Senior Jobs in Web3

KAST is a fast-growing force in the financial technology and startup landscape. We’re building the future of financial services with speed, precision, and world-class execution. Our culture thrives on unblocking teams, scaling fast, and building systems that match our ambition.

We’re assembling a design team built for velocity—pragmatic thinkers with strong taste, sharp instincts, and a bias for action. You don’t need Web3, crypto, or startup experience, but you do need to love building structure out of chaos. If inefficiency frustrates you and systems excite you, you’ll feel right at home.

We’re looking for a cornerstone player to elevate our cross-functional workflow and drive operational excellence across design, product, and engineering.

This role sits at the center of the product engine—part design, part systems architect, and part operations. You’ll own the infrastructure that powers KAST’s design output: design systems, workflow tooling, documentation, component libraries, process alignment, and the connective tissue between product, engineering, and design.

If you thrive in the “how we work,” not just “what we ship,” this is the perfect role. You’ll accelerate delivery, elevate quality, and create the operational backbone our team scales on.

You’re a builder, a simplifier, and a dot-connector. Strong taste, obsessive structure, and high ownership required.

Design Systems: Own, scale, and maintain KAST’s design system—components, tokens, patterns, and guidelines.

Cross-Functional Alignment: Act as the connective bridge across Product, Engineering, and Design to ensure clarity and consistent delivery.

Tools & Workflow Architecture: Manage and optimize our design tooling stack, workflows, and handoff processes for maximum velocity.

‍Documentation & Governance: Create and maintain clear documentation, standards, and governance models that keep quality high and teams aligned.

Delivery Acceleration: Remove friction in the design-to-engineering pipeline so teams can ship faster with confidence and consistency.

Quality & Consistency: Implement processes and review systems that uphold design quality across all surfaces and platforms.

Component & Pattern Development: Partner with designers and engineers to define, standardize, and evolve reusable components and product patterns.

Process Optimization: Continuously identify operational bottlenecks, propose improvements, and roll out scalable processes across teams.
