Mission Systems Engineers Jobs

SpaceXAI’s mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company’s mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates. ABOUT THE ROLE: Agencies decide what gets planned, pitched, and bought. This role exists to make X the default recommendation inside those rooms. You own the agency system and the commercial architecture for Global Brands across APAC. That means holding-company and regional leadership in Singapore and India — and, as a hiring requirement, the Business Directors, Client Directors, and Account Directors who write the plans and clear the buys. A C-suite network without working-level relationships is not sufficient for this role. You will structure commercial deals, navigate complex agency structures, and create the conditions for the sales tea to win more spend. This is a senior individual-contributor role. You will operate independently, set your own map, and be accountable for agency-sourced revenue influence and partnership quality. You will work as a peer with the Global Brand sales team — close partnership, distinct ownership. This role reports to the Head of Global Brands, APAC. RESPONSIBILITIES: Build and run the agency development plan for Global Brands across APAC — covering holding companies, regional hubs in Singapore and India, operating companies, and key independents. Develop strategic relationships at two levels, b

This is a hunter role. You will own a portfolio of global brand advertisers across APAC — winning new spend, reactivating lapsed or dormant accounts, and expanding existing partnerships. You are the commercial owner for your book of business: strategy, relationships, pipeline, and revenue. You will work as a trusted advisor to brand marketers and their agency partners, building consultative, insight-led programs that put X at the center of both brand and performance plans. You will work as a peer with the Agency Development and X Cross Functional Teams — close partnership, distinct ownership. This role reports to the Head of Global Brands, APAC. RESPONSIBILITIES: Own and grow revenue across an assigned Global Brands portfolio in APAC. Hit and exceed quarterly and annual targets through new business, expansion, renewals, and reactivation. Hunt. Build a disciplined pipeline of net-new and returning advertisers.

At Vanta, our mission is to help businesses earn and prove trust. We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it. You will build the layer that makes Vanta's data actually useful: a single interpretive layer that reads across every source of truth and makes them queryable, reasoned-over, and genuinely illuminating — for EPD, for GTM, and for anyone in the org trying to understand what's happening and why. The EPD Systems team is building the infrastructure Vanta's engineering, product, and design organization depends on to understand itself. We're constructing three interlocking layers: sources of truth at the foundation, an operating system that makes delivery legible, and the intelligence layer that reasons across all of it. This role owns the intelligence layer — the one that doesn't exist yet. This is a builder role. You will ship working things yourself — prototypes, internal tools, agent workflows. You will not hand specs to someone else and wait. Communication isn't a separate deliverable; it's how you learn what to build. What you’ll do as a Senior Product Builder at Vanta: Build the intelligence layer: a cross-source interpretive layer that reads across Vanta's sources of truth and makes them queryable and reasoned-over by EPD leadership, GTM, and beyond Define what to build: scope the problem yourself, make explicit tradeoffs about what to defer, and own the sequence of what gets built and when Ship working things yourself: prototypes, internal tools, agent workflows — using AI as part of how you work, not what you report on Understand the organization: go to the teams whose decisions this layer will serve — GTM, G&A, EPD — and come back knowing what they can't answer today Catch and address AI-specific quality problems — rel

This is an ideal role for someone who can move across unfamiliar topics, reason from first principles, and turn ambiguity into practical model behavior. You will work closely with research, engineering, product, preparedness, and operations teams to build policies that are technically grounded, measurable, and responsive to real-world risk. In this role, you will: Design and maintain model policies across safety-relevant domains, including dual-use, agentic, and emerging frontier-risk areas. Translate risk and harm models into clear behavioral specifications, evaluation criteria, grading guidance, and system-level safeguards. Define practical boundaries between beneficial uses of AI and assistance that could materially enable harm, exploitation, misuse, or unsafe outcomes. Build policy artifacts that support model training, evaluation, and deplo
