influencing the roadmaps of other teams, especially to get work prioritized that's required for your own team.
• Advising people across the Director and VP-levels of the organization.
• Reporting status for the whole team with a general understanding of where each member's work is.

Autonomy & Ambiguity:

• Designing and supporting long-term roadmaps with limited direction and requiring no direction on project plans.
• Considering and planning around cross-team dependencies to most effectively break down work across the team.
• Working within ambiguity to define and break down challenging projects (e.g., projects that are hard to derive benefits from until the end of the project, projects that are very large, or projects that have a lot of uncertainty or require novel solutions).

Problem-Solving:

• Analyzing the effectiveness of decisions and demonstrating accountability for outcomes.
• Making trade-offs between short-term and long-term solutions.
• Evaluating trade-offs others are making.
• Anticipating, recognizing, and mitigating risks to prevent potential roadblocks.
• Escalating issues and bringing recommended solutions to the table.

Leadership:

• Taking ownership and contributing to process improvements that positively impact the work.
• Advocating for best practices across your project or client program.
• Mentoring junior and intermediate colleagues by helping them grow professionally.
• Setting a positive example by using our company values and imperatives as a north star.
• Providing regular constructive feedback.
• Resolving conflicts.
• Guiding less experienced colleagues through complex projects.
• Leading team learning sessions.
• Leading projects.
• Demonstrating strong project roadmapping skills, including planning, delegating, and monitoring progress.
• Making critical decisions and driving projects to successful completion.
• Representing the team in client conversations.
