Job Details

80Twenty is a boutique marketing recruitment agency that connects high-growth companies with exceptional candidates.

Want to build technology that truly moves the needle in healthcare? Join a fast-scaling, profitable healthcare services company — independently grown and not VC-backed — on a mission to make healthcare simpler, smarter, and more human! Our client is a healthcare tech and services company based in San Francisco, combining clinical expertise, operational excellence, and modern engineering to reshape how people experience care. From personalized medication management and transparent pharmacy pricing to community-based chronic care support, we're building a system that empowers both patients and providers.

This is a fully onsite role based in San Francisco, CA. Candidates must be located within 30 miles of San Francisco. The standard schedule is Monday-Friday, 9am-7pm and may vary depending on business needs and role responsibilities.

What the role looks like

As a Staff Software Engineer, you'll help accelerate our product's reach and retention by building the systems that power acquisition, activation, and monetization. Working cross-functionally with engineering, product, design and data, you'll own high-leverage projects that directly shift growth metrics.

In this role you will:

• Architect and deliver features spanning frontend, backend, and data infrastructure to drive conversion, engagement, and retention.
• Build and refine reliable event pipelines, identity frameworks, and attribution systems that power data-driven growth decisions.
• Collaborate with design to rapidly prototype and iterate high-performance landing experiences and lean tools for capturing user intent.
• Partner with product and data teams to isolate key growth hypotheses, test them quickly, and translate results into actionable learnings.
• Bring full-stack fluency (frontend and backend) along with a strong product mindset—being comfortable with ambiguity and shipping high-quality work at pace.

You might be a great fit if you

• Have 5+ years of delivering production web software with measurable business impact.
• Are comfortable working across the stack: backend APIs and infra (auth, cookies, HTTP/CDN) and enough frontend to iterate user-facing flows.
• Have owned event instrumentation end-to-end (schema design, tag management, server-side forwarding).
• Understand SEO fundamentals (Core Web Vitals, crawlability, structured data).
• Are fluent in SQL and Python.
• Have strong product instincts: you can turn vague growth ideas into minimal, testable launches and iterate fast.
• Are familiar with GTM tools, ad pixels, and analytics frameworks for growth work.

Nice-to-haves

• Mobile growth experience—deep linking, install attribution, web ↔ app journeys.
• Experimentation design expertise—know how to set up sound A/B tests, understand power and sequential testing risks.
• Exposure to multi-touch attribution or MMM frameworks and ability to automate campaign hygiene/data QA.

Why join us?

• Top-of-market compensation plus meaningful equity—your effort helps shape the company.
• Join a team of high-caliber, mission-driven engineers, designers, and operations leaders who value humility, excellence and empathy.
• Be part of a profitably growing company—not VC-backed—which gives you more direct influence on outcome and culture.
• A vibrant office in downtown San Francisco (just steps from BART/Muni) built for in-person collaboration and energetic teamwork.
• Rich benefits including comprehensive medical/dental/vision, 401(k) match, unlimited PTO, wellness perks, and a subscription to experience the same care our patients do.

If you're excited to apply your engineering expertise to meaningful healthcare infrastructure — and want to join a company that values autonomy, sustainability, and impact — we want to hear from you!

Base salary: $250k-300k DOE + generous equity and benefits
