A.Team places senior backend engineers from a curated, invite-only network of builders. Describe the engagement, get a curated shortlist of two to three matched engineers within 72 hours, interview on your terms, and have a builder embedded in your team by week one. Engagements run three to twelve months, either solo or on a team with a managing partner who owns delivery. Pricing is outcome-scoped, not hourly.
What a backend engineer hired through A.Team looks like
A typical A.Team backend engineer has eight to twelve years of production experience building APIs, services, and data-heavy systems at companies past the Series B stage. The tech mix across missions includes Python/Django for REST API work, Kotlin for JVM-based services, Node.js for event-driven systems, and Go for high-throughput applications. A meaningful share of backend missions are AI-adjacent, backends that serve model inference, process large document volumes, or manage real-time data pipelines. A few involve DLT and blockchain backends (iCapital) and regulated financial services infrastructure (Drawbridge).
Most backend missions are solo placements into existing engineering teams, a senior backend engineer owning an API surface or a service integration. A handful involve small backend teams (two to three engineers) for API-heavy builds (Descope, Wolt Fintech) where the backend is the critical path.
A recent example: Sandow, a media and research company with decades of consumer intelligence, brought in Richard Abrich, a Principal AI Engineer whose background spans enterprise AI builds at Microsoft and healthcare institutions. Sandow needed to unify 150+ proprietary data sources into a real-time intelligence platform that let business leaders query complex consumer research in natural language. Abrich built a PostgreSQL-based data platform with dynamic SQL generation, a FastAPI backend serving the query interface, and OpenAI GPT model integration for natural language understanding, all deployed via Docker on AWS. The result: time-to-insight dropped from weeks of manual analysis to real-time response, and Sandow launched a live query platform that gave beauty brand clients direct access to their most complex consumer data. Richard Abrich described the impact: "Business leaders can have conversations with their most complex data and get trustworthy, quantitative answers back in seconds, not weeks."
Why the quality is there
A.Team's builder network is invite-only, with admission running about two percent of applicants. Backend engineers enter the network through delivery history in production backend systems, not credentials or self-reported expertise. The backend missions in A.Team's pipeline reflect real production constraints: regulated fintech (iCapital's DLT backend, Drawbridge's senior backend work), developer tools (Descope's API builders), and AI-backend crossover (Velon's AI/backend hybrid). The filter is for engineers who've shipped in those environments before.

Why A.Team for a backend engineer specifically
Senior-only bar, verified by delivery.
Every backend builder in the network has shipped production backend systems at comparable companies. The evaluation is delivery history, not algorithm interviews. For a CTO who's seen too many "senior" contractors who can answer leetcode questions but can't design a reliable API under real-world constraints, the difference matters.
Backend-to-AI crossover coverage.
A meaningful share of backend missions are AI-adjacent, backends that serve model inference or process large data volumes alongside AI layers. A.Team's network includes backend engineers with AI integration experience alongside pure backend specialists.
Scales to a small API team.
If the backend scope grows past one engineer, A.Team can add backend specialists in one engagement without restarting procurement. The managing partner coordinates team delivery.
How the engagement works
Intake.
Describe the engagement at a.team/get-started or in a 45-minute scoping call with a partner. You leave with a shared picture of the backend scope and the team shape that fits.
Shortlist.
Within 72 hours for single-builder engagements, or three to five business days for team engagements, A.Team returns two to three named engineers with their background, past missions, and the specific backend systems they've built.
Kickoff.
Week one includes setup on your systems, a working session on the first two weeks of milestones, and alignment on API design conventions and data architecture.
Managed delivery.
The managing partner runs weekly delivery reviews. The backend engineer ships against the scoped service or API surface. Team shape adjusts if the backend scope grows.
Common role variations
Most backend missions fall into three shapes. Senior backend engineer (7+ years) is the default: Python, Node, Go, or Kotlin production experience, REST/GraphQL API design, database ownership, and service integration. API specialist applies when the engagement is primarily API platform work, building a developer-facing API product, managing versioning and documentation, or extending an existing API surface for a new integration. AI-backend engineer applies when the backend role includes serving model inference, managing embedding pipelines, or building the data infrastructure that feeds an AI system.
The full scoping playbook is in the backend engineer hiring guide.
What it costs
Senior backend engineering engagements through A.Team are outcome-scoped rather than hourly. Rate benchmarks by stack and specialization are in the backend engineer rate guide, and an intake at a.team/get-started returns a shortlist and a scoped proposal.

Common questions
The typical backend builder placed on a mission has eight to twelve years of production experience, including a track record of owning a service or API surface in production. Contributing to one is below the bar. The senior bar is for engineers who've designed APIs, managed production incidents, and made architecture decisions. Implementing tickets is also below the bar.
Two to three matched backend engineers land on your desk within 72 hours of an intake submission at a.team/get-started. Standard Python/Django or Node.js engagements land fastest; specialized stacks (Kotlin, Go, DLT/blockchain) and AI-backend crossover roles run three to five business days.
A.Team places backend engineers with AI integration experience as part of the network. The intake brief should specify the AI layer (inference serving, embedding pipelines, LLM API integration) so the matching returns engineers with relevant production history. Backend-to-AI crossover is a common shape in A.Team's mission set.
Every engagement includes a trial period at the front end. If the match needs to shift, the managing partner reshapes the team without restarting the commercial.
If 80 percent or more of the scope is server-side, API design, database ownership, service integration, hire a backend engineer. If the scope regularly crosses into the frontend (writing React components, owning the UI as well as the API), hire a fullstack engineer. The boundary is worth clarifying at intake.
People also ask
US-based senior backend contractors typically run $130 to $200 per hour depending on specialization. Go and Kotlin specialists and AI-backend engineers are at the higher end of that range. Full benchmarks are in the backend engineer rate guide.
An FTE backend search takes 60 to 90 days. A contractor through a curated platform takes one to three weeks. A.Team's intake-to-working-builder timeline typically runs 72 hours for single-engineer engagements and up to two weeks for team builds.
A.Team's backend missions span Python/Django, Node.js, Kotlin, Go, and Elixir. Python and Node are the highest-volume matches; Go, Kotlin, and Elixir engagements exist in the mission set. The intake brief specifies the stack and A.Team matches on production history in that runtime.
A backend engineer owns API layers, service logic, and application databases. A data engineer owns data pipelines, warehouse schemas, and the infrastructure that moves data between systems. If the primary scope is building and maintaining APIs, hire a backend engineer. If the primary scope is ETL pipelines, data warehouse management, or real-time data streaming, hire a data engineer.
