# Software Engineer 3 **Company**: MongoDB **Location**: New York City **Work arrangement**: hybrid **Experience**: senior **Job type**: full-time **Salary**: $106,000-$209,000 USD **Category**: Engineering **Industry**: Technology **Apply**: https://job-boards.greenhouse.io/mongodb/jobs/8348102?utm_source=yubhub.co&utm_medium=jobs_feed&utm_campaign=apply **Canonical**: https://yubhub.co/job/software-engineer-3-9afc7722-29d/ ## Description MongoDB's Application Modernization Platform (AMP) helps organisations modernise legacy applications and move their workloads and associated data from relational databases to MongoDB. The Agentic Integrations team builds the interfaces that let AMP capabilities be discovered, invoked, and orchestrated from AI agents and development environments. We are looking for a Software Engineer 3 to build and operate these integrations. ### Responsibilities - Design and implement agent and developer facing integrations for AMP services, including tool definitions, API clients, and the adapters between them - Define clear input and output contracts for each integration, including validation, error semantics, and behaviour when a call is malformed or only partially succeeds - Propagate authentication, authorisation, and tenant context across integration boundaries so that agent-invoked calls carry no more privilege than the user they act for - Build the instrumentation needed to observe agent-driven traffic, including structured logs, traces, latency and failure metrics, and actionable diagnostics - Write production-quality code and the unit, integration, and end-to-end tests that demonstrate correctness, including tests for nondeterministic model behaviour - Diagnose failures that span service, tool, and model boundaries, and drive them to root cause - Contribute integrations to shared SDKs, command-line tools, and agent frameworks used by other teams - Collaborate with product managers, platform engineers, and partner teams on scoped initiatives, and break work into incremental deliverables - Participate in code reviews, design reviews, and technical discussions that raise the quality of the team's work - Interview candidates and mentor engineers and interns ### Requirements - At least four years of experience building and operating production software services - Proficiency in a backend language such as Python, Go, Java, or TypeScript, with the judgement to work effectively in more than one - Experience designing APIs or service interfaces, including versioning, error handling, and backward compatibility - Practical experience with authentication and authorisation mechanisms such as OAuth, API keys, or service-to-service identity - Experience with automated testing, continuous delivery, and debugging in distributed systems - Strong written and verbal technical communication skills - A collaborative approach and the ability to make realistic assessments of project complexity and delivery risk ### Nice to Have - Experience building tool or integration surfaces for AI agents or large language models, including execution context, tool schemas, or guardrails against nondeterministic behaviour - Experience with the Model Context Protocol or a comparable agent-to-tool integration standard - Experience shipping developer tooling such as CLIs, SDKs, or local servers that run inside customer-managed environments - Familiarity with application modernisation, relational databases, MongoDB, or automated code transformation - Experience working with customers or field teams on integration and deployment issues - Experience mentoring engineers or interns and contributing to technical hiring ### What Success Looks Like - In your first month: Build a working understanding of AMP's architecture, the team's integration patterns, and the development and testing workflow. Ship small, well-scoped integration fixes and contribute effectively to code reviews. - In your first three months: Own delivery of an integration for one AMP capability, from interface definition through production rollout. Establish the tests and telemetry that let the team detect and diagnose failures in that integration. - In your first six months: Take regular ownership of code reviews and participate meaningfully in design reviews for agent-facing interfaces. Independently drive a scoped technical project from investigation through implementation and validation, coordinating with the partner team that consumes it. - In your first twelve months: Lead the development of a substantial integration or reusable component that other teams adopt. Help mentor new engineers and contribute to the team's integration standards and technical direction. ### Benefits MongoDB offers a range of benefits, including: - Competitive salary ($106,000 - $209,000 USD) - Equity - Participation in the employee stock purchase programme - Flexible paid time off - 20 weeks fully-paid gender-neutral parental leave - Fertility and adoption assistance - 401(k) plan - Mental health counselling - Access to transgender-inclusive health insurance coverage - Health benefits offerings For more fresh new jobs, check out [yubhub.co](https://yubhub.co/). ## Skills ### Required - Python - Go - Java - TypeScript - API design - authentication - authorisation - testing - debugging ### Nice to have - AI agents - large language models - Model Context Protocol - developer tooling - application modernisation - relational databases - MongoDB --- Source: [Apply at job-boards.greenhouse.io](https://job-boards.greenhouse.io/mongodb/jobs/8348102?utm_source=yubhub.co&utm_medium=jobs_feed&utm_campaign=apply)
