We're hiring a Senior Software Engineer to join Recast's Apps & API team: the engineers who own the customer-facing surface of our marketing mix modeling platform. That includes our flagship MMM application, agentic apps, public APIs, and MCP server. You’re a strong Python engineer who can hold their own in Ruby, navigate a Rails codebase, review PRs, and ship a fix when needed.
- Help take our MCP server from early-stage to production-grade: design decisions, implementation, and all the rough edges in between
- Contribute to our public APIs: clarity, consistency, and best practices matter more than ever as our users are increasingly building AI-powered workflows
- Build backends for agentic apps: the patterns for this greenfield work are still being defined and you'll have a strong voice in how we build
- Work closely with the EM and your teammates to shape how this team builds: you’ll have real opportunity to help define what good looks like here, not just execute against it
- Strong Python engineer: you write idiomatic Python, design and ship production APIs in it, and it's your natural default
- Comfortable enough in Ruby (Rails) to navigate the codebase, give useful PR reviews, and contribute without needing to be carried
- Designing and shipping APIs with real external consumers: developer experience, versioning, and reliability are priorities for you
- Shipping in an environment where "good enough to learn from" is a real engineering value, not a compromise
- Hands-on experience with MCP and agentic AI patterns: you've built real tools, integrations, or apps in this space
- Building with emerging tech like MCP and agentic AI: you’re willing to make opinionated architectural bets in a landscape that is continually evolving
- Working on customer-facing products with technical users: your users are developers, marketing analysts and data scientists who will notice when something isn’t right
- Startup pace is real: things move fast, not everything is written down, and priorities shift - you know how to make progress anyway
- Being part of a remote, async-first team spread across time zones where clear written communication is essential
- Python & Ruby on Rails
- REST APIs & MCP
- AWS Cloud Services & Heroku
- Bedrock AgentCore, Anthropic SDK, LangChain/LangGraph
- PostgreSQL & Redis
- Docker, Terraform, Kubernetes, GitHub Actions
Hiring Process:
- Hiring Screen - discuss Recast, your background, and questions you have
- Hiring Manager Interview - casual, mutual-fit conversation with our Head of Engineering
- Technical Interview - includes a short take-home assignment; the interview covers your approach and a code walkthrough with Q&A
- Team Interview - meet a couple of your future teammates and get a feel for how we work
- Final Interview - meet with Recast's CEO to talk about Recast and your goals
What we offer you:
- Work wherever you’re happiest. We're fully remote
- Competitive remote salary along with early-stage equity
- Highly skilled coworkers you can learn from and who are eager to learn from you
- An async-first culture with a focus on documentation over standing meetings
- Autonomy and support to do your best work in your own time
- Your local holidays plus unmetered PTO (minimum 2 weeks mandatory PTO!)
Note: Recast is committed to building a diverse team so if you are from an under-represented background in tech (e.g., women, BIPOC, etc.) please apply even if you don’t necessarily check all of the boxes here.
While Recast is officially based in the US, we're a fully remote team (one founder lives in Brooklyn, the other in Mexico City and team members in 6+ countries around the world). We can't sponsor visas at this time, however we are happy to have you join remotely from wherever you are.
If this sounds interesting to you, we'd love to learn more about you!
US-based salary range: $140,000 - $190,000
Please note salary ranges are estimated for US-based employees. Candidates from other geographies may have the salary range adjusted based on their local markets.

What We Do
Recast is building the world’s most rigorous MMM platform. Here's how we're different: 1. We take accuracy (really) seriously. From configuration, to stability checks, to parameter recovery exercises, to ongoing backtests – the Recast process holds every model to an incredibly high performance standard before and after delivery. 2. We don’t hide anything. At Recast, we turn the black box into a glass box. We show uncertainty for all point estimates, send weekly model accuracy scorecards and publish all model docs openly. It helps our clients build trust in their models and hold us accountable as their vendor. 3. We’re obsessed with model quality. More than 30% of the Recast team holds a PhD in math or statistics. Our research into upper & lower funnel channel interaction, time-varying ROIs, spike modeling, and more, continues to improve Recast's proprietary media mix model.
