 Software Engineer (New Grad - Construction Tech Platform)
 
 
 
 
 Company:
 
 Agave (YC W22)
 
 
 
 Location:
 
 San Francisco, CA (FiDi)
 
 
 
 Employment Type:
 
 Full-time
 
 
 
 Work Arrangement:
 
 On-site 5 days a week
 
 
 
 About The Role
 
 
 
 Our client is a well-funded, profitable YC-backed startup (YC W22) modernizing the
 
 $12 trillion global construction industry
 
 . They solve a massive problem: connecting fragmented, siloed software systems&mdash;many of which are 20-40 years old, on-prem, and lack modern APIs. They build proprietary APIs to connect these systems and wrap them in a modern UI to automate critical work, like syncing financial data between job sites and accounting offices. The company has over
 
 200 paying customers
 
 , is
 
 cash-flow positive
 
 , and is backed by investors like
 
 Accel
 
 and leaders from Procore and Autodesk.
 
 
 They are seeking a
 
 world-class New Grad Software Engineer
 
 who loves
 
 simplifying complex systems, unifying fragmented data, and building high-scale backend systems
 
 . This role offers high ownership and the chance to work on unique technical challenges that exist at the intersection of old-school enterprise and modern cloud infrastructure.
 
 
 
 What You'll Be Doing (Interesting Technical Challenges)
 
 
 
 Your core work will be split between backend and full-stack development, with a focus on core infrastructure:
 
 
 <ul>
 <li>
 Unification: Unifying dozens to hundreds of fragmented, heterogeneous systems under a single, generic API standard defined by the company (covering data models, authentication, and features like filtering)
 </li>
 <li>
 On-Prem Connectivity: Connecting with many types of legacy on-prem systems (SQL-based, DLL-based, API-based) and innovating to provide secure, real-time communication and webhooks where they don't natively exist
 </li>
 <li>
 Scale &amp; Speed: Handling millions of API requests per day and building elegant caching layers to efficiently store and retrieve large amounts of data, reducing latency
 </li>
 <li>
 Operational Excellence: Creating a reliable, SLA-enforced API layer on top of old, unreliable systems ("building a skyscraper on quicksand"). This involves building creative, scalable testing frameworks to catch edge cases across 1,000+ endpoints
 </li>
 <li>
 Full-Stack Development: Building internal front-end applications (Sync, Analytics) that "dog-food" their own APIs, ensuring the APIs are world-class
 </li>
 <li>
 Variety: Each new integration presents a unique "archaeological" and engineering challenge, requiring deep research into its specific nuances
 
 
 </li>
 </ul>
 
 Requirements
 
 
 
 <ul>
 <li>
 0-1 years of experience as a backend or full-stack software engineer (New Grad level)
 </li>
 <li>
 Must be able to work independently without much guidance
 </li>
 <li>
 Loves simplifying complex systems and unifying fragmented data
 </li>
 <li>
 Must be willing to work in-person 5 days/week in San Francisco
 
 
 </li>
 </ul>
 
 Benefits
 
 
 
 <ul>
 <li>
 Salary: $130K - $240K
 </li>
 <li>
 Equity: 0.05% - 0.20%
 </li>
 <li>
 Visa Sponsorship: Available (TN, OPT, H1B Transfer) for US and CAN candidates
 </li>
 <li>
 Benefits include: 90% healthcare coverage, 401k match (up to 4%), sizable relocation bonus, on-site gym, and daily DoorDash stipend for dinner
 
 
 </li>
 </ul>
