About Infilla

Infilla is on a mission to make housing happen faster

The US is in a housing crisis with 4M to 7M missing housing units, which contributes to homelessness and income inequality. However, regulating $2.1T of annual construction for housing is challenging and it can take years to get the necessary permits to even start construction (it takes a median of 620 days for a housing-related project in San Francisco to get approval). Local governments are still using a mix of paper, excel sheets, email, and legacy 90’s software to manage their workflows and are frustrated by the current options.

Infilla supports those agencies with user-friendly permitting portals, modern review workflows, and a suite of tools for government staff and applicants. Our work is based on 1000+ hours of user research with 250+ staff and applicants in 50+ jurisdictions.

Infilla recently raised a $5M seed round and is backed by Basis Set Ventures, Base10 Partners, the Urban Innovation Fund, SHAKTI VC, 20GROWTH, Bloomberg Beta, and 20+ founder angels.

The role

You'd be the founding engineer with a team of experienced technologists in product and engineering, building new products. There's several contracts per employee so we're capacity constrained with plenty to build.

What you’ll do

  • Solve ambiguous real-world problems with high technical autonomy

  • Collaborate with the founding team and customers to shape the product roadmap & designs

  • Find creative ways to iterate and deliver value

  • Ship to customers multiple times per week

  • Contribute to Infilla’s company culture as a founding team member

Our tech stack

We chose “boring” technologies to focus on delivering quickly for our customers:

How we work

  • We collaborate multiple times per-week in-person with work-at-home days to focus on IC work

  • We spend a lot of time with customers during site visits and calls

  • We build pragmatically and iteratively, informed by customer conversations

  • We make time to give & receive feedback that improves how we collaborate

  • We believe in writing for clarity & alignment

Our values

  • Progress > Perfection - Get it working now and make it pretty later.

  • Kind > Nice - Share clear, helpful feedback often. Voice your concerns and listen.

  • Ideas > Hierarchy - Best idea wins regardless of source. Be intellectually honest.

  • Courage > Comfort - We do the right thing, even when hard or uncomfortable.

Skills & qualifications

We'd love to hear from you if you are a serious builder who...

  • Are oriented towards mission & users over specific technology or area of the stack

  • Have 5+ years of professional experience in full-stack product development

  • Fluent, comfortable, and proficient in React

  • Are product-minded, curious, empathetic, and care about the user experience

  • Prioritize moving quickly and finding creative ways to ship early

  • Have experimented and used AI as part of your coding practices

  • Communicate clearly with both technical and non-technical stakeholders

  • Are a humble, kind team player based on the West Coast with a strong preference for the SF Bay Area

We cannot sponsor visas at this time.

Research shows women & minorities are more likely to consider themselves unqualified if they don't meet every single requirement in a job description. This represents what we're ideally looking for, but everyone is unique. We hire for strengths & potential, not lack of weakness.

Interview process

We aim to make this happen in 1-2 weeks:

  1. Initial call (30 min) - Casual chat to understand your experience and interest in Infilla

  2. Product exercise (120 min) - Write about how you'd approach a product feature

  3. React exercise (60 min) - Do a practical React coding exercise

  4. Product sense exercise (45-60 min) - Go through a product sense exercise and learn more about Infilla

  5. Paid contract work - Work on a small project together. You’ll learn what it’s like to work with us as we’re learning what it’s like to work with you. We can discuss alternatives if this doesn’t work for your situation. We do reference calls in parallel

  6. Full-time offer 🎉

We’re excited to build with you in making more housing happen faster! 🏡
