Who we are at Osmo:

Osmo is a digital olfaction company on a mission to give computers a sense of smell to improve the health and wellbeing of human life. Why Our sense of smell both enriches and saves lives and has a deep and direct connection to our emotions and memory.

Were headquartered in Elizabeth NJ with an additional office in Somerville MA. We provide complimentary shuttle service from Brooklyn and Newark NJ.

Osmos engineering team is currently junior and were looking for the senior backend voice to help it grow up. This is a backend-forward seat with a data component on the side not a database architecture role: youll own systems up through the API layer bringing production judgment on-call experience and structured problem solving the team doesnt have yet.

Youll have the trust to question whether a big ambiguous problem is even worth solving and the autonomy to scope the right first chunk of it rather than diving straight into code. This isnt a scale or performance role at this stage. Its about laying a robust foundation handling long-running requests and calls to systems that can fail and building real recovery paths not just happy-path code.

• Own Backend Systems Through the API Layer Handle the complexity underneath the API contract not just define it.

• Bring Production Judgment Take on monitoring and on-call responsibility knowing what should be watched and why.

• Build for Failure Not Just the Happy Path Handle long-running requests and calls to other systems that might fail or crash with real recovery paths.

• Lay the Foundation for Scale Later Focus on robustness and foundational reliability now not premature scale or performance optimization.

• Work With Data the Way a Backend Engineer Does User-oriented data work not database architecture.

• Be the Senior Backend Voice Bring structured problem solving and production experience to a team that doesnt have it yet.

• 6-15 Years of Non-Internship Experience Staff-level backend engineer; internships co-ops and student roles dont count toward this.

• A Designer Not Just an Implementer Real system or workflow design ownership not just built X shipped Y without design-level involvement.

• Real Production Ownership Has run services in production including on-call and monitoring responsibility.

• Staff-Level Problem Solver Can take a large ambiguous problem question whether its the right one to solve at all and scope a sensible first chunk instead of diving straight in.

• Comfortable Building the Foundation Not chasing scale for its own sake; ready to do foundational reliability and robustness work first.

• Python and SQL baseline expected; TypeScript Go or Scala experience is a plus not a requirement.

• NYC/NJ based.

• Mentorship Mindset Experience leveling up a team valuable given how junior Osmos engineering team is today.

• Full-Stack Exposure React/TypeScript experience even though this isnt a full-stack role.

• Broader Systems Experience Go or Scala exposure as a signal of real distributed-systems depth.
