Job Description:

Fidelity Labs is adding a principal-level Engineer to our Boston Seaport headquarters at Commonwealth Pier.

Are you interested in joining a dynamic, innovation-focused, and high impact team? Do you enjoy building new products and services in a collaborative, fast-paced environment? Join Fidelity Labs, our in-house new business incubator, as a Principal Engineer of application Architecture for an early-stage SaaS platform targeting the Charitable sector. In this role, you will own the technical vision and architectural direction for a modern, cloud-native platform - while also serving as a key technical resource to the engineering team. The engineering team delivers next-generation software application enhancements and new products for a changing world. Working at the cutting edge, we design and develop software for platforms, applications and diagnostics - all with the most advanced technologies, tools, software engineering methodologies and the collaboration of internal and external partners.

The Role

As a Principal Engineer, you will own the end-to-end technical architecture for Foundation Services - a modern SaaS platform built on Angular, Java Spring Boot, and AWS. You will report to the Director of Architecture and serve as a senior technical resource across the engineering team, contributing architectural decisions, setting standards, and providing deep subject-matter expertise across the full software and infrastructure stack. You will also collaborate closely with engineering, contributing code and collaborating on matters of API standards, coding best practices, DevOps strategy, and technical excellence.

Lead architecture design and decision-making across frontend (Angular), backend (Java Spring Boot), cloud infrastructure (AWS), and data tiers (YugabyteDB), producing well-reasoned Architecture Decision Records (ADRs)
Define and evolve the platform's system architecture - including Experience APIs, Domain APIs, authorization models, workflow engines, and cloud resiliency strategies - aligned with enterprise standards and the well-architected framework
Establish and enforce engineering standards for API design, Spring Boot patterns, code quality, and security, ensuring consistent, maintainable implementations across squads
Collaborate with Product, UX, and Engineering leadership to translate complex business requirements into scalable, secure, and maintainable technical solutions
Collaborate with Engineering to provide subject-matter expertise on Spring Boot, RESTful API standards, coding best practices, and DevOps tooling and pipelines
Partner with enterprise architecture teams to ensure alignment with Fidelity's broader technology strategy, security requirements, and compliance posture
Evaluate new technologies and conduct technical spikes to inform platform evolution and upcoming architectural decisions
Mentor and guide engineers across the team, fostering a culture of technical rigor, continuous improvement, and ownership

The Expertise and Skills You Bring

10+ years of professional software engineering experience, with at least 4 years in a principal architect or senior technical leadership role
Deep expertise in Java Spring Boot, RESTful API design, and enterprise application architecture patterns
Strong frontend architecture knowledge, including Angular, component design, and modular application structures
Proven experience designing cloud-native solutions on AWS, including multi-region resiliency, infrastructure strategy, and the AWS well-architected framework
Hands-on experience with relational and distributed database systems; familiarity with active/active database strategies (e.g., YugabyteDB or similar)
Experience producing Architecture Decision Records (ADRs) and driving technical decisions collaboratively with cross-functional stakeholders
Solid understanding of DevOps practices, CI/CD pipelines, and infrastructure-as-code concepts
Excellent communication skills with the ability to convey complex architectural concepts to both technical and non-technical audiences
High degree of ownership and autonomy; able to drive long-horizon technical strategy with minimal direction
Experience with workflow engine design or BPM platforms, like Temporal, Camunda, or similar is a plus
Familiarity with Fidelity enterprise tooling, including the Fidelity Developer Toolkit or related SDKs is a plus
Prior work in a startup or incubator environment, defining architecture from the ground up is beneficial
Experience with authorization patterns, fine-grained access control, and enterprise security standards in a SaaS context is a plus
Background in fintech or financial services platforms, particularly charitable giving or wealth management domains is a plus

The Team

We are Fidelity Labs, Fidelity Investments’ in-house fintech incubator with a mission to build new businesses to drive growth for Fidelity. We seek to shape the future of our industry by building new products and services to improve the lives of the diverse set of customers, businesses, and financial institutions we serve.

Fidelity Labs is a dynamic workplace that combines the best parts of startup life - building from scratch, adapting quickly, and moon-shot ambition - with the scale and stability of an industry leader. We provide a safe space for startup teams to explore new business ideas, quickly test them with customers, and scale the most promising concepts within an existing business unit, or as a new venture.

This opportunity is brought to you by Fidelity Labs. Learn more at labs.fidelity.com.
