About The Role

&lt;div class=&quot;content-intro&quot;&gt;&lt;p&gt;&lt;strong&gt;We Make Remote Work Remarkable&lt;/strong&gt;&lt;strong&gt; • TopTalent from LatAm&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;Hello! We are &lt;/span&gt;&lt;strong&gt;GoFasti, &lt;/strong&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;a Talent-as-a-Service. &lt;/span&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;GoFasti bridges the gap between world-class developers and designers from LatAm and first-class companies around the globe. &lt;/span&gt;&lt;/p&gt;&lt;/div&gt;&lt;p&gt;We need an English-fluent&lt;strong&gt; Senior Full-Stack Software Engineer&lt;/strong&gt;, based in NY, preferable Manhattan.&lt;br&gt;&lt;br&gt;We are looking for someone with exceptional communication and relationship-building skills, who embraces changes while maintaining strong attention to detail. An interested and proactive person, who&#39;s constantly learning and improving their skills.&lt;/p&gt;
&lt;p&gt;Are you the one we are looking for?&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Responsibilities:&lt;/strong&gt;&lt;/p&gt;
&lt;ul class=&quot;tiptap-list-disc&quot;&gt;
&lt;li&gt;
&lt;p&gt;A TypeScript monorepo: a Next.js 16 web app and API, an Expo mobile app, and a Cloudflare Worker.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;A PostgreSQL + Prisma data model with dozens of models and a long migration history, shared across apps.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Background systems: webhook handlers (Plaid, Stripe, Linq), queued inbound-message batching, and scheduled jobs.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Security-sensitive paths: encrypted bank tokens and chat content, per-user data scoping, auth across web and mobile.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;The AI layer: LLM tool-calling over users&#39; financial data, long-term memory, and proactive insights.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Reviewing AI-generated code, including your own, with a skeptical eye.&lt;/p&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;strong&gt;Requirements:&lt;/strong&gt;&lt;/p&gt;
&lt;ul class=&quot;tiptap-list-disc&quot;&gt;
&lt;li&gt;
&lt;p&gt;6+ years as a software engineer, 3+ years shipping production TypeScript/Node backends.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Shipped work at a company that moved money or handled bank or card data (Plaid, Stripe Treasury, Unit, Synapse-era BaaS, card issuing, lending, payroll).&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Deep PostgreSQL: migrations safe to run on live data, indexes, transactions, query plans.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Real experience with async systems: idempotency, retries, deduplicating webhooks, jobs that fail halfway.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;A security-first instinct around PII, encryption at rest, auth tokens and least privilege.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Solo ownership of production at least once: on-call, reading error tracking, writing root-cause analyses.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Daily use of AI coding tools (Claude Code, Cursor or similar), and clear views on where they go wrong.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Written English good enough that a PR description or incident write-up needs no follow-up questions.&lt;/p&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;strong&gt;It&#39;s a plus:&lt;/strong&gt;&lt;/p&gt;
&lt;ul class=&quot;tiptap-list-disc&quot;&gt;
&lt;li&gt;
&lt;p&gt;Plaid in production: webhooks, item re-authentication, transaction sync cursors.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;LLMs in production: tool-calling, prompt evaluation, cost and latency control.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Next.js App Router and React Server Components.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;SMS or messaging compliance (opt-outs, TCPA), or Stripe subscription billing.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Expo / React Native.&lt;/p&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;strong&gt;Compensation:&lt;/strong&gt;&lt;/p&gt;
&lt;ul class=&quot;tiptap-list-disc&quot;&gt;
&lt;li&gt;
&lt;p&gt;The salary range offered for this position varies from (USD) $9,200 - $10,000 per month, depending on seniority and skillset.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;This is a&lt;span class=&quot;Apple-converted-space&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;strong&gt;hybrid position with a flexible schedule&lt;/strong&gt;, the days and times you’ll need to be in the office may vary depending on business needs&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;This position is for a full time contract, through a payroll platform.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;The talent will work remotely allocated at our client.&lt;/p&gt;
&lt;/li&gt;
