Melius internships: choose the internship window, then prove you can ship
Melius's engineering internships reviewed on 2026-09-23 were unusually close to full-time product work. The employer listed separate Fall/Winter 2026 and Spring/Summer 2027 software-engineering internships in New York City. Both center on the same agent-native creative-product stack and expect interns to build, test, and ship alongside the engineering team. Choose the term that fits your calendar, then use the exact live posting and the current InternshipDeadlines record for availability, deadline, pay, location, eligibility, and work-authorization details.
01
Software Engineering Intern — Fall/Winter 2026
CS students who can commit to the Fall/Winter window and can point to a real shipped project, open-source contribution, or previous internship work rather than only coursework.
What the work looks like
The role covers product engineering across Melius's generative-media canvas, timeline editor, asset search, and agent/model orchestration layer. Examples include building new agent tools end to end, watching user sessions and fixing rough edges, adding evals and traces, and polishing canvas interactions. The posting says interns work directly with senior engineers and founders and are expected to take ownership comparable to a full-time engineer.
Candidate profile
The posting asks for a student pursuing a CS degree or equivalent who has built something real, can work effectively in TypeScript, and has gone beyond basic chatbot use with LLMs, tool-calling, agent frameworks, React Flow, Yjs/CRDTs, or similar systems. It does not publish a sponsorship policy or universal graduation window in the reviewed text. Do not infer either.
Location & timing
New York City, on-site. The reviewed posting is specifically for Fall/Winter 2026. Its offer section states an $8,500 monthly salary, a $2,500 monthly housing stipend, and a $70 meal per diem. Keep those terms attached to this exact posting and recheck them before publication or application.
CS students targeting a Spring/Summer 2027 engineering internship who want startup product ownership and can show shipped software plus hands-on agent/LLM experimentation.
What the work looks like
The Spring/Summer posting describes the same core engineering environment: Next.js and a real-time CRDT canvas on the frontend; NestJS, MikroORM, Postgres, Temporal, and Turbopuffer on the backend; and an agent/model orchestration layer. Intern work can include new agent tools, user-session-driven fixes, evals and traces, and product-polish work.
Candidate profile
The reviewed posting asks for a CS student or equivalent who has built something real, can become productive in TypeScript quickly, and has practical exposure to LLM, tool-calling, or agent systems. It does not establish a reviewed company-wide sponsorship rule or one universal deadline. Leave those fields to the exact current role record and employer posting.
Location & timing
New York City, on-site. The reviewed posting is specifically for Spring/Summer 2027. Its offer section states an $8,500 monthly salary, a $2,500 monthly housing stipend, and a $70 meal per diem. Recheck the exact role before relying on these terms.
Pick the term first. Fall/Winter 2026 and Spring/Summer 2027 are separate employer postings, not one evergreen internship with interchangeable dates.
Treat 'built something real' as a preparation signal. A deployed project, open-source contribution, or previous shipped internship work fits the employer's stated bar better than a generic list of classes.
Prepare around the actual stack and work. TypeScript, agent and tool-calling systems, React Flow or CRDT-style collaboration work, evals, traces, and product iteration are directly relevant to the reviewed postings.
Keep compensation attached to the exact requisition. Do not convert the salary, housing stipend, and meal per diem into one invented salary or company-wide package.
Do not infer a deadline, sponsorship policy, remote option, or universal graduation window. The reviewed postings do not establish them.
Before applying, use the current InternshipDeadlines listing and then the employer posting to confirm the role remains available and its terms have not changed.
Reviewed September 23, 2026. The two Melius Ashby internship postings were rechecked September 23, 2026. They support the term split, New York City on-site setting, engineering work, candidate-preparation signals, stack, and posting-specific compensation described here. Ashby's summary displays $11,000 monthly compensation, while the offer section separates $8,500 monthly salary, $2,500 monthly housing stipend, and $70 meal per diem; this snapshot preserves those components rather than relabeling the summary as salary. The postings do not establish one company-wide application deadline, sponsorship policy, graduation window, or permanent internship calendar. Check the current InternshipDeadlines role record and employer posting before applying because availability and role-level details can change.
