We are seeking a highly skilled Senior Software Engineer with strong experience in AWS architecture, C#, and modern engineering practices. In this role, you will design, build, and optimize critical systems that power high-volume financial applications. You will balance speed and quality, ensuring our platforms remain scalable, observable, and resilient as we continue to grow.

This is a hands-on development role-you will not simply maintain existing systems; you will design, develop, observe, and optimize the systems that support one of our most important products. Your work directly influences how quickly and reliably we deliver tax-optimized strategies, personalized indexing, and scalable portfolio management capabilities to clients.

For External Candidates:  Candidates must work in-office at one of the following locations for at least 3 days per week:
Omaha, NE;
Berwyn, PA.For Internal Candidates:  
* A*ll internal employees, regardless of their current work arrangement (remote or in-office), are encouraged to apply.
** What You’ll Do
*** Design and implement cloud-native services in AWS using C#, serverless patterns, containerized workloads, and event-driven architectures.
* Ensure systems are highly scalable, secure, observable, and automated, leveraging tools such as Cloud Watch, Open Telemetry, or equivalent observability platforms.
* Build high-quality, performant APIs and backend services with a heavy emphasis on clean architecture, testability, and operational excellence.
* Work with relational databases (MySQL, SQL Server, or similar) and contribute to schema design, query optimization, and performance tuning.
* Leverage or learn No

SQL technologies (e.g., Dynamo

DB, Document

DB) to support scalable, distributed patterns where appropriate.
* Partner closely with product, operations, analytics, and application development teams to deliver reliable features in a fast-moving Fin Tech environment.
* Collaborate effectively with offshore engineers, using asynchronous communication and overlapping work hours for real-time pairing and joint troubleshooting.
* Provide production support for business-critical systems, primarily during standard business hours, with occasional after-hours needs when incidents require it.
* Drive and uphold engineering best practices including CI/CD, code reviews, infrastructure-as-code, performance profiling, and continuous improvement.
* Use AI tools daily to accelerate development, enhance quality, and drive innovation as part of our AI-first engineering culture.
** What You Bring
*** 5–8+ years of software engineering experience, with deep expertise in C# and the broader .NET ecosystem.
* Strong understanding of AWS services and architectures, including Lambda, ECS/EKS, SQS/SNS, Step Functions, API Gateway, Dynamo

DB, IAM, VPC networking, and related patterns.
* Experience working with relational databases (SQL) and familiarity with No

SQL data modeling.
* Comfort designing and supporting high-scale, distributed systems, including performance tuning, caching strategies, failover design, and capacity planning.
* Proficiency with observability tools and best practices: tracing, metrics, logging, dashboards, alerting, SLOs/SLIs, error budgets, etc.
* Ability to balance speed and craftsmanship, writing code that is both efficient and maintainable in fast-paced environments.
* Strong communication skills and the ability to work productively with offshore teams, cross-functional partners, and non-technical stakeholders.
* A proactive mindset around production support, debugging, root cause analysis, and preventing incident recurrence.
* A passion for innovation and comfort using AI-driven development tools to improve velocity and quality.
** Why You’ll Love Working Here
