Youll own native connectivity for US financial institutions: the AI-driven tooling that builds and maintains connectors, and the shared engine underneath it, including the headless server, proxy, fingerprinting and cache. We are building our US engineering hubs in San Francisco and New York, starting with a small group of staff engineers who will take technical ownership of our most critical systems.

You'd be one of the first dedicated owners of this space at Beast Industries, with the scope to define how we think about trust, abuse, and integrity across media, fintech, and creator products that reach an enormous, highly engaged audience — and the latitude to build the team and systems from a position of real technical ownership.   . You'll be the threat-modeling and systems-design owner for device attestation, account integrity, and server-authoritative detection/enforcement against bad actors — fraud rings, bot farms, credential stuffing, and abuse at scale.

Full Stack Engineer

Your surface area spans every product squad and every partnership: Mobile Security: iOS and Android app security — secure storage, certificate/key pinning, jailbreak/root and tamper detection, secure IPC, mobile authN/authZ flows, and hardening of the mobile SDK and build/release pipeline. Offensive Testing: A pen testing program you own end-to-end — internal red-team exercises (including mobile-specific testing: static/dynamic analysis, reverse engineering, API abuse), coordinated external engagements, and continuous validation against real attacker behavior.

Staff Mobile & Product Security Engineer

You will play a key role in turning prototypes into reliable, manufacturable products, working hands-on with early designs and suppliers to ensure quality and scalability. This role is ideal for an engineer excited about working across the full product lifecycle — from whiteboard sketches and 3D CAD to testing, validation, and manufacturing handoff.

Not just CAD, and not just a phase of the product lifecycle, but the whole thing: sitting with our industrial designers to figure out what the product should be, defining the requirements it has to meet, taking those requirements into architecture and detailed design, prototyping and iterating, and then following the design all the way through DFM, tooling, first article, and production ramp. Design the test fixtures, assembly aids, and inspection tooling that your subsystem needs to be built and validated at rate, while partnering closely with our test engineering team on life-test rigs and end-of-line testers.

Software Engineer - Infrastructure

Automation & enablement Automate the parts of corporate security that don't need a human — device provisioning, access reviews, vendor security questionnaires — so the team scales with headcount instead of straining against it. Endpoint & device lifecycle Write and ship device policy as code — configuration profiles, remediation scripts, and enforcement rules across macOS and Windows — with staged rollout and rollback built in from day one.

Software Engineer, Hardware Health

Real-time software you write or review runs reliably on bare-metal embedded devices and Linux-based devices alike, and you're comfortable installing, wiring, and debugging that hardware in vehicles and HITL rigs when it breaks. As a Staff Software Engineer, you'll own the architecture and design of large parts of this system: turning high-level goals into solid designs, clean APIs, real test plans, and realistic schedules, then executing with minimal oversight.
