We are a fast-growing telecom / AI-First CPaaS serving sms and voice API's. We are building the first AI-first communications platform (SMS, Voice, RCS, AI agents) designed for speed, simplicity, and real-world business outcomes. We are not looking for a “task completer.” We are looking for a true senior engineer who: thinks in systems moves fast makes decisions independently writes clean, scalable code uses AI tools (Claude, etc.) as a force multiplier ⚠️ Read This First *DO NOT APPLY IF YOU ARE PRETENDING TO BE IN A DIFFERENT COUNTRY. PROOF OF RESIDENCY IS REQUIRED. Most applicants will not be a fit. If you need: detailed tickets hand-holding constant direction This is NOT the role for you. If you are the type of engineer who: sees a problem and solves it end-to-end improves architecture without being asked ships quickly without sacrificing quality You will thrive here. What You’ll Do Build and ship full-stack features across our platform (messaging, voice, AI workflows) Make architectural decisions (not just implement) Improve system performance, reliability, and scalability Work directly with founders (no PM layers) Move from idea → production very quickly What We Expect (Non-Negotiable) 5+ years real full-stack experience (not just titles) Strong backend experience (Node.js / APIs / infra) Strong frontend experience (React or similar) Experience building production systems at scale Ability to work autonomously with minimal direction High ownership mentality Bonus (but highly valuable) Experience with telecom / CPaaS / messaging Experience with AI integrations (LLMs, agents, workflows) Experience optimizing performance at scale Startup experience (especially early-stage or fast growth) How We Work Small, high-output team Very fast iteration cycles No unnecessary meetings High trust, high expectations We use AI tools heavily (Claude, etc.) — you should too What We Care About Most Not your resume. We care about: How you think How you build How fast you execute The quality of your code To Apply Please include: Links to projects you’ve built (real production work) A short explanation of: a system you designed end-to-end a difficult technical decision you made independently Your GitHub Optional (but strong signal): Share how you use AI (Claude, etc.) in your workflow Compensation Competitive (based on experience) Long-term opportunity with a fast-growing, profitable company If you are truly senior, this will feel obvious. If not, this role will be very uncomfortable. **THIS IS A FT, HOURLY ROLE. PROVIDE YOUR REQUESTED HOURLY RATE IN PROPOSAL**

About the Role We're a growing digital media and technology company looking for an experienced part-time developer to serve as the bridge between our U.S.-based leadership team and our offshore development team in India. This is not a pure coding role — it's a communication, oversight, and execution role. You need to be technical enough to understand what we're asking for, translate it into clear specs and tasks, and hold developers accountable to deadlines and quality standards. What You'll Do - Receive project requirements and priorities directly from U.S. leadership - Break down requirements into clear, actionable tasks for the dev team - Oversee day-to-day development work across all active projects - Monitor progress, identify blockers, and keep projects on schedule - Review completed work for quality and alignment with requirements - Manage platform maintenance and ongoing technical operations - Serve as the primary point of escalation between leadership and the dev team - Provide regular status updates and flag issues proactively What We're Looking For - Native English speaker — clear written and verbal communication is non-negotiable - Solid development background (full-stack preferred) so you can evaluate technical work credibly - Experience managing or overseeing offshore development teams - Strong project management instincts — you know how to prioritize, push, and follow through - Comfortable working across multiple concurrent projects - Reliable, responsive, and self-directed - Familiarity with web platforms, email systems, and marketing tech is a plus The Details - Part-time, remote — flexible hours but must overlap with U.S. business hours (Eastern Time preferred) - Ongoing engagement with potential to grow

Deploy an existing Node.js/Express app and configure SMS. I have a complete, working dispatching app (Node + Express + SQLite, plain-JS frontend). I need someone to: (1) deploy it to Render or Railway with a persistent disk and HTTPS, (2) set up a Twilio account/number and wire in the credentials so it sends automated daily texts, (3) confirm the 6 AM scheduled texts fire reliably, and (4) be available for small tweaks afterward. Code, README, and deploy steps are all included. Should be a few hours for someone experienced. Please share similar Node deployment work you've done.

We run 4 bakery locations and buy supplies through one Walmart Business+ account. When we place an order, Walmart splits it into multiple shipments that arrive as separate charges. When they ship separately it even further complicates it and separates it from the original bulk order. We already use PO numbers in our orders to identify which store placed the order. We need a script that: (1) pulls our Walmart order history on a schedule, (2) groups shipments by PO number and consolidates the line items, and (3) creates one vendor bill per PO in QuickBooks Online via the QBO API. We need it to run weekly or nightly, ideally on a simple cloud scheduler. Ideally the developer has experience with Bill and Bill Payment solutions on QBO APIs. We want to own the code.

I am building an authentication library and a billing platform in Golang + Postgres. Auth-library is embedded only, while billing can be an embedded-library, and also a stand-alone application. The platform is intended to make it easy for Go-devs to write authentication (users register, OIDC, recover password, etc.), and manage billing their users (various billing providers in addition to Stripe, including crypto). These codebases are mostly written by AI (Claude Code and Codex) but the issue is that these tools suck. The write a lot of slop, and their systems don't work, and I don't trust them. With auth + billing, these are highly sensitive areas where we cannot afford to fuck up. Deliverables are: 1. a list of tasks the LLMs must do to refactor / fix these systems 2. a complete audit of all APIs (the surface areas / shapes that are used as system boundaries) 3. integration tests that will pass, if the LLM's code is correct 4. a complete security audit, to address any vulnerabilities / exploits possible I am only looking to hire someone in California / colorado. I want to work synchronously with them; for every hour you bill we'll be on a call together so that we can maximize communication bandwidth. I live in Denver, but I plan to move to SF soon. I'd be down to work together in person in the future, but for now we'll only be working synchronously-remotely. Human-written applications only. Template or LLM-written responses here will be rejected immediately. Please list your qualifications concisely. Don't say 'I am a Golang expert' say 'I worked at company X, and built system Y in Go which does Z.' Thanks for your time.
