Find the best platforms to hire AI engineers in October 2026. Compare Upwork, Toptal, Arc.dev, Lemon.io, Turing, LinkedIn, Teamvoy, and Clera side by side.
Finding the best platforms to hire AI engineers is harder than it looks. Most job boards are flooded with generalists; AI talent is scarce and expensive. Best overall: Toptal. Best for startups on a budget: Upwork. Best for VC-backed companies wanting warm intros: Clera. Read on for the full breakdown.
Key takeaways
- Vetted platforms like Toptal and Turing screen candidates before you see them, which cuts your review time but raises the hourly rate to $100–$250/hr.
- Open marketplaces like Upwork let you post for free and receive bids within hours, but you own all the screening work yourself.
- Arc.dev sits between the two extremes: pre-screened AI engineers at $60–$150/hr, with both freelance and full-time remote options.
- Clera's own data shows 95 companies currently have at least one open role on the platform, making it a live signal of startup hiring demand right now.
- For full-time hires at funded startups, a warm-intro model beats a cold job post because the best AI engineers rarely apply cold.

How we picked
- Engagement type: whether you can hire freelance, contract, full-time, or all three.
- Vetting model: what screening happens before a candidate reaches you, and who does it.
- Published rate range: what the platform or independent sources report as typical hourly or project costs.
- Time to first candidate: how quickly the platform says you can see a shortlist.
- Startup fit: whether the platform is designed for or commonly used by early-stage and growth-stage companies, based on the platforms' own stated audiences.
- We built Clera, so we included it and gave it a real downside the same as every other item.
1. Toptal
Best for: companies that need senior AI engineers for complex or production-grade builds and can pay premium rates.
Toptal claims to accept only the top 3% of applicants after a multi-stage screening process. It has served more than 35,000 clients since 2010, including Thumbtack, Bridgestone, and Motorola. You can hire on an hourly, part-time, or full-time contract basis. Independent sources put typical rates for AI engineers at $100–$250/hr.
Pricing: $100–$250/hr (independent sources; Toptal does not publish a rate card).
Why it made the list: The screening bar is the highest of any marketplace on this list. You spend less time filtering bad-fit profiles because Toptal does it before you see anyone.
Downside: Those rates make sustained full-time hires expensive. It is also slower to spin up than open marketplaces.
2. Upwork
Best for: companies that want to post fast, receive many bids, and own the screening themselves.
Upwork is the largest general freelance marketplace. AI engineers on the platform self-report rates of $35–$60/hr at the lower end, with senior specialists going up to $150/hr. You post a job, get bids within hours, and can hire by the hour or by milestone. There is no gatekeeping on who can apply.
Pricing: $35–$150/hr depending on experience; Upwork charges a service fee on top.
Why it made the list: Speed and volume. If you need someone this week for a defined scope, no platform moves faster. The breadth of talent means you can find niche skills like LLM fine-tuning or agent orchestration if you screen carefully.
Downside: No vetting means you bear the full screening burden. Quality varies widely, and the best senior AI engineers rarely browse Upwork for new work.
3. Arc.dev
Best for: companies hiring mid-to-senior remote AI engineers at rates between the open marketplace and premium vetted tiers.
Arc.dev pre-screens candidates and claims to surface the top 2% of applicants. It covers both freelance contracts and full-time remote placements. Rates for AI engineers sit at $60–$150/hr depending on experience, according to independent sources. The platform targets developers, designers, and other technical roles.
Pricing: $60–$150/hr (independent sources).
Why it made the list: Arc fills the gap between Upwork's speed and Toptal's price. You get screened profiles without paying a top-tier premium, and the full-time remote option is useful for startups building a distributed team.
Downside: Smaller talent pool than Upwork or LinkedIn, so niche subspecialties within AI (e.g., hardware-aware ML, reinforcement learning for robotics) may have thin supply.
4. Lemon.io
Best for: startups that need a vetted AI engineer to start within 48 hours on a full-time or part-time contract.
Lemon.io focuses on funded startups and enterprise teams. It advertises 1,500+ vetted and handpicked developers ready to start, with AI engineers requiring 5+ years of experience to pass its screening. Talent is sourced from the EU, Latin America, and the US. The platform promises a match in 48 hours.
Pricing: Not public (Lemon.io does not publish a rate card on its site).
Why it made the list: The 48-hour matching claim is the fastest timeline among the vetted platforms on this list. The startup focus means candidates understand equity, small teams, and fast iteration.
Downside: Pricing is opaque until you talk to sales, which makes budget planning harder upfront.
5. Turing
Best for: companies that want to hire at scale from a global remote pool of pre-vetted AI engineers.
Turing connects companies with remote AI and software engineering talent from a global candidate network. Independent sources place typical rates at $100–$250/hr for vetted senior AI engineers, putting it in the same tier as Toptal. Turing is often cited for scale: it suits companies filling multiple roles at once, not just a single hire.
Pricing: $100–$250/hr (independent sources).
