DevEx Engineer at Customer.io – Remote Americas — Columbus
Traveler-Friendly Insight
Remote-First and Async-Friendly? Customer.io is a fully remote company, and this role explicitly covers LATAM, Canada, and the USA — a wide geographic spread suggesting meaningful timezone flexibility. The role emphasizes strong written communication and autonomous execution, both hallmarks of async-oriented teams. However, an on-call rotation is required, so you'll need reliable internet and some schedule predictability during your on-call windows.
Timezone Considerations: With the team spanning the Americas, expect overlap requirements roughly within UTC-8 to UTC-3. This suits nomads based in Latin America (Medellín, Buenos Aires, Mexico City) or even Western Europe during compatible hours. Southeast Asian bases (Bangkok, Bali) would create a significant timezone gap and are likely impractical given on-call duties.
Salary vs. Cost of Living:
- Medellín, Colombia: ~$1,500–$2,500/month comfortable. At $150K–$200K USD annually, your purchasing power is exceptional.
- Lisbon, Portugal: ~$3,000–$4,500/month. Strong purchasing power, though EU-based work may require a D8 digital nomad visa. Timezone could be a stretch.
- Mexico City, Mexico: ~$2,000–$3,500/month comfortable. LATAM eligibility makes this a smooth fit — Temporary Resident visa or tourist visa for shorter stints.
Travel Perks: Remote work stipend and wellness stipend are explicitly offered — useful for coworking memberships on the road. No mention of a dedicated equipment or coworking allowance beyond the general remote stipend.
Hi, I'm Josh, Engineering Manager at Customer.io. We're looking for a curious, AI-forward Developer Experience Engineer to join our Integrations team and help us build the tools that developers rely on to integrate with Customer.io.
About Customer.io
Over 9,000 companies — from scrappy startups to global brands — use our platform to send billions of emails, push notifications, in-app messages, and SMS every day. Customer.io powers automated communication that people actually want to receive.
We help teams send smarter, more relevant messages using real-time behavioral data. Under the hood: Go, React, Ember and AI help us ship fast and scale with confidence.
What We Value
Ownership
You own problems end to end. You move fast, act like an owner, and thrive in ambiguity. You've led complex projects before, whether officially or not, and you're ready to do it again.
Engineers with product taste
You think like a developer using your tools, not just an engineer building them. You care about API design, developer experience, and everything in between.
A healthy skepticism for "the way things are done"
You bring rigor and creativity. Best practices matter — but never more than forward motion.
What You'll Do
- Build and evolve Customer.io's SDKs across platforms — including Android, iOS, Node, and Go — and the developer tools that support them
- Lead SDK initiatives end to end: set technical direction, write the code, manage the release, and own the outcome
- Improve SDK delivery infrastructure — CI, automated testing, versioning, publishing, and release processes — so shipping is reliable and low-friction
- Partner closely with product and design to turn loosely defined goals into a great developer experience
- Participate in an on-call rotation as required, supporting the reliability of the systems you build
- Use AI agents to make multi-file changes across unfamiliar codebases and languages by scoping the work, writing the prompt, and verifying the output
- Bring strong customer empathy to the role — understanding what the engineers integrating with our SDKs actually need, and occasionally engaging directly with them
What We're Looking For
- Expert-level competency in at least one established programming language, with strong software design and API design fundamentals
- Experience building and evolving mature, production-quality software, with a clear understanding of how systems fit together and how other developers consume them
- Exceptional fluency with current LLMs and agentic coding tools (e.g., Claude, Cursor, Codex) — using AI to understand unfamiliar codebases, work across languages, and run things in parallel or autonomously
- High autonomy in ambiguous environments — you clarify the problem, validate its value, and drive implementation without close direction
- Strong written and verbal communication, with the ability to explain technical decisions and tradeoffs clearly
- Ability to work effectively across multiple languages and stacks; prior experience in every language we support (Swift, Kotlin, Node, Go) is not required
Nice to have: experience building external-facing SDKs, APIs, or developer tools; experience owning CI, testing, versioning, or release infrastructure; or forward-deployed engineering experience.
Compensation & Benefits
Starting salary for this role is $150,000 – $200,000 USD (or equivalent in local currency) depending on experience and subject to market rate adjustment. In addition to base salary, this role includes an equity grant in the form of stock options, so you share in the success you help build.
Our inclusive benefits package supports your well-being and growth, including 100% coverage of medical, dental, vision, mental health, and supplemental insurance premiums for you and your family. We also offer 16 weeks paid parental leave, unlimited PTO, stipends for remote work and wellness, a professional development budget, and more.
Our Process
No gotchas, no trick questions — just a clear, human process designed to help both of us make an informed decision.
- Application — We review everyone with care. Tell us why you're interested.
- Recruiter Call (30 mins) — Let's chat about what you're looking for and how we work.
- Hiring Manager & AI Skills Interview (60 mins) — We'll explore ownership, autonomy, and collaboration, then dig into how you actually use AI in your day-to-day workflow.
- Practical AI-Enabled Coding Round (60 mins) — A live, collaborative session where you'll extend a sample SDK using AI tools. We want to see how you think and work with AI as part of your process.
All final candidates will be asked to complete a background check and employment verifications as part of our pre-employment process.
Customer.io recognizes the stifling impact of systemic injustice on diverse communities. We commit to using our influence to increase inclusion and equity within the tech industry.
