Job description

Our client is a remote product studio that builds MVPs and custom software for startups and companies past the idea stage. Clients pay for each build, and a small team works in two-week sprints with AI coding tools used every day. Clients are startup founders and their teams, so developers explain tradeoffs to them directly.

They've been at it since 2020 and were profitable in 2025, with a 30% net margin. After building their own AI systems, they tripled monthly revenue with the same team size. Clients rate them 4.9 out of 5 in verified reviews, and the startups they build for have raised more than $25M in venture funding.

Your Role

You'll be the only mobile developer on a new offline-first iOS and Android app, starting from the first project setup. The developer accounts, build pipeline and release tracks don't exist yet, so that's where you begin, and you stay on the same app through its public launch on the App Store and Google Play.

Sprints run two weeks with four to five features each, and coding agents write most of the first draft. You review every diff, add the tests the agents missed, and make the calls on sync, storage and releases. If you'd rather have a QA team or a release manager handle testing and store submissions, this probably isn't the right seat.

You report to the studio's leadership and work day to day with the lead developer and a backend developer, who's your counterpart on the sync and upload APIs. You'll also write risk notes and tradeoffs directly to the client team, with your recommendation attached. Success means sprints that close with their acceptance criteria verified, a write queue that neither loses nor doubles a submission on real devices, and an app live on both stores where sync failures show up in monitoring before anyone reports them.

You’ll:

Set up Apple and Google developer accounts, signing, CI builds and testing tracks

Build the local storage, write queue and retry logic that keep the app working offline

Agree the sync and upload APIs with the backend developer, and decide how conflicting edits resolve

Build phone-number sign-in with SMS codes, and push notifications that fall back to SMS

Build camera capture and e-signature flows that save each signed record as a new version

Measure and improve startup time, memory and app size on low-end Android phones

Handle store submissions, privacy disclosures and review rejections, and add crash and sync monitoring

You Bring

4+ years building mobile applications, including React Native applications released on both the App Store and Google Play

Offline-first work you built yourself: local storage, queued writes, retries and conflict handling

Performance tuning on low-end Android, with startup time or memory measured before and after a change

Daily use of Cursor, Claude Code or a similar AI coding tool on production mobile work, with TypeScript, automated tests and CI around it

Clear written and spoken English for PR descriptions, risk notes and tradeoff explanations to a client team

Experience working from written acceptance criteria, and the judgment to push back on a merge that misses them

Bonus Points

An in-app e-signature or document flow that stored versioned records

An application built for field, frontline or hourly workers

A localized application, or Spanish for testing the interface

Backend work such as writing an endpoint or a database migration

Crash reporting or sync monitoring you set up and then used to fix a problem seen in the field

What's Offered

Fully remote contractor role from LATAM, full time at about 40 hours a week

Core hours in US time zones, overlapping with the lead developer and the backend developer

One app to own, from the first project files through public release on both stores

Sync, storage and release decisions that are yours to make, with a backend developer as your counterpart

A team where AI coding agents are part of the daily workflow, with typed code, automated tests and CI in place

Interview Process

Intro Call: 30 minutes with atomic HR on your background and goals
Leadership Screening: A short call, possibly with an async part first
Product and Developer Conversation: How you take features to merge and agree sync APIs
Take-Home Test: One feature like the real scope, built and checked

Get to Know Darwoft

At Darwoft, we build custom software solutions and partner with international companies to create high-impact digital products.

We are a Latin American technology company with a people-first culture, strong professional standards, and a long-term partnership mindset. We work with distributed teams, complex technical challenges, and clients whose technology has a direct impact on their businesses and users.

About the Project

We are partnering with an innovative cybersecurity company developing a modern Identity Security and Identity Observability platform.

The product enables enterprise security teams to monitor identity activity, identify security gaps, detect suspicious behavior, and reduce identity-related risks across cloud, SaaS, network, and on-premise environments.

Its architecture relies heavily on distributed systems, real-time data processing, cloud-native infrastructure, advanced analytics, and an increasingly AI-driven security roadmap.

As the platform continues to scale, infrastructure reliability, automation, observability, security, and developer productivity are critical engineering priorities.

About the Role

We're looking for a Senior DevOps Engineer to design, automate, operate, and continuously improve the cloud infrastructure and deployment platform supporting a high-scale cybersecurity product.

You’ll work primarily with AWS, Kubernetes/EKS, Terraform, Docker, CI/CD, and observability technologies, partnering closely with Software Engineering, QA, Security, and IT teams.

This role goes beyond maintaining infrastructure. You’ll actively contribute to platform engineering, helping engineers ship software faster and more reliably while improving automation, security, operational visibility, scalability, and cloud cost efficiency.

You’ll have a high degree of ownership over production infrastructure and participate directly in architectural decisions, incident resolution, platform improvements, and DevOps best practices.

What You'll Be Doing

• Design, build, and operate highly available and scalable cloud infrastructure primarily on AWS.
• Build and maintain Infrastructure as Code using Terraform.
• Deploy, manage, scale, and troubleshoot workloads running on Kubernetes, particularly Amazon EKS.
• Develop automation for infrastructure provisioning, environment configuration, and application deployment.
• Build and maintain reliable CI/CD pipelines using tools such as GitHub Actions, Jenkins, or GitLab CI.
• Improve deployment processes, release reliability, and developer experience across engineering teams.
• Manage containerized applications using Docker and Kubernetes.
• Design and improve observability across infrastructure and applications.
• Implement monitoring, dashboards, alerts, and centralized logging using technologies such as:
  • Prometheus
  • Grafana
  • AWS CloudWatch
  • OpenSearch / Elasticsearch
  • ELK
• Participate in production incident response, troubleshooting, mitigation, and root cause analysis.
• Identify recurring operational issues and automate their resolution.
• Implement AWS and Kubernetes security best practices.
• Collaborate with Security teams to strengthen infrastructure security and support compliance initiatives.
• Improve platform resilience, high availability, scalability, and disaster recovery capabilities.
• Optimize AWS resource utilization and contribute to cloud cost optimization and FinOps initiatives.
• Automate operating system and infrastructure configuration using Ansible or similar tools.
• Develop operational tooling and automation using Python and Bash.
• Collaborate with Engineering teams on platform architecture and deployment strategies.
• Continuously evaluate new DevOps, cloud, Kubernetes, observability, and platform engineering technologies.

What You Bring

• 5-8+ years of experience working in DevOps, Platform Engineering, Site Reliability Engineering, Cloud Engineering, or similar roles.
• Strong hands‑on production experience with AWS.
• Strong experience managing Kubernetes clusters, ideally Amazon EKS.
• Advanced experience with Terraform and Infrastructure
