Senior Platform Engineer - Cloud Infrastructure

About Mach Industries Founded in 2023, Mach Industries is a rapidly growing defense technology company focused on developing next-generation autonomous defense platforms. At the core of our mission is the commitment to delivering scalable, decentralized defense systems that enhance the strategic capabilities of the United States and its allies. With a workforce of approximately 350 employees, we operate with startup agility and ambition. Our vision is to redefine the future of warfare through cutting-edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security. The Role We are seeking a Senior Platform Security Engineer to lead security efforts across our growing Unmanned Aircraft Systems (UAS) portfolio. This role focuses on securing both hardware and increasingly software-driven systems, including autonomy platforms, command-and-control (C2) applications, APIs, cloud infrastructure, and embedded devices. As our products scale and become more connected, the attack surface expands across edge, air, and cloud environments. This role ensures security is built into the full system lifecycle—from hardware and firmware to applications and distributed services. Key Responsibilities Lead end-to-end product security across UAS platforms, including embedded systems, flight software, APIs, backend services, and cloud infrastructure. Design and implement secure architectures covering device identity, authentication, authorization, and data protection. Perform security assessments across software, firmware, and hardware, including application testing, code review, and adversarial analysis. Build and integrate security into CI/CD pipelines, including automated testing, scanning, and policy enforcement. Partner with software, hardware, and firmware teams to embed security into the development lifecycle. Secure communications

Discord has a highly engaged community of millions of daily active users who use the platform for many different reasons, but there’s one thing that nearly everyone does: play video games. Discord plays a uniquely important role in the future of gaming, and we are focused on making it easier and more fun for people to hang out before, during, and after playing games. More broadly, Discord is about empowering people to find belonging in all kinds of communities, and those people trust us to keep their communications safe. Our Platform Security Engineering team protects the systems we use to create Discord, making the "secure way" the "easy way." We're looking for a Senior Engineer to advance this mission through security expertise, software development, and operational excellence, with a particular focus on identity and access management: who and what can access Discord's systems, how they authenticate, and how access stays scoped to what's actually needed. You'll help identify leveraged opportunities to reduce security risk across Engineering, then design and deliver technical solutions: lovable "paved paths" for managing identities and access, shipping code, configuring cloud infrastructure, and operating services. If you're a security engineer with a deep interest in identity and access management, who's eager to own technically and socially complex projects, and excited to improve security and privacy at Discord, read on! This position is based in our San Francisco office. For this role, the Hiring Manager would like folks to be in the office 1-2 days a week. What you'll do Own software engineering projects end-to-end on a highly autonomous, horizontally integrated team with a lot of leverage. This is a code-forward role! Define what identity means for autonomous agents and other non-human actors at Discord (how they're provisioned, scoped, authenticated, authorized, and audited). As the role of these actors grows, and create primitives to implement that vision.

Altana is the network for trusted trade. Our AI-powered product network empowers governments and businesses to build a more resilient and secure global economy while keeping trade flowing. The Opportunity at Altana Altana is looking for a Principal Platform Engineer to be the technical authority for the platform our products run on. This is a senior individual contributor role, reporting to the Senior Director of Platform Engineering, for someone who steers architecture across organizational boundaries rather than inside one team's backlog. We operate a broad estate. Multi-cloud infrastructure across AWS and Azure, a multi-tenant commercial platform, accredited environments including FedRAMP and IRAP, and dedicated sovereign deployments for national customers. The architecture that holds those together determines how fast every product team can ship, how quickly a new customer comes online, and what our infrastructure costs. You will set the direction for it, and you will have real white space to go after the problems you judge to be the most consequential. You will be a permanent member of the Platform Engineering leadership team alongside our engineering managers, and you will be the person other engineers across the company come to when a technical question spans more teams than any one of them owns. Your Responsibilities Drive technical decisions and systems architecture across multiple organizations , not only within Platform Engineering, and contribute to company-wide design through existing forums while proposing new ones where they are missing Own the platform reference architecture across AWS and Azure and across our commercial, regulated, and sovereign environments, and define the patterns that engineering teams build against Translate company strategy into area-level technical strategy , keep it aligned with customer and product outcomes, and communicate the options and tradeoffs upward so leadership can choose with a clear view of the consequences Lead t
