• You think in systems, you ship production code, and you care deeply about what actually makes it into the hands of users. • You'll work alongside a design engineer already on the team, and together you'll own the bridge between design intent and shipped experience across our core product. • You'll build and evolve the design system in code, raise the quality bar for UI that ships, and create the tooling and workflows that help the entire design and engineering org move faster. • You'll own the integrity of the design system across both surfaces. • You'll be the person who cares about the last 10%: transitions, micro-interactions, responsive behavior, loading states, edge case UI, accessibility. • You'll look at how the design and engineering teams collaborate, prototype, and ship, and you'll build tools and processes that make it better. • You're capable of shipping production-ready code. Whether that's components in the design system, UI improvements in the product, or internal tooling, the work you do is built to the standard of something that goes in front of users. • You'll partner closely with product designers, but the collaboration model isn't a handoff. Designers own the problem space, user insight, and experience strategy. You own making that strategy real at the highest level of craft. • You'll also work directly with frontend and full-stack engineers. You'll establish patterns and components they can build on, review UI implementations, and raise the standard for what 'done' looks like in the codebase.

**What you'll do** You're a design engineer in the making — someone drawn to the place where how things look meets how they work. You like designing interfaces, and you like coding them too. You care whether a button feels right, not just whether it works. You'll help design and implement features end-to-end, with guidance from the team. You'll move fast — we mean it — using AI-powered dev tools (Cursor, Claude Code, etc.) to punch above your weight and ship at a pace that wouldn't otherwise be possible. You'll contribute to the frontend experience: layout, interaction, motion, polish. You'll work directly with engineering and product, iterate in hours instead of weeks, and communicate plainly. No corporate padding. **Extra pluses** Experience playing with Figma or similar design tools for prototyping. You care about accessibility. You read fiction, build worlds, or make things for fun.

Role Description As a Senior ASIC Design Engineer, you will take a leadership role in defining, implementing, and delivering critical IP blocks and subsystems for Positron.ai’s inference ASICs/SoCs. You will own the microarchitecture from high-level concept through RTL signoff, collaborating across architecture, verification, and physical design to achieve ambitious PPA and schedule goals. In addition to hands-on SystemVerilog design, you will mentor junior engineers, influence methodology, and drive key architectural tradeoffs that impact silicon performance and efficiency. Key Responsibilities - Microarchitecture & RTL Leadership: - Define and document microarchitecture for complex IP blocks/subsystems. - Deliver production-quality, parameterized SystemVerilog RTL with well-defined interfaces, power/clock intent, and embedded assertions. - Technical Ownership & Signoff: - Lead lint, CDC/RDC, DFT integration, and synthesis bring-up; collaborate with PD on floorplan and timing closure. - Own PPA metrics for assigned blocks and drive microarchitectural optimizations to meet targets. - Advanced Interface & Memory Integration: - Architect and integrate high-performance interconnects (AXI/CHI/ACE), DMA engines, coherency logic, and high-speed memory interfaces (HBM/DDR). - Engage with IP vendors and internal stakeholders to ensure seamless integration. - Methodology & Best Practices: - Develop and enforce coding guidelines, reusable IP packaging, and signoff checklists. - Contribute automation flows (Python/Tcl/Make/CI) to improve team efficiency. - Cross-Functional Collaboration: - Partner closely with Verification to define test plans and reference models. - Work with Architecture and Performance teams to correlate models against RTL. - Support bring-up, post-silicon debug, and customer engagements as required. - Mentorship & Technical Leadership: - Guide junior engineers in design techniques, methodology, and problem-solving. - Lead design reviews, drive consensus on tradeoffs, and advocate for best-in-class solutions. Qualifications - BS/MS in EE/CE (or related) with 8+ years of ASIC/SoC RTL design experience on complex, high-performance silicon. - Proven track record of leading designs from spec → microarchitecture → RTL → signoff with strong PPA outcomes. - Deep SystemVerilog RTL expertise, including clocking, resets, CDC/RDC handling, and protocol correctness. - Extensive experience with front-end flows/tools (lint, CDC, synthesis/STA, DFT) using major EDA suites. - Hands-on expertise with at least three of: HBM/DDR, PCIe/CXL, AMBA AXI/ACE/CHI, cache/memory hierarchies, high-throughput datapaths. - Strong cross-functional communication skills, capable of leading technical discussions and producing clear specifications. Preferred Qualifications - Background in AI/ML accelerator design (matrix/vector engines, compression, NoC bandwidth planning). - Formal verification/SVA expertise for property checking and design assertions. - Experience with low-power design techniques (clock-/power-gating, UPF/CPF). - Collaboration experience with cocotb/UVM for checkers and reference model co-development. - Familiarity with RISC-V subsystems, coherence protocols, or customer-owned tooling (COT) flows. Benefits - Shape the next generation of AI inference hardware with a high-caliber, collaborative team. - Take technical ownership of critical silicon components that directly impact product success. - Competitive salary + equity, comprehensive benefits, and flexible work environment. - Opportunities to innovate, lead, and grow your influence in a rapidly evolving space. Compensation and Benefits The base salary range for this role is $225,000 – $350,000.
