L2 Support Engineer (Application Support Engineer)

About Lifted: Lifted is a premier, internationally recognized workforce solutions innovator, technical talent accelerator, and digital systems platform pioneer operating on an absolute mission to protect, optimize, and scale the delivery parameters of enterprise-grade software properties. Partnering hand-in-hand with an industry leader in telecommunications analytics, secure international roaming infrastructure, and end-to-end domestic signal testing validation architectures, Lifted untangles highly complex delivery bottlenecks for fast-scaling network carriers globally. Driven by a craft-led, performance-oriented workplace philosophy centered around deep technical curiosity, transparent stakeholder collaboration, and rigid data validation hygiene, the organization provides high-agency application support engineers with an uncompromised remote canvas to leverage state-of-the-art diagnostic ecosystems, manipulate complex multi-tier codebase dependencies, and deploy robust system hot-fixes safely across Portugal.

Position Overview

We are seeking a highly analytical, detail-obsessed, and systems-minded L2 Support Engineer (Application Support Engineer) to join our core centralized Customer Support collective in a full-time 100% remote capacity open exclusively to qualified technical engineering specialists resident within Portugal. Operating at the high-stakes runtime core of our enterprise telecom analytics product line, you will step up to claim true individual operational and strategic accountability for troubleshooting, maintaining, and certifying the stability of applications managing intricate data streams for global roaming safety, fraud mitigation, and risk controls. Shifting completely away from routine passive inbound text logging, minor non-technical account modifications, simple template script updates, or basic call forwarding loops, you will run an active software diagnostic laboratory—partnering face-to-face with enterprise network managers, internal tier-3 infrastructure specialists, and core backend developers. This position requires an internet tech or telecommunications domain veteran with 5–7 years of industry depth who maps out system debugging tracks fluidly natively using Backend programming architectures, handles multi-tenant customer service requests smoothly natively using Technical Support frameworks, and commands low-level Linux environments and automated script writing confidently under strict production SLAs.

Key Responsibilities

• Full-Lifecycle L2 Application Support: Investigate, diagnose, and resolve complex Level 2 and Level 3 customer service requests (CSRs) for high-concurrency telecom analytics ecosystems, enforcing uncompromised quality standards cleanly natively utilizing Technical Support playbooks.
• Deep-Dive Product Log Scrutiny: Analyze, trace, and audit dense application-layer system logs, drawing structural parallels with active product code repositories to locate root-cause failure components cleanly natively leveraging Backend code models.
• B2B Stakeholder and Customer Diplomacy: Engage transparently and communicate technical resolutions clearly before international client networks, enterprise telecoms managers, and cross-functional internal stakeholders over secure call and email queues.
• Collaborative Hot-Fix and Patch Formulation: Partner in lockstep with centralized backend engineering squads to co-develop, test, and implement custom code patches or emergency hot-fixes for intricate product defects.
• Linux Environment and Scripting Engineering: Author, refine, and maintain runtime shell automations and system diagnostic macros across bare-metal or cloud-based Linux server infrastructures, coding fluidly with Shell or Perl scripts.
• Rigorous Core Java Source Tracking: Maintain and expand a comprehensive functional understanding of the product lines underlying codebase, utilizing Core Java object-oriented principles to trace variables and isolate logical anomalies.
• Product Upgrade and Installation Governance: Assess, plan, and execute technical validation pathways for complex product updates, core microservices installations, and configuration migrations across client profiles.
• Product Enhancement Feedback Loops: Channelize, translate, and prioritize empirical field observations and client feedback items back into the engineering core to drive programmatic future product refinements.

Required Skills & Qualifications

• A minimum of 5 to 7 years of verified professional history running advanced application support engineering, software-systems diagnostics, telecommunications technology development, backend programming, or infrastructure consulting.
• Mandatory Support Tier Sourcing Background: A minimum of 4 years of dedicated career experience explicitly base-stationed in an L2 Support Engineer capacity, technical infrastructure tier desk, or customer-facing operations engineering seat (ideally tracking a core background inside the telecommunications sector).
• Expert-tier capability mapping system dependencies, parsing machine data, and managing code tracing arrays natively utilizing Backend logic (specifically requiring deep proficiency with Core Java).
• Practical operational familiarity organizing helpdesk queues, managing ticket macro scripts, and tracking SLA lifecycles natively using Technical Support parameters (complemented by profound familiarity with Linux operating systems and Shell/Perl scripting).
• Outstanding written, verbal, and scannable technical-documentation communication traits in business-fluent English to seamlessly resolve complex queries across cross-border pods.
• Educational Sourcing Alignment: Formal university education or matching quantitative degree track in Computer Science, Electronics and Communication Engineering, Telecom Engineering, or closely allied digital domains.
• Location Context: Position open exclusively to qualified application support engineers based permanently and resident within the borders of Portugal to operate under a 100% remote work-from-home layout.

Preferred Strategic Indicators (Nice to Have)

• Prior commercial media or engineering history operating explicitly brand-side or vendor-side for a global cellular carrier, roaming network clearinghouse, or SMS/voice routing gateway.
• A proven programming background, possessing 2 to 3 years of formal career experience working as a dedicated backend developer or software code author.
• An outcome-driven personal philosophy rooted in high architectural curiosity, an independent self-managing operator style that remains calm under volatile outage timelines, and an intense passion for building diagnostics loops that make global networks trusted.

What We Offer

• Vetted Global Telecommunications Contractual Blueprint: A competitive full-time baseline annual contract compensation package calibrated precisely to evaluate your application support authority, Core Java craftsmanship, and telecom domain depth under a stable long-term framework.
• The exceptional professional canvas to claim absolute diagnostic execution ownership over the analytics pipelines protecting enterprise roaming and security loops for major global networks.
• Profound work-from-home remote parameters offering a 100% remote virtual environment within Portugal, complete scheduling trust to manage troubleshooting tracks, and zero physical geographic office commuting friction out of any district.
• Immediate baseline integration into an intensely collaborative, engineering-led tech collective built entirely on professional development, knowledge sharing, and data transparency.
