We are seeking a Core Platform Developer to help design and build shared engineering foundations used across the firm. This role is focused on backend and platform capabilities that improve how internal teams build, integrate, deploy, and operate software.
The ideal candidate is a strong software engineer with platform instincts: someone who can build reusable services, frameworks, and tooling that improve developer productivity, standardize common patterns, and increase the reliability of internal systems. This person should be comfortable working across multiple areas of the stack, from service frameworks and API enablement to observability, governance, and developer workflows. This is a high-ownership role within a global, fast-moving engineering environment.
Key Responsibilities- Design and build shared backend services, frameworks, and developer tooling that support internal application and service development.
- Develop common platform capabilities such as service templates, authentication and authorization patterns, API standards, observability integrations, error handling, and shared runtime utilities.
- Improve the developer experience through better tooling, automation, documentation, onboarding patterns, and paved-road workflows for engineering teams.
- Help define and evolve standards for service architecture, API design, deployment, monitoring, and operational support.
- Build reusable libraries and platform components that reduce duplication and promote consistency across teams.
- Partner with application developers, infrastructure engineers, security teams, and other stakeholders to understand requirements and deliver practical, scalable solutions.
- Contribute to adjacent platform needs as priorities evolve, including internal tooling, service governance, and reliability-focused capabilities.
- Support adoption of shared platform capabilities by reviewing designs, guiding implementation, and helping teams integrate with standard approaches.
- Contribute to CI/CD, debugging, production support, and ongoing operational improvement of shared systems.
- Explore and integrate AI-assisted developer workflows where they can meaningfully improve engineering productivity and quality.
- 6+ years of software engineering experience, with significant experience in backend systems, platform engineering, or internal developer tooling.
- Strong programming skills in Python, with the ability to design and build production-quality services and tooling.
- Experience building and maintaining backend services, APIs, and shared engineering components in complex environments.
- Solid understanding of service architecture, API design, authentication and authorization, logging, monitoring, and error handling.
- Hands-on experience with backend frameworks such as FastAPI, Node.js, or similar technologies.
- Familiarity with cloud-native development, including Docker, Kubernetes, CI/CD pipelines, and cloud infrastructure, preferably AWS.
- Experience designing systems for reliability, maintainability, and scale across multiple consuming teams.
- Strong communication skills and the ability to work effectively across engineering teams with different needs and levels of maturity.
- Experience building or supporting shared engineering platforms, internal developer tooling, service frameworks, or common backend infrastructure.
- Familiarity with developer enablement patterns such as service templates, internal portals, reusable libraries, or governance workflows.
- Experience improving observability, production support, and operational standards across multiple services or teams.
- Exposure to AI/LLM-enabled developer workflows, internal copilots, or automation tooling.
- Experience in financial systems, regulated environments, or other high-reliability domains is a plus.
