Build with us
like you'd build in-house.

Hire Android developers who join your team, your repo, and your standups — backed by a 88-engineer Android organization that ships Kotlin-first, Material 3, modular Gradle apps across fintech (biometric auth, NPCI rails), retail (offline-first commerce), media streaming (ExoPlayer), and EMM/MDM-managed enterprise apps.

On your team, day 1

Engineers join your Slack, your Jira, your sprint board. No layers, no PM filter — they pair with your Android team like senior in-house hires.

Direct git access

They open PRs straight into your repo. You see every Kotlin file, every Compose composable, every Hilt module, every Espresso test, every Play Console release.

You manage the work

You set product priorities and sprint goals. We handle hiring, retention, payroll, benefits, upskilling, and laptops.

Hiring Process

From "we need a Android dev"
to onboarded — in 2 weeks.

4-step process pulled straight from how we work. 4 hours to first profile. 2 weeks to a Android developer joining your standup.

01
Day 1-2

Requirement Analysis

We begin by understanding your business goals, technical requirements, project scope, and timelines to ensure the right Android development approach for your team.

02
Day 3-5

Choose a Resource

Based on your needs, we shortlist and recommend the most suitable Android developers with relevant experience and skill sets — 3-5 profiles in 4 hours.

03
Day 6-10

Start an Interview

Interview the selected Android developers to assess their technical expertise, communication skills, and project fit before final selection. Live coding, system-design — your call.

04
Day 11-14

Onboarding

Once approved, the developer is onboarded quickly and starts working as part of your team with complete transparency and regular updates. First PR by day 14.

Why Choose WebSenor

10 reasons enterprises pick us
over over marketplaces and agencies.

01

5-step vetting

Resume + technical screen + live Kotlin + Compose coding test with Hilt/Coroutines + system-design + culture fit. <4% acceptance rate.

02

100% source code authorization

03

Skilled & experienced programmers

Our Android developers have shipped Kotlin-first apps across fintech (biometric auth, NPCI/UPI), retail (offline-first PWA + native), media (ExoPlayer streaming), and IoT (BLE).

05

Not the right fit? Free replacement in 5 business days. No questions asked. Most teams never need it — but it's there.

06

No middlemen

You talk directly to engineers. No account-manager wall, no chinese-whispers PM filtering communication.

07

08

Time-saving

Time is money. Our Android experts deliver projects effectively and efficiently, with 95% talent retention to avoid mid-project churn.

09

Frequently Asked Questions

Everything you need
to know before hiring.

What does the 14-day SLA actually mean?
From the discovery call (day 1) to the Android developer being onboarded and pushing their first Play Console internal build (day 14). Typical: shortlist by day 3-5, interviews day 6-10, MSA + Play Console access day 11-13, first AAB upload by day 14.
How does the replacement guarantee work?
If an Android developer isn't a fit, give us 5 business days notice. We send 2-3 replacement profiles within 4 hours. No replacement fee, no penalty.
Do your Android devs do Jetpack Compose, not just XML?
Yes. 85% of new Android builds we staff are 100% Compose with Material 3. We also keep a separate bench for legacy XML/Views migrations and hybrid Compose-in-Views modernization.
Can your team handle Compose Multiplatform / KMP?
Yes. We have a dedicated KMP bench — sharing domain models, networking, and validation between iOS and Android, with Compose Multiplatform for UI where teams want it. Already shipped to production in fintech and B2B SaaS.
What about Google Pay, biometrics, Play Integrity?
Standard. Our Android devs integrate Google Pay (and India UPI), BiometricPrompt, Play Integrity API for fintech, In-App Billing v6 / Play Billing Library, and Play Asset Delivery for large media.
How do you handle Android fragmentation?
We test on Firebase Test Lab + Gradle Managed Devices across API 24 → latest, plus a curated lab of low-RAM Indian + Latam devices. We tune Baseline Profiles for cold-start on mid-tier hardware.
What about IP, NDAs, and source code?
100% source code authorization. Standard MSA assigns all IP — including Play Console transfer on request — to you on day 1. NDAs signed before any shortlist.
How do you vet Android developers?
5 steps: 1) Resume + Play Store portfolio screen, 2) Technical screen with our Android lead, 3) Live Kotlin + Compose coding test (90 min) with Hilt + Coroutines, 4) System-design round (60 min) on offline-first, modular Gradle, multi-module Hilt graph, 5) Culture-fit + reference checks.
