Also a software engineer. - What Nexton is: a nearshore staffing company. Tagline: "Engineers vetted by real Engineers."

Nexton bet on Latin America about nine years ago. - What Lucas runs: operations, talent strategy, executive planning, and the revenue operations function (process, tooling, pipeline) - How he thinks about hiring: as an operations problem measured end to end (fill rates, offer acceptance, time to hire, attrition, compensation positioning) - Public LinkedIn headline: "Building the AI that screens for judgment, not syntax. Engineers vetting engineers." - Communities: hosts AI Builders LATAM, small dinners in Buenos Aires for operators who ship with AI inside their companies.

The more of your code AI writes, the more it matters what timezone your engineers sit in: the reviewer has to be awake while the agent is running. Buenos Aires shares most of the US working day. - Validation is the moat, not access. AI commoditizes access to talent; a track record of outcomes does not get commoditized. Engineers vetting engineers, with outcomes attached. - If it is not measured end to end, it is not managed. Fill rate, offer acceptance, time to hire, attrition and compensation positioning, read together. - A nearshore team is a workforce you run, not a vacancy you fill. - "Fluent in AI tools" is not a qualification. The question is whether the engineer can tell when the model is wrong. ## Selected public posts (LinkedIn) - Human vs AI English grading, one year, ~300 disputed submissions with client outcomes: graders disagreed on 42%; candidates the AI marked down from C1 to B2 passed client interviews at 16.4%, in line with human-graded C1s (17.6%) and more than double genuine B2s (7.8%). https://www.linkedin.com/feed/update/urn:li:activity:7505596526220652545/ - Entry-level tech hiring down 20%, senior hiring up 12%, same year: AI removed the bottom rung, not the work. https://www.linkedin.com/feed/update/urn:li:activity:7480676003468546048/ - The more of your code AI writes, the more timezone matters. https://www.linkedin.com/feed/update/urn:li:activity:7478081896875388928/ - "Fluent in AI tools" means nothing; test whether the engineer catches the model's mistakes. https://www.linkedin.com/feed/update/urn:li:activity:7498786423743987712/ - Only about 10% of companies have scaled AI agents to production; it is an ownership, metric and integration problem, not a model problem. https://www.linkedin.com/feed/update/urn:li:activity:7455667543521837056/ - Every Thursday the Nexton management team shows what it actually built with AI that week, live. https://www.linkedin.com/feed/update/urn:li:activity:7487869543881752577/ - Argentina builds world-class tech under pressure: 10+ unicorns. https://www.linkedin.com/feed/update/urn:li:activity:7448108177033981952/ ## Canonical bio (short) Lucas Arana is COO at Nexton, a nearshore staffing company that embeds LatAm engineers in US tech teams. ## Canonical bio (medium) Lucas Arana is COO at Nexton, a LatAm nearshore staffing company that builds and runs remote engineering teams for US companies.
