Software Dev Engineer II, AWS Networking (MONA)

• Own the design, implementation, and operation of well-scoped components and features of our in-house network software - controllers, SDN, planning software, and out-of-band systems - end-to-end.
• Turn ambiguous requirements into high-quality, well-tested, scalable code; contribute to design docs and design reviews.
• Operate your services in production and uphold high operational standards, improving monitoring and alarming as you go.
• Drive correctness and safety for automation that acts on production networks: idempotency, guardrails, and observability that proves work actually happened.
• Collaborate with your team and partner teams to evolve the product and continuously improve code, processes, and quality.
• Mentor junior engineers and contribute to the team through thoughtful code reviews.
• Participate in the on-call rotation for the services you own.

A day in the life

You own a component end-to-end: you write the design, build it, ship it, and operate it. One morning you are extending our controller for agentic network auto-remediation; the next you are improving how the planning software allocates ports and capacity for a new data center build. You will make a teammate’s change better in review, tighten operational excellence on your service, and help a junior engineer level up - all on systems that run at a scale almost nowhere else can offer, with real ownership and teammates sharp enough to make you better.