Why it made the list: If you are hiring a whole AI team rather than one engineer, Turing's global supply and screening process can handle the volume in a way that boutique platforms cannot.
Downside: Less focused on startups specifically. Onboarding and account management can feel designed for enterprise procurement teams.
6. LinkedIn
Best for: companies that want the largest possible candidate pool and are willing to invest in direct outreach and sourcing.
LinkedIn has the broadest reach of any platform on this list. LinkedIn Talent Solutions lets you post jobs, search profiles, and run targeted outreach to passive candidates. AI engineers with public profiles are searchable by skill keyword, location, and current employer.
Pricing: Job posting costs vary by duration and targeting. LinkedIn Recruiter licenses are a separate subscription; pricing is not public.
Why it made the list: Volume. No other platform gets you in front of more AI engineers. It is also the default place candidates expect to hear from recruiters, so response rates on well-crafted messages can be solid.
Downside: Zero vetting. You are doing all the screening yourself, and competition for the same profiles is intense. Senior AI engineers get many InMails and ignore most of them.
7. Teamvoy
Best for: companies that need a managed team for production LLM and AI agent builds, not just an individual hire.
Teamvoy positions itself as a platform for hiring AI engineers focused on production-grade work. Its own site notes that freelance marketplaces optimize for speed and price, while a platform like Teamvoy is aimed at companies that need an accountable team for complex AI projects.
Stage: Suits growth-stage companies and enterprises running multi-month AI development projects.
Why it made the list: It covers a gap the other platforms miss: the managed-team model. If you want a squad that ships a working LLM product rather than individual contributors you coordinate yourself, Teamvoy is worth evaluating.
Downside: Published pricing and public client lists are limited, so it is harder to benchmark against competitors before a sales call.
8. Clera
Best for: VC-backed startups that want warm intros to AI engineers already open to startup roles, without cold job posts.
We built Clera. The model is different from every other platform on this list: engineers join once and create a profile, then companies see those profiles and bid on the ones they want. Clera makes a warm intro to the person hiring. According to Clera's own data, 95 companies currently have at least one open role on the platform. If you are trying to hire AI/ML engineers for your startup, the warm-intro model removes the cold-outreach step that kills most recruiting pipelines.
Stage: Seed through Series B startups.
Why it made the list: Candidates on Clera are already open to startup roles. You are not cold-messaging passive talent. The bidding model also signals genuine interest, which tends to produce better first conversations. See how AI companies are hiring right now for context on what the competition looks like.
Downside: The talent pool is smaller than Upwork or LinkedIn. If you need 20 AI engineers in 60 days, Clera is not the right tool.
How to choose
| Your situation | Best pick |
|---|---|
| Need someone this week, defined scope | Upwork |
| Building a full-time remote team, budget is flexible | Toptal or Turing |
| Seed or Series A startup, want warm intros | Clera |
| Mid-size company, $60–$150/hr sweet spot | Arc.dev |
| Need a managed team to ship an LLM product | Teamvoy |
| Sourcing passive candidates at scale |
If you are a startup founder without an internal recruiter, a warm-intro platform or a vetted marketplace saves you weeks of screening time you do not have. If you have a recruiter and a clear job spec, LinkedIn or Upwork gives you the highest volume fastest.
Budget matters too. Vetted platforms charge a meaningful premium over open marketplaces. If your AI role is well-defined and short-term, Upwork's lower floor ($35/hr) is hard to beat. For a founding AI engineer who will shape your whole stack, the screening Toptal or Turing does upfront pays for itself quickly. You can also cross-reference the best sourcing tools for startup recruiters to layer additional sourcing on top of any platform.
Frequently Asked Questions
On open marketplaces like Upwork, AI engineers typically charge $35–$150/hr depending on seniority. Vetted platforms like Toptal and Turing run $100–$250/hr. Full-time salaries vary widely by location and startup stage.
Upwork is the fastest for receiving bids, often within hours of posting. Lemon.io claims to match you with a vetted engineer within 48 hours if you need someone pre-screened.
Most vetted platforms use a multi-step process: an application filter, a technical interview or coding test, and sometimes a live problem-solving session. Toptal says it accepts the top 3%; Arc.dev claims top 2%.
A freelance engineer works on a contract or hourly basis with no equity or benefits obligation. A full-time hire joins your team permanently, usually with salary, benefits, and sometimes equity. Most platforms on this list support both models.
Ask for a take-home project relevant to your stack (LLM fine-tuning, agent design, RAG pipelines). Review their GitHub or past project work. Run a structured technical interview focused on real production decisions, not trivia.
Clera, Lemon.io, and Arc.dev are the most startup-oriented. Clera requires candidates to opt in to startup roles. Lemon.io's own homepage calls out startups as its primary audience.
Be specific about the stack (LLM framework, cloud provider, data scale), the problem you are solving, and the stage of the company. Vague posts attract generalists. Strong AI engineers want to know if the work is real and challenging. ---
