Principal Software Engineer

About Us: 

eSimplicity is a modern digital services company that partners with government agencies to improve the lives and protect the well-being of all Americans, from veterans and service members to children, families, and seniors. Our engineers, designers, and strategists cut through complexity to create intuitive products and services that equip federal agencies with solutions to courageously transform today for a better tomorrow.? 

Purpose and Scope: 

We are hiring a Principal Engineer to lead hands-on delivery of a public-facing mobile application incorporating map-based search, with sensitive data, robust accessibility requirements, and high requirements for long-term maintainability. This role is not advisory-only: you will design, build, and operate production software, while setting technical direction and quality bars for the system as it evolves.

You will work closely with product, design, and security stakeholders to translate policy and operational requirements into durable technical solutions. The work emphasizes secure data intake, WCAG-compliant user experiences, disciplined API design, and modern continuous delivery practices appropriate for a county government environment. You are expected to be comfortable making architectural tradeoffs, owning production outcomes, and mentoring other engineers through example. 

This role is contingent upon award. 

Responsibilities: 

• Design, build, and maintain backend services and APIs supporting user intake, data validation, persistence, and administrative workflows. 
• Own backend architecture decisions, including data models, service boundaries, and integration patterns. 
• Implement secure application logic for systems handling sensitive data (PII/PHI), including authentication, authorization, session management, and audit logging. 
• Design and maintain versioned, well-documented APIs with explicit data contracts and validation rules. 
• Support mobile and web clients by providing performant, reliable backend services and clean integration surfaces. 
• Contribute to frontend implementation as needed to enable end-to-end delivery, with awareness of accessibility and mobile constraints. 
• Build and maintain CI/CD pipelines, infrastructure-as-code, and automated tests to support frequent, low-risk deployments. 
• Instrument backend services for observability, reliability, and performance; diagnose and resolve production issues. 
• Operate effectively within public-sector compliance environments, including HIPAA, accessibility, records retention, and audit requirements. 
• Provide hands-on technical leadership through code reviews, architectural guidance, and direct contribution to production code. 

Required Qualifications: 

• 12+ years of progressive software engineering experience, including architecture ownership of production systems at scale and experience delivering mobile-first solutions and integrating GIS or map-based data into frontend applications. This keeps the bar high while avoiding unintended inflation. 
• Architecture ownership at scale
• Long-term technical direction
• Production accountability
• Elevated decision authority

Desired Qualifications:  

• 3+ years of experience implementing map-based search or similar functionality in a consumer web application 

Working Environment: 

eSimplicity supports a remote work environment operating within the Eastern time zone so we can work with and respond to our government clients. Expected hours are 9:00 AM to 5:00 PM Eastern unless otherwise directed by your manager.  

Occasional travel for training and project meetings. It is estimated to be less than 5% per year.  

Benefits:  

We offer a highly competitive salary and full healthcare benefits. 

Equal Employment Opportunity:  

eSimplicity is an equal-opportunity employer. All qualified applicants will receive consideration for employment without regard to race, religion, color, national origin, gender, age, status as a protected veteran, sexual orientation, gender identity, or status as a qualified individual with a disability.
