Note: The job is a remote job and is open to candidates in USA. ActiveProspect is on a mission to make consent-based marketing the best channel for online customer acquisition. The Senior Software Engineer (Elixir) will own customer and business outcomes, working closely with teams to design, ship, and iterate on solutions while mentoring others and ensuring high-quality technical decisions are made.

Responsibilities

• Own outcomes end-to-end, wherever you're deployed. Frame the problem, design it, ship it, own the metric. Descope to the cheapest version that works. Prototype in days
• Stay close to customers. Shadow sales and support, join advisory conversations, and let customer reality drive technical decisions. Propose what to build, defer, and kill
• Own your domain and share it. Its interfaces, reliability, performance, and security, including on-call for the systems you own. Consent and PII handling are central to customer trust. Bring patterns, tooling, and hard-won context back to the wider org rather than hoarding them
• Architect AI-driven leverage. Build AI-assisted workflows that hold up, evolve the team's practices as tooling changes, and look for product wins AI unlocks (smarter routing, anomaly detection, and more)
• Multiply the teams you touch. Mentor on judgment and product sense, not just syntax. Write decision memos and ADRs. Enable Product and Design to self-serve

Skills

• A track record of shipping something end-to-end that you cared about and owning the outcome, not just the code
• Product judgment: pushing back on a bad spec, proposing the cheapest experiment, and descoping well
• Comfort embedding with unfamiliar teams and codebases, getting productive fast, and leaving them better than you found them
• Deep full-stack expertise: Elixir, Vue 3 / Nuxt, Postgres at scale, AWS (Kubernetes a plus). Node.js a bonus
• Strong systems design judgment in ambiguous contexts, and a security mindset aligned with sensitive consumer data and compliance
• Fluency reading AI output critically and building your own AI-assisted workflows
• Clear written and verbal communication. Mentorship experience. 5-10% travel
