What are the responsibilities and job description for the Senior Software Engineer position at The Starr Conspiracy | TSC?
Location: Northampton, MA (Hybrid)
This position requires working onsite at our Northampton office 2–3 days per week. Candidates should live within a reasonable commuting distance or be willing to relocate.
About the role
You’ll be joining our Northampton MA-based development team, using the latest AI coding tools to build GTM products that connect our clients to their customers. As the technical delivery lead, you'll help set a culture where speed and quality go together: we move fast with agentic tools and hold a high bar on everything we ship. You'll take ambiguous problems and turn them into clear plans, working across product features, custom work for our clients, internal tooling, and the infrastructure underneath. On a small team, you'll have real say in what we build and how.
What you'll do
- Use agentic coding tools to move quickly and review their output critically
- Be the technical leader for product delivery
- Build and ship features for our core products
- Collaborate with our sales team to build custom features for customers
- Improve our development processes and tooling, including our agentic coding setup and ops environment
- Mentor junior members of the team
- Keep up to date with what’s new in AI and bring interesting ideas to the team
Required Qualifications
- 5 years of professional software development experience; a Bachelor's degree in CS, Data Science, or a related field is preferred
- Strong in Python or TypeScript
- Regular use of at least one of Claude Code, Codex, or Cursor, and the ability to critically analyze their output
- Excellent problem-solving/critical thinking skills and attention to detail
- Ability to work and communicate collaboratively in a remote team environment
- You'd rather work at a small company, with less process and more say in what gets built
Nice to have
- MongoDB, FastAPI, Vercel, Railway, Clerk
- Familiarity with marketing and GTM
About The Starr Conspiracy
The Starr Conspiracy is the B2B marketing agency where fundamentals meet AI transformation. We are senior by default, AI-native in how we operate, and we don't sell AI experiments. We build marketing systems that actually work.
We blend proprietary AI systems we built ourselves with the strategic marketing skills we have honed over 25 years. The AI accelerates insight, execution, and scale. Our strategists supply the judgment: what to build, what the output means, and what executives do about it.
We reject the false choice between fundamentals and innovation. We master both, and we tell clients what they need to hear, not what they want to hear.
