Role Summary
The Software Engineer Sr. Specialist serves as a hands‑on technical leader supporting Sales and Marketing Technology. This role designs, builds, and evolves scalable, secure, and integrated solutions across SaaS platforms (including Salesforce), custom applications, integrations, and applied AI capabilities.
This role is ideal for a senior developer who enjoys building production systems and guiding other engineers, and who is ready to take on increased technical leadership and progressively expand into broader solution design and architectural responsibility over time. You do not need to come into the role as a formal architect, but you should be comfortable leading technical decisions for complex features, integrations, or systems.
The Sr. Specialist actively develops production solutions while mentoring engineers, improving platform quality, and influencing technical direction—particularly around practical, responsible use of AI within Sales and Marketing workflows.
This role reports to IT Manager - Software Engineering - Application Delivery.
This hybrid position will be based out of our Kansas City, Missouri office.
This position is not eligible for visa sponsorship. Applicants must be authorized to work in the U.S. without visa sponsorship, now or in the future.
How You Will Make an Impact
Design and build end‑to‑end solutions across applications, integrations, AI, security, and operations
Lead technical design for complex features and integrations, collaborating with architecture and platform teams as needed
Actively contribute high‑quality code while guiding other engineers through reviews, pairing, and design discussions
Help establish shared technical patterns, practices, and guardrails that allow the team to move faster safely
Drive practical, responsible application of AI to improve workflows, insights, and developer productivity
Evaluate SaaS platforms, APIs, and tools; contribute to POCs and technical recommendations
Maintain and evolve the health of the existing tech stack by reducing technical debt and improving reliability, observability, and performance
Partner with engineering, security, enterprise architecture, and vendors to deliver scalable and compliant solutions
Examples of impact may include Salesforce integrations, API‑driven services, middleware‑based workflows, data pipelines, event‑based architectures, or AI‑assisted automation embedded into existing platforms.
What We Mean by Technical Leadership
Technical leadership in this role is demonstrated through action and ownership, not just title. This includes:
Owning challenging problems from design through implementation
Making pragmatic tradeoffs and clearly communicating technical decisions
Improving systems incrementally rather than over‑engineering up front
Mentoring engineers and helping raise the overall technical bar
Knowing when to proceed independently vs. when to seek architectural or security guidance
What You Bring to the Team (Required)
Bachelor’s degree in Computer Science, Information Technology, or related field, or equivalent professional experience
8+ years of software engineering experience
Demonstrated experience leading technical solutions for complex features, integrations, or systems (as a senior engineer, staff engineer, tech lead, or similar role)
Strong hands‑on development experience with modern application stacks (Java/Spring, JavaScript/TypeScript, React, Node.js, or similar)
Experience designing, consuming, and troubleshooting APIs in service‑based or event‑driven architectures
Hands‑on experience developing on or integrating with Salesforce (Apex, Lightning Web Components, APIs), or strong experience integrating enterprise platforms into Salesforce‑centric ecosystems
Ability to clearly communicate technical decisions to both technical and non‑technical stakeholders
Demonstrates the American Century Investments Winning Behaviors: Client Focused, Courageous and Accountable, Collaborative, Curious and Adaptable, Competitively Driven.
Applied AI & Automation
Experience applying AI tools or services to real‑world workflows (e.g., automation, insights, content assistance, developer productivity), or
Strong interest and demonstrated curiosity in learning and responsibly applying AI
Awareness of considerations such as data handling, security, quality, and rollout risk
Willingness to partner with security and architecture teams where AI usage impacts governance or compliance
Ownership of enterprise‑wide AI strategy is not required—this role focuses on practical application and learning.
Additional Assets (Preferred)
Experience working in regulated or risk‑sensitive environments
Salesforce experience across Sales Cloud, Marketing Cloud, Data Cloud, or related platforms
Middleware or integration platform experience (e.g., MuleSoft, Informatica)
Cloud‑native development experience (containers, Kubernetes/OpenShift, CI/CD)
Observability tooling experience (e.g., Datadog, Prometheus, Grafana)
Prior participation in architecture reviews, platform standards discussions, or technical governance forums
Why This Role Is Different
This is neither a purely architectural role nor a ticket‑only delivery role.
It’s an opportunity for a senior engineer who:
Wants to stay hands‑on
Enjoys mentoring and guiding others
Is ready to expand technical leadership and architectural influence over time
Wants to work on meaningful Sales and Marketing platforms, including thoughtful AI adoption
If you’re already leading technical decisions informally and looking for a role that supports your growth into broader ownership, this role is designed for you.
