We are looking for a Software Development Engineer III to join our team at Amazon and help shape the technical direction of critical software systems. In this role, you will lead complex projects from concept through delivery, working across the full software lifecycle to solve problems where the business need is clear but the right technical approach is still yours to define. You will design and build solutions that balance performance, scalability, and long-term maintainability while collaborating with engineers and stakeholders across multiple teams. If you are a self-starter who thrives on turning ambiguity into well-architected systems and who enjoys mentoring others along the way, we want to hear from you. ### Key job responsibilities - Lead the design, implementation, and delivery of multi-engineer software projects, owning your team's architectural direction and ensuring solutions are scalable, performant, and secure. - Define and drive engineering best practices across your team, including code quality standards, operational readiness, and development processes that improve productivity and reliability. - Collaborate with cross-functional partners — including product managers, technical program managers, and engineers on related teams — to align on requirements, resolve technical trade-offs, and deliver integrated solutions. - Mentor and coach engineers on your team and beyond, providing technical guidance on system design, coding practices, and career development to strengthen overall team capability. - Evaluate and integrate new technologies, design patterns, and generative AI tools where appropriate to simplify systems, reduce complexity, and accelerate delivery. ### A day in the life You might start your morning reviewing a design document from a teammate, offering feedback that sharpens the approach before a broader review. By mid-morning, you are deep in code — prototyping an interface that defines the boundary between two critical components. After lunch, you join a cross-team architecture discussion to align on a shared dependency, then pivot to pair-programming with a junior engineer who is tackling a tricky edge case. Your afternoon wraps up with a quick look at operational dashboards, ensuring your services are healthy and your alarms are well-tuned. ### About the team Our team builds software that matters to AWSs customers at a global scale. We value clear communication, pragmatic problem-solving, and an inclusive environment where every engineer's perspective is heard. We invest in each other's growth through mentorship, constructive code reviews, and knowledge sharing. As we look ahead, we are focused on simplifying our systems, adopting new technologies thoughtfully, and raising the bar on operational excellence. If you want to work alongside collaborative, curious engineers who care about building things the right way, this is the team for you. ## At a glance - Posted by the employer: Oct 20, 2026 - First seen by OpenNash: Oct 25, 2026 - Last checked: Nov 1, 2026 - Listed for: 12 days - Location: US, TX, Dallas[Apply on Amazon’s careers site →](https://www.amazon.jobs/en/jobs/10584444/software-development-engineer-iii-afx-planning-tools) ## Hiring at Amazon - Open jobs: 19,174 - New in the last 7 days: After two weekly collections - Tracked since: Jul 10, 2026 [All Amazon jobs](https://jobs.opennash.com/companies/amazon/) · [Weekly hiring report](/reports/hiring/) ## More jobs at Amazon ### [Business Developer OSS and BSS, Telco GTMS](https://jobs.opennash.com/companies/amazon/jobs/de040b0e23fa9bf00675/) US, TX, Dallas ### [Salesforce Developer II, AWS, AWS AFX Planning Tools](https://jobs.opennash.com/companies/amazon/jobs/3d8e019b116046fca2a0/) US, TX, Dallas ### [Senior Delivery Consultant- DevOps, Worldwide Public Sector Professional Services, FedFin](https://jobs.opennash.com/companies/amazon/jobs/f8d7a6300f7304cea1f9/) US, TX, Dallas ### [Senior Software Dev Engineer, Enrollment Experience - Benefits Experience & Technology (BXT)](https://jobs.opennash.com/companies/amazon/jobs/6127649e12126621b5cf/) US, TX, Dallas ### [Software Dev Engineer II - AMZ26546.2](https://jobs.opennash.com/companies/amazon/jobs/bf1dd9199290b2d71471/) US, TX, Dallas ## Similar jobs at other companies ### [Software Development Engineer III](https://jobs.opennash.com/companies/optimum/jobs/3fea6604c9aa98bcc956/) Optimum · Bethpage, NY, US ### [Software Engineer III - Platform Tooling Development](https://jobs.opennash.com/companies/jpmorganchase/jobs/87427a350c37a900426d/) JPMorganChase · Plano, TX, United States ### [Software Development Engineer III](https://jobs.opennash.com/companies/optimum/jobs/3e9aa0dc9c49cb60c459/) Optimum · Bethpage, NY, US ### [Software Engineer III - Trading Platform Development](https://jobs.opennash.com/companies/jpmorganchase/jobs/91229144423bb911664e/) JPMorganChase · Jersey City, NJ, United States ### [iOS Software Engineer III](https://jobs.opennash.com/companies/alphabet/jobs/c94e7b2b04a8af471830/) Alphabet · Boston, Massachusetts OpenNash lists jobs from employers’ own careers sites and does not handle applications.
