Full Job Description

Role Overview

We are seeking a Senior Software Developer to design, build, and evolve agentic orchestrations, workflows, and internal toolsets that improve the efficiency, consistency, and quality of software delivery across the organization.

This role focuses on creating intelligent systems that help teams move faster while maintaining high engineering standards. You will work on tools and workflows used by software developers, QA engineers, product managers, product owners, engineering managers, and design partners to streamline the full software development lifecycle.

The ideal candidate is skilled in and motivated by AI and agentic systems, but grounded in strong software engineering fundamentals. Someone who cares about building tools that solve real problems, earning user trust, and measurably improving delivery outcomes.

Key Responsibilities

Design, develop, and maintain agentic orchestrations, automated workflows, and internal tools that improve software delivery outcomes.
Partner with QA, product management, product ownership, engineering leadership, and design to identify workflow bottlenecks and build solutions that improve collaboration and delivery quality.
Develop agent-based workflows that can coordinate multi-step tasks, interact with internal systems, use tools safely, and provide reliable, auditable outputs.
Establish patterns and best practices for building trustworthy AI-assisted software delivery tools, including guardrails, validation steps, human-in-the-loop review, and measurable quality controls.
Evaluate emerging AI, automation, and orchestration technologies and determine how they can be responsibly applied to software delivery.
Build reusable frameworks, services, APIs, and integrations that enable teams to automate common delivery activities.
Improve engineering effectiveness by reducing repetitive manual work, increasing consistency, and helping teams make better technical and product decisions.
Collaborate with security, compliance, and architecture stakeholders to ensure internal tools meet organizational standards for reliability, privacy, maintainability, and governance.
Perform occasional full-stack feature development within the context of the AI Toolset
Mentor and assist in the training and onboarding of new developers

Required Qualifications

5 or more years experience developing software in an Agile, team-based environment
BS and/or MS in a technical discipline (Computer Science or Software Engineering preferred)
Strong understanding of OOP concepts and design patterns
Expertise with Angular, ASP.NET Core, C#, JavaScript, TypeScript, CSS, SASS, and HTML
Experience with PostgreSQL or other relational databases, and Entity Framework Core or similar object-relational mapping frameworks
Experience building internal platforms, developer tools, automation frameworks, workflow engines, integrations, or productivity tools.
Strong understanding of the software development lifecycle, including planning, development, testing, code review, release management, and operational support.
Ability to design reliable, maintainable, and scalable software architectures.
Excellent communication skills with the ability to work effectively across engineering, QA, product, management, and design teams.

Preferred Qualifications

Experience building AI-assisted applications, LLM-powered tools, autonomous or semi-autonomous agents, or agentic workflow systems.
Familiarity with orchestration frameworks, tool-calling architectures, retrieval-augmented generation, prompt engineering, evaluation frameworks, or AI safety practices.
Knowledge of secure software development practices, privacy-aware system design, and governance for AI-enabled tools.
Experience working in healthcare technology, SaaS, regulated environments, or organizations with strong compliance requirements.

Success in This Role Looks Like

You dig deep to thoroughly understand our software development process, architecture and codebase organization.
You engineer tools, processes and workflows that meaningfully reduce friction in the software development and delivery process.
You improve the speed, quality, and consistency of work across development, QA, product, management, and design teams.
You create agentic workflows that are useful, reliable, explainable, and safe for teams to use.
You balance innovation with practical engineering discipline, ensuring that automation improves outcomes without creating unnecessary risk.
You help establish a foundation for how the organization responsibly applies AI and automation to software delivery.

Benefits

Competitive salary - $110,000-$135,000
Employer sponsored health, dental, vision, life, and disability insurance
Retirement plan with company contribution
Annual company profit sharing
Personal development/training budget
Open, collaborative work environment
Extensive 2-week onboarding plan
Comprehensive mentorship program
