Sr. Software Dev Engineer, Corporate Development Finance

The Investment Management System (IMS) is the system of record for Amazon's corporate investment and warrant portfolios — more than $200 billion in value across 700+ positions, spanning minority investments, the four corporate funds, and commercial-activity warrants. IMS serves teams across the Mergers & Acquisitions (M&A) ecosystem, including Corporate Development, Business Development, Accounting, Tax, Legal, and Treasury.

When someone needs to know what a holding is worth today, how much of a warrant Amazon has earned through its commercial deals, or simply what Amazon owns and what it's worth, IMS is where they get the answer. IMS data feeds directly into Amazon's financial statements and supports real-time investment decisions, so accuracy and timeliness are non-negotiable. A core part of this role is keeping IMS accurate, trustworthy, and current — continuously ingesting new deals and milestones, and integrating and regularly reconciling with other internal and external systems (Amazon Lantern, Accounting, Tax, Legal, Treasury, Factset).We

are a small, high-ownership technical team with a unique organizational structure: we sit within a larger finance team. This is a deliberate decision to embed technical expertise directly alongside finance partners, enabling rapid collaboration, troubleshooting, and delivery. As a result, this role requires close, effective collaboration and communication with both technical colleagues and non-technical stakeholders and team members. The role indexes high on visibility, ownership, and business acumen.

You will manage a team of 2 to 4 software developers - setting technical direction, unblocking the team, conducting code reviews, and raising the bar on engineering quality. You will design and build the services, data pipelines, and web application that power IMS, and you will own the programs that deliver them. That means working directly with stakeholders and leaders across the M&A ecosystem, translating their needs into clear requirements, and driving the work through to reliable, compliant outcomes.

You will drive the IMS roadmap end-to-end, prioritizing work, managing stakeholder expectations, and balancing near-term operational needs with longer-term platform investments. Tech stack: a serverless, event-driven backend on AWS (Python), a PostgreSQL database, a React web application, and an AI assistant built on Amazon Bedrock — all deployed through infrastructure-as-code and Amazon's internal CI/CD, with AI-assisted development tools used daily.

Key job responsibilities
• Own the architecture and the hardest technical problems in IMS, including the services and APIs that serve investment and warrant data, the quarterly data pipelines that carry positions from one quarter to the next, and the checks that catch when IMS and upstream finance systems disagree.
• Own the data model and the financial calculations (such as internal rate of return, unrealized value, and warrant vesting progress), and write the code and tests that the rest of the team builds on.
• Build the React web application that business users work in every day, and own the Amazon Bedrock–based AI assistant that lets them ask questions about the portfolio in plain language.
• Work directly with leaders across the M&A ecosystem to turn open-ended requests into concrete requirements, sequence the work, manage dependencies, and deliver each program. You own the outcome, not just your part of it.
• Run the deadline-bound work the team cannot miss, including the quarterly close.
• Lead integrations with partner data teams across multiple systems.
• Define infrastructure as code with AWS CDK, raise the bar in code and design reviews, and keep stakeholders and engineers aligned as work…
