We have a team of over 1,400 dedicated engineers who either support our clients or serve as their Research and Development department. Our strong productivity allows us to speed up product development, giving our clients a competitive edge at a better cost-effectiveness.
As a rapidly growing employer, Sioux values its employees' growth and well-being. We invest in their career development and foster a positive work environment that promotes personal and professional growth.
SIOUX IN SINGAPORE
Sioux Singapore plays a pivotal role in the Asian market by offering R&D services from our centers across Europe and Asia to customers, leading development teams in Asia, from Singapore
This expansion allows us to meet the changing needs of our domestic and international (OEM) customers in the semiconductor, analytical, and medical industries.
About the role
We build software at the intersection of precision hardware and high-stakes production — control systems for semiconductor equipment, data analytics platforms that help fabs improve yield and process stability. Our clients include leading international OEMs and China's most ambitious domestic wafer manufacturers.
As a Software Tech Lead, you will own both technical execution and practical project delivery for the team. You are expected to understand the software architecture, guide implementation decisions, support the development team technically, and also take responsibility for planning, progress tracking, risk follow-up, scope coordination, and client-facing communication. You will work closely with Software Architects, developers, and client stakeholders to ensure that complex semiconductor software projects are delivered with technical quality, realistic commitments, and clear alignment.
What you'll do
Internal — technical leadership and project delivery ownership
Lead the technical breakdown of software requirements into clear implementation tasks, acceptance criteria, risks, and dependencies
Guide software design and implementation decisions, ensuring alignment with architecture, maintainability, integration constraints, and delivery priorities
- Support developers in resolving technical issues, reviewing approaches, identifying root causes, and removing engineering blockers
- Own practical project management activities within the team, including delivery planning, task tracking, milestone follow-up, dependency management, risk escalation, and coordination of actions needed to meet commitments
- Build realistic technical delivery plans with the team, track progress against commitments, communicate status clearly, and adjust priorities when scope, risks, or dependencies change
Maintain technical clarity through design notes, decision logs, interface assumptions, action items, and acceptance criteria
External — technical communication, scope coordination, and stakeholder alignment
Act as a technical counterpart for international OEM clients and domestic fab customers across the Asia region, especially during requirement clarification, integration discussions, and delivery reviews
- Translate technical constraints, design trade-offs, risks, and implementation progress into clear language for client stakeholders and project teams
- Lead scope, feasibility, schedule, and change-impact discussions from a technical delivery perspective, helping stakeholders understand realistic commitments, engineering trade-offs, priority choices, and risks
Facilitate technical meetings, design reviews, issue triage sessions, and integration discussions while keeping decisions and follow-ups concrete
Collaborate with Software Architects during pre-sales and project ramp-up to ensure proposed solutions are technically sound and deliverable
Required
5+ years of software development experience, including experience leading technical delivery or guiding a small engineering team
Solid software programming background, with the ability to read, discuss, and challenge software designs and implementation approaches
Experience with software architecture, debugging, integration, code review, and technical decision-making in complex software systems
- Ability to understand technical details deeply enough to guide developers, identify risks, explain trade-offs, and align engineering work with delivery commitments
- Ability to manage practical project delivery activities such as planning, progress tracking, milestone follow-up, risk management, dependency coordination, and clear stakeholder communication
Preferred
Familiarity with semiconductor manufacturing concepts, including process flows, equipment types, and industry standards such as SECS/GEM and GEM300
Experience with equipment control software, factory host communication, motion control, machine vision, SCADA/MES integration, or other industrial automation software domains
Hands-on experience with programming languages commonly used in industrial or equipment software environments, such as C++, C#, Java, Python, or similar technologies
Experience coordinating across multi-site engineering teams in Asia, including Singapore, Vietnam, and China
Scrum Master certification, PMP, or equivalent delivery/project management experience is a plus, but not a substitute for software technical leadership capability
What this role is not
This is not a pure project management role and not a pure coding role. The successful candidate must combine software technical leadership with practical project ownership. They should be comfortable discussing software design, implementation trade-offs, integration risks, technical dependencies, schedules, scope, priorities, and delivery commitments with engineers, architects, and clients. You do not need to be the sole architect, but you must be strong enough technically to guide execution and disciplined enough to drive follow-up, coordination, and delivery closure.
Why this role
Technical leadership in a demanding semiconductor software domain requires both engineering depth and delivery awareness. The problems are complex, the clients are sophisticated, and the margin for misunderstanding is low. You will stay close to the software, guide the team through technical decisions, develop genuine domain knowledge, and have visible influence over what ships — and how well it works.
We welcome candidates from industrial automation, scientific instrumentation, or other precision-engineering software domains — deep semiconductor experience is not a prerequisite.
WHAT WE CAN OFFER
Our employees are our strength and together we want to achieve the maximum. That is why we invest a lot in our employees, through generous development budgets and personal attention. According to our employees, this is what makes the difference at Sioux. We are proud of that. For us, success is more than just a good salary: it is also about feeling valued, getting responsibilities, and to be able continuously develop oneself.
No matter how experienced you are, you will continue to develop yourself on a personal level and in terms of content. You have a personal training budget of 5,000 SGD available for this, every year.
Varied work due to the diversity in technologies, markets, and projects
An open culture that focuses on collaboration, learning, and having fun
An innovative work environment
