SiFive’s unrivaled compute platforms are continuing to enable leading technology companies around the world to innovate, optimize and deliver the most advanced solutions of tomorrow across every market segment of chip design, including artificial intelligence, machine learning, automotive, data center, mobile, and consumer. With SiFive, the future of RISC-V has no limits.\nAt SiFive, we are always excited to connect with talented individuals, who are just as passionate about driving innovation and changing the world as we are.\nOur constant innovation and ongoing success is down to our amazing teams of incredibly talented people, who collaborate and support each other to come up with truly groundbreaking ideas and solutions. Solutions that will have a huge impact on people's lives; making the world a better place, one processor at a time.\nAre you ready?\nTo learn more about SiFive’s phenomenal success and to see why we have won theGSA’s prestigious Most Respected Private Company Award(for the fourth time!), check out ourwebsite andGlassdoor pages.\nJob Description:\nAbout the Role -\nAs a Staff Physical Design Engineer (High-Speed Interconnects), you will be responsible for the end-to-end implementation of high-bandwidth Network-on-Chip (NoC) and Uncore subsystems.\nThis is not a traditional \"siloed\" backend role; you will operate at the intersection of architecture, design and physical implementation. You will drive PPA (Power, Performance, Area) outcomes by influencing RTL structures and floorplanning strategies early in the design cycle. Your expertise in advanced process nodes and system-level data flow will be critical in delivering scalable, high-frequency IP that forms the backbone of our next-generation compute platforms.\nResponsibilities - What You’ll Do\nEnd-to-End Implementation: Execute the full physical design flow (RTL-to-GDSII) for complex NoC and Uncore subsystems, ensuring timing closure and routability for interconnects.\n\nArchitecture & PD Co-Design: Partner with RTL and Architecture teams to perform early-stage feasibility analysis. Identify physical bottlenecks in the microarchitecture and propose RTL restructuring, such as optimized pipelining or bus-width adjustments, to meet PPA targets.\n\nAdvanced Floorplanning: Own hierarchical partitioning and macro placement. You will define the physical blueprint for massive die areas, optimizing pin assignments and global routing tracks to minimize latency across the fabric.\n\nInterconnect Problem Solving: Solve unique NoC challenges, including long-wire RC compensation, repeater strategy for global signals, and complex clock/reset distribution across hierarchies.\n\nMethodology Innovation: Develop and refine automated flows for hierarchical implementation. You will identify gaps in existing scripts and tools to improve turnaround time and design quality across multiple technology nodes.\n\nTechnical Mentorship: Provide technical guidance to mid-level engineers, leading design reviews and establishing best practices for high-performance physical implementation.\n\nRequirements - What You’ll Bring\nDeep Experience: 7+ years of hands-on physical design experience, with a proven track record of closing complex blocks or subsystems on FinFET nodes (7nm and below).\n\nSystems-Level Mindset: Understanding of NoC designs. You should be comfortable navigating RTL and understanding how logic structures translate to physical layout.\n\nHierarchical Expertise: Proven ability to manage top-level integration, including budget constraints, hierarchical P&R and timing closure.\n\nTool Mastery: Expert-level proficiency with industry-standard EDA suites - Synopsys and/or Cadence implementation and sign-off tools.\n\nAnalytical Rigor: A data-driven approach to PPA tradeoff optimization; accompanied by a detail-oriented mindset and clear communication.\n\nEducation: BS or MS in Electrical Engineering, Computer Engineering, or a related field.\n\nWhy Join Us?\nBe part of the RISC-V movement and help define the future of computing architecture.\n\nWork on industry-leading IP adopted by top customers and shipped in high volumes worldwide.\n\nCollaborate with world-class engineers in a supportive, fast-paced, learning environment.\n\nEnjoy a culture that values innovation, ownership, and technical excellence.\n\nOur large IP portfolio offers opportunities to engineer solutions across multiple IPs and product families over time.\n\n Additional Information:\nThis position requires a successful background and reference checks and satisfactory proof of your right to work in:\nIndiaAny offer of employment for this position is also contingent on the Company verifying that you are a authorized for access to export-controlled technology under applicable export control laws or, if you are not already authorized, our ability to successfully obtain any necessary export license(s) or other approvals.\nSiFive is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.","description_format":"text","description_chars":5249,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Processors, MCUs & AI Chips","Semiconductor IP & Chip Design Services"],"lifecycle":[{"event":"open","at":"2026-10-09T14:54:49Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":18,"expected_fill_days":72,"reasons":["conf:2","velocity","win:early","comp:brand"],"computed_at":"2026-10-28T05:59:10Z"},"pay":null,"html_url":"https://alion.io/job/sifive-staff-engineer-physical-design-high-speed-interconnects","json_url":"https://alion.io/job/sifive-staff-engineer-physical-design-high-speed-interconnects.json","meta":{"generated_at":"2026-10-29T00:42:16Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":982,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":58802},"rest":"https://alion.io/mcp/rest/get_company?id=58802"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsifive-staff-engineer-physical-design-high-speed-interconnects"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fsifive-staff-engineer-physical-design-high-speed-interconnects"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fsifive-staff-engineer-physical-design-high-speed-interconnects"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/sifive-staff-engineer-physical-design-high-speed-interconnects\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsifive-staff-engineer-physical-design-high-speed-interconnects"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":2180768}},{"tool":"search_jobs","arguments":{"company":"sifive.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":2180768},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
